Hitching a free ride into the weekend like...
Remoras and manta rays have what scientists call a mutualistic relationship, where both organisms benefit from each other. Remoras cling to the body of the ray, catching a free ride, food scraps, and increased protection. All the while, the manta ray enjoys a spa treatment as the remoras clean its skin of parasites and bacteria. Talk about giving new meaning to, "I've got your back!"

On Friday the 13th in June 1930, the coal schooner, Paul Palmer, started its last voyage. In travel, the vessel caught fire and sank off Race Point, Massachusetts near NOAA's Stellwagen Bank National Marine Sanctuary. Although luck did not favor the schooner, the wreck is now home to a variety of marine life forming an artificial reef over time. Historic wrecks like Paul Palmer are time capsules that hold our stories from the past.

Just cruisin' by! Spotted in NOAA's Flower Garden Banks National Marine Sanctuary, whale sharks are gentle giants. Even with their massive size (sometimes even growing up to 40 feet long!) these creatures eat mostly small organisms like plankton, schooling fish, and squid. While it is still uncertain how long they can live, scientists predict a lifespan from 60 to 100 years!

Celebrate Manatee Awareness Month with us by showing this gentle friend some love. In the winter months, these mammals can be found grazing in the shallow waters of NOAA Florida Keys National Marine Sanctuary. Unfortunately, they are endangered largely due to human activity. Manatees are slow-moving and therefore unable to swim quickly away from boats, resulting in collisions. In areas that are known manatee habitats, be sure to slow down and keep an eye out!

Happy 48th anniversary to the Marine Mammal Protection Act!
Marine mammals are vital to the balance of marine ecosystems and are key indicators of the overall health of the ocean. First enacted in 1972, the act has since played a role in preventing marine mammal populations from declining to a point where they are no longer a functioning element in their ecosystems.

It's turtle-y Tuesday!
Do you know what kind of turtle this is?
If you guessed hawksbill sea turtle, you would be correct! Hawksbills get their name from their unique beak-like mouths. Their head comes to a point and their lower jaw is v-shaped, giving it a hawk-like appearance. This friend was found cruising in NOAA National Marine Sanctuary of American Samoa!

Happy Anniversary to NOAA Thunder Bay National Marine Sanctuary-our Great Lakes sanctuary turns 20 today!
Located in northwestern Lake Huron, Thunder Bay is adjacent to one of the most treacherous stretches of water within the Great Lakes system. Unpredictable weather, murky fog banks, sudden gales, and rocky shoals earned the area the name "Shipwreck Alley." Today, the 4300-square-mile Sanctuary protects one of America's best-preserved and nationally-significant collections of shipwrecks-over 200 vessels. Bring out your party hats for this one, folks!

It's the first day of October and that means it is time for spooky season! Check out this whale fall found by researchers aboard E/V Nautilus last year in NOAA's Monterey Bay National Marine Sanctuary. When a whale dies at sea, its body sinks to the seafloor and begins to decompose. First, scavengers consume the whale’s soft tissue. Then, invertebrates colonize the skeleton and microbes feed on sulfides from the bones. If that doesn't put you in a spooky mood, we don't know what will!
Make sure you tune in October 3rd-15th when exploration resumes with Nautilus Live in the sanctuary!

"Here, I brought you another stick..."
These osprey in Mallows Bay-Potomac River National Marine Sanctuary are collecting sticks to build up their nest. Osprey construct their nests on top of dead trees, power poles, on manmade nesting platforms, and sometimes on buoys, chimneys, or other structures. The nests are often used year after year and can become up to 10 feet high as more nesting materials are added each breeding season.

On September 3, 2019, NOAA made history by designating Mallows Bay-Potomac River National Marine Sanctuary, the first national marine sanctuary in almost two decades. The sanctuary protects the remnants of 118 World War I-era wooden steamships, collectively known as the Ghost Fleet.
The new sanctuary also protects heritage sites of the Piscataway-Conoy and other Indigenous peoples, as well as remains of historical fishing operations and Revolutionary and Civil War battlescapes. Plan your visit to paddle, fish, watch wildlife, and learn about the culture and history that live in this special place. Join us in wishing our newest sanctuary a happy 1st birthday!

This pink siphonophore is a great example of teamwork at play. While this may appear to be one organism, it is actually comprised of many zooids directly connected to each other by tissue. The interaction between the individual zooids is so strong that, together, they assume the function of a single, larger organism! This is just one example of the fascinating creatures that inhabit Channel Islands National Marine Sanctuary!

Have you met the star of the tide pool? The organisms living within tide pools are repeatedly covered and abandoned by shifting tides, leaving them to cope with extreme physical, chemical, and biological changes. Sea stars, like this one in Olympic Coast National Marine Sanctuary, use tiny tube feet on each arm to grip onto rocks. Make sure to step lightly while exploring tide pools in order to protect these inhabitants!

How did the hammerhead shark do on their test? They nailed it!
As Shark Week comes to a close, we had to show off this hammerhead shark in NOAA Gray's Reef National Marine Sanctuary (and share a dad joke). Sharks are magnificent creatures, but often misunderstood: we seem to be a far greater threat to them than they are to us, as sharks are frequently caught as bycatch, while they provide a crucial ecosystem service by keeping marine food webs in check.

Pop quiz: Is a whale shark a whale or a shark?
Correct Answer: A shark! While whales are mammals, whale sharks, like this one in NOAA's Flower Garden Banks National Marine Sanctuary, are actually cartilaginous fish. They get their name from their enormous size, sometimes stretching to around 40 feet long. Despite being the largest shark in the ocean, whale sharks are gentle giants, feeding primarily on plankton.
*Bonus fact*: Notice those white spots? Those are unique to each individual, just like a human fingerprint!

Join us in shellebrating NOAA Olympic Coast National Marine Sanctuary's 26th birthday! Protecting over 3,000 square miles of ocean, this sanctuary is home to a wide diversity of marine life, including this orange sea anemone, orcas, sea otters, and many more of our favorite ocean critters. In addition to important ecological resources, the sanctuary has a rich cultural and historical legacy. The vibrant contemporary communities of the Makah Tribe, Quileute Tribe, Hoh Tribe, and Quinault Nation have forged inseparable ties to the ocean environment along the Olympic Coast. There are even shipwrecks, their remains broken by the intense natural forces of the coastline or concealed from us in deeper parts of the Sanctuary. There is definitely a lot to celebrate here!

Shipwreck central! Lying beneath the waves in Papahānaumokuākea Marine National Monument is the Dunnottar Castle shipwreck. Built in Glasgow in 1874, this three-masted British ship got lost on its way to California due to a malfunctioning chronometer, and crashed into the reef. The crew abandoned ship, leaving the wreck to disappear under the surface until it was discovered by Kure Atoll refuge staff many years later. Today, this well-preserved artifact is home to a wide variety of marine life, and provides skilled divers with a window into the past.

Did you know that NOAA Gray's Reef National Marine Sanctuary off the coast of Georgia is one of the largest near-shore "live-bottom" reefs of the southeastern United States? "Live bottom" is a term used to refer to hard or rocky seafloor that typically supports high numbers of large invertebrates such as sponges, corals and sea squirts. These spineless creatures thrive in rocky areas, as many are able to attach themselves more firmly to the hard substrate, as compared to sandy or muddy "soft" bottom habitats. How many different creatures can you spot in this live-bottom reef?

Feeling crabby that it's already Sunday? Maybe some new food will help! Did you know this clawsome kelp crab in Monterey Bay National Marine Sanctuary changes its diets with the season? During the summer, when algae are plentiful, kelp crabs are mainly herbivores. However, when the algae diminish in winter, these crabs switch to a carnivorous diet, eating mussels, barnacles, and hydroids. Now that is eating seasonally!

Coming through! Sand tiger sharks, like this one in Monitor National Marine Sanctuary, may look scary, but this species is known to be rather docile. Interestingly, sand tiger sharks sometimes come to the surface and gulp down some air. No— they aren’t doing this to breathe, but rather to hunt. By storing this air in their bellies, sand tiger sharks are able to float motionless in the water and stalk prey. What do you think this technique should be called?

Today we honor King Kamehameha, a legendary figure in Hawaiian history. In 1810, Kamehameha united the Hawaiian Islands into one kingdom and became the first ruler. A fierce and determined warrior, Kamehameha spent decades navigating tricky alliances and battling powerful chiefs, all in the relentless pursuit to unite and rule the Hawaiian Islands. Called Kamehameha the Great, he established the “law of the splintered paddle,” or Ke Kānāwai Māmalahoe in Hawaiian, which was adapted in 1978 to become part of the Hawaii State Constitution. Today, this breathtaking environment is protected by Hawaiian Islands Humpback Whale National Marine Sanctuary.

Enjoyment and appreciation of the great outdoors is a fundamental American value. Like our iconic national parks, national marine sanctuaries are places of hope, inspiration, biodiversity, and resilience. But they are more than just ocean parks; they’re communities with diverse cultures, values, and ideas. By embracing and celebrating this diversity, we can ensure a bright future of our ocean and Great Lakes for current and future generations.
Whether you live on a coast or in a community far from the shore, we invite you to experience the power and beauty of America’s sanctuary system and form your own lasting memories.

Is anyone else having a hard time figuring out where this common octopus ends and the habitat starts? Divers found this camouflaged friend in NOAA Gray's Reef National Marine Sanctuary blending into their surroundings! Using a network of pigment cells and specialized muscles in its skin, this invertebrate can almost instantaneously match the colors, patterns, and even textures of its surroundings. Predators swim by without even noticing it. Keep an eye out for creatures hiding in plain sight on your next trip!

Dr. Isabella Kauakea Aiona Abbott has been called “the First Lady of Limu.” She was the first Native Hawaiian to earn a doctorate in science, the first female biology professor at Stanford University, and an internationally recognized authority on marine algae, or limu in Hawaiian, bringing unique ancient Hawaiian knowledge to her studies and teachings. She was the author of eight books and more than 150 scientific papers. She named more than 200 species, as well as naming NOAA’s research vessel, Hiʻialakai, which in Hawaiian means “embracing pathways to the sea.” Isabella was a towering inspiration to generations of students and colleagues due to her achievements, connections to people, and a lifelong passion for limu. She was a member of the Reserve Advisory Council from 2001 until her passing in 2010. In a fitting tribute, researchers at Papahānaumokuākea Marine National Monument named a recently discovered species of limu from Papahānaumokuākea after Isabella: Martensia abbottiae.

This rose has a different kind of thorn! Found in NOAA Channel Islands National Marine Sanctuary, the white-spotted rose anemone has specialized stinging cells in the tentacles surrounding its mouth. When prey or predators swim by, a barbed poisonous hook is ejected that can paralyze or even kill the target. Have you seen one of these anemones when diving in your sanctuary?

Hawaiʻi, the most isolated archipelago in the world, was globally connected in the 19th century due to the efforts of King David Kalākaua of the Hawaiian Kingdom, who reigned from 1874 to 1891. An educated and charismatic leader, he is the first head of state to circumnavigate the globe. His intellectual and artistic pursuits included science, law, music composition, military strategy, history, and new technology. Kalākaua, an avid inventor, met Thomas Edison in New York in 1881. By 1887, his home ʻIolani Palace boasted 325 incandescent bulbs four years before the White House acquired electric lights. His leadership inspired his people to take pride in their intellectual and cultural heritage. Kalākauaʻs vision of a vibrant nation is embodied and expressed by the cultural practitioners and artists at the annual Merrie Monarch Festival held in Hilo, said to be the “Superbowl” of hula and Hawaiian culture.

Crush, is that you? Today is the 20th anniversary of World Turtle Day, which was created to shell-ebrate and help protect turtles around the world. Our National Marine Sanctuary System is home to many species of turtles, including this green sea turtle, or honu, in Papahānaumokuākea Marine National Monument. They grow to 200 pounds or more and migrate once every two to five years across hundreds of miles of open ocean to mate and nest in the Northwestern Hawaiian Islands at French Frigate Shoals.!

Today is the International Day for Biological Diversity! Did you know that coral reefs are one of the most diverse ecosystems on the planet?
Sometimes called rainforests of the sea, coral reefs support more species per unit area than any other marine environment. Having high biodiversity helps make these ecosystems more resilient to change. Healthy and diverse reefs, like this one in NOAA Florida Keys National Marine Sanctuary, are key to discovering new medicines, contributing to local economies, and protecting shorelines. Always remember to practice responsible recreation to protect these beautiful biodiverse ecosystems!

The Hawaiian language was once on the verge of extinction. In 1984, there were less than 50 children that could speak fluently. It was then that the Hawaiian language revitalization movement began through the establishment of preschools that used immersion Hawaiian language-medium education. Today, Hawaiian language is an official language of the state of Hawaiʻi and Hawaiian language-medium education is present from preschool to Ph.D., an enormous accomplishment that has taken several decades. At the University of Hawaiʻi at Hilo the doctorate program in Hawaiian and Indigenous Language and Culture Revitalization is the first doctorate in the United States conducted in an Indigenous language and the first doctorate in the world to revitalize an Indigenous language.
To support the normalization of Hawaiian language and to accomplish the stewardship goals of Papahānaumokuākea Marine National Monument, the Mokupāpapa Discovery Center in Hilo provides bilingual interpretation for the growing number of Hawaiian language speakers.

Asian American/Pacific Islander Heritage Month is here, and we are celebrating our sanctuaries’ unique historic and cultural identities. The Siapo (or Tapa) is one of the oldest art forms in Polynesia, and each design motif is a symbol originating from Samoa’s natural environment. The Siapo shown here was created for NOAA National Marine Sanctuary of American Samoa by the Samoan artist Reggie Meredith, using a traditional Siapo mamanu form. The sanctuary's visitor center, the Tauese P.F. Sunia Ocean Center, is octagonal in shape to match this Siapo’s eight sections (or motifs).

Manu-o-Kū, or white terns, are known by traditional Hawaiian navigators as one of the best indicators of land. Manu-o-Kū go out to sea in the morning to feed on fish, and return to land at night to rest. The flights of such birds are useful signs for those seeking landfall since they provide a fairly specific direction to the seafarer. Observing the daily flight patterns of these birds can indicate the direction of islands far out of the range of sight.
When foraging for food for their young, it is estimated that manu-o-Kū may forage as far as 120 miles from land. In Hawaiian culture, some seabirds are often referred to as extensions of land because of their connection to islands.
The meaning of manu-o-Kū is often interpreted as “bird of Kū." Kū is one of the four major Hawaiian gods and is associated with diverse aspects of the Hawaiian universe such as governance, certain types of fishing and crop production, carving of canoes, long life, and family. Some of the meanings of the word kū that are also associated to the god Kū are upright, to rise up, or to establish. As reliable patrons of navigation and wayfinding, manu-o-Kū embody the energy of Kū and his concern for the governance and prosperity of a rising nation like an island from out of the sea.

The white ibis certainly "fits the bill" as one of the most common wading birds in NOAA Florida Keys National Marine Sanctuary. Their long, red bills are used to stir up and catch prey in the sanctuary's shallow waters. White ibises are usually followed by other wading birds that attempt to catch the scraps.

In 1980, Nainoa Thompson became the first Native Hawaiian in 600 years to use wayfinding – non-instrument navigation – to sail a traditional Hawaiian waʻa kaulua (double-hulled sailing canoe) to Tahiti and back. He learned this ancient skill from master navigator Mau Piailug of Satawal, Micronesia. The voyage of Hōkūleʻa and the crews that sailed it helped spark a renaissance of Hawaiian language and culture. Since then, Hōkūleʻa has sailed around the world, visiting over 150 ports across 18 nations to spread a message of Mālama Honua (caring for Island Earth). Nainoa and a small group of other master navigators continue to train new generations of wayfinders, using the islands of Nihoa and Mokumanamana in Papahānaumokuākea Marine National Monument as training grounds for apprentices readying themselves to lead crews on long, open ocean voyages beyond the Hawaiian archipelago.

The month of May is Asian American/Pacific Islander Heritage Month! In American Samoa, there is a mythological story called “Sina and the Eel” that tells the origin of the first coconut tree. Legend tells of a beautiful girl named Sina who befriended an eel. The eel grew large and fell in love with Sina, but this frightened her. The village chiefs saw her in anguish and rushed out to kill the eel. Before it died, the eel requested Sina to bury its head in the ground, and from its place, a “tree of life” known as the coconut tree would grow from it. This tree is the eel’s gift of love for her.
The coconut, with husks removed, has a facial resemblance of the eel, with its two eyes and a mouth. The legend suggests that by taking a drink from the coconut, it is a kiss for the eel. The coconut tree is a gift of life for the Samoan people. Every part of the tree is used in Samoan culture. It provides a source of food, shelter, clothing, cooking materials, and a wide range of useful products.

Whales, such as the humpback whale, are known as koholā in the Hawaiian language. They have long been revered for their connection to the native people of Hawai‘i and their history. Various oral traditions and written historical accounts describe the relationship between the early people of Hawaiʻi and koholā in Hawaiian waters and there are many other examples of this cultural heritage within legends, storied place names, and material culture. Here, a humpback whale swims in the warm waters of Hawaiian Islands Humpback Whale National Marine Sanctuary.

The fautasi (meaning “built as one”) is a traditional Samoan longboat canoe, sometimes up to 100 feet long! The fautasi is significant as a living maritime cultural tradition in American Samoa. Long ago, fautasi were used primarily in warfare to transfer cargo and supplies, and as a mode of inter island transportation. Today, fautasi racing is the highlight of the annual American Samoa Flag Day festivities in April, with support from the entire village that trains several months prior.

Tiger sharks are one of many shark (manō) species in Hawai‘i and are important members of the coastal ecosystem. As apex predators, they help keep marine ecosystems in balance by removing injured and sick animals. Manō are an important part of Native Hawaiian culture. They are found in many stories and songs, where they appear as guardians, villains, navigators, and healers.

Have you ever wondered about the name of Papahānaumokuākea Marine National Monument? The name of Papahānaumokuākea acknowledges two prominent Native Hawaiian ancestors: Papahānaumoku, the broad expansive earth who gives birth to islands through the oceanic womb, and Wākea, sky father, the broad expanse that allows us to access time and space. Naming the monument for Papahānaumoku and Wākea is an acknowledgment of the ancestral connections of people and place. Throughout the Pacific, other island cultures acknowledge Papahānaumoku and Wākea by other names such as Papatūānuku and Ranginui in Aotearoa (New Zealand) and Fakahotuhenua and Ātea in Tahiti. These similarities tell us about a common origin among distant places throughout the Pacific Islands connected by one ocean.
Pictured here is Nihoa, one of the Northwestern Hawaiian Islands protected within the monument.

May is Asian American/Pacific Islander Heritage Month! The National Marine Sanctuary System has a long history of working closely with communities in American Samoa and Hawai‘i, and all month we'll be featuring information and stories about these collaborations.
Today, say talofa–hello–to NOAA National Marine Sanctuary of American Samoa! The phrase Fa‘a Samoa is often heard in American Samoa and refers to the traditional Samoan way of life. It is the foundation of Polynesia’s oldest culture, dating back about 3,000 years. Just like Fa‘a Samoa places great importance on the collective rather than the individual, the sanctuary is a hub of collaboration, striving together to preserve and protect our special underwater treasures.

Our newest national marine sanctuary is Mallows Bay-Potomac River National Marine Sanctuary, located in Maryland's Potomac River. This site is most renowned for its “Ghost Fleet,” the partially submerged remains of more than 100 wooden steamships that were built in response to threats from World War I-era German U-boats that were sinking ships in the Atlantic. Today, in addition to serving as living museums, the shipwrecks serve as habitat for animals like ospreys.

I believe I can fly! This adorable little floof is a white tern chick. Also known as fairy terns, or manu-o-kū in Hawaiian, these small birds breed throughout Papahānaumokuākea Marine National Monument in the Northwestern Hawaiian Islands. They're one of the 22 species of seabirds that breed and nest in the monument. Unlike most other seabirds, adult white terns don't build a nest; instead, they find a suitable spot on a tree branch, rock ledge, or other surface and lay their egg there.

This photo of NOAA's Monterey Bay National Marine Sanctuary was taken with a GoPro that was launched to the edge of space via weather balloon. The balloon was launched from San Francisco, hit a maximum altitude of 91,470 feet, and landed in the Salinas Valley area. At this altitude, the camera is above 99.9% of the atmosphere, so it is able to capture the blackness of space above Earth's relatively thin atmosphere. Views like this remind us that Earth Is Blue

Today is the International Day of Forests – and did you know there are forests in the ocean? Kelp forests grow in many of your national marine sanctuaries along the West Coast, where they support lush, biodiverse communities. In NOAA's Monterey Bay National Marine Sanctuary, pictured here, giant kelp canopies tower above the ocean floor. Giant kelp can grow up to 18 inches per day! Among the many mammals and birds that use these forests as shelter or feeding grounds are seals, sea lions, whales, sea otters, gulls, cormorants, and more.

On the water? Always keep an eye out for whales! At least nine instances of humpback whale/vessel collisions have been reported since December in Hawaiian Islands Humpback Whale National Marine Sanctuary, and whales are also at risk of collisions in other national marine sanctuaries. With recent reports of whales – often young whales – showing propeller injuries, please remember to keep a safe distance. Collisions with vessels are a risk to both the animals and humans.
Boaters can help prevent collisions by posting a lookout at all times throughout the year, not just when whales are most prevalent. An extra set of eyes scanning the waters ahead and to the side of a boat can prevent collisions with marine life, obstructions, divers, and other vessels. Slow down, too: slower speeds may help you avoid hitting a whale or other animals.
If you come across an injured or entangled marine mammal, please maintain the required safe and legal distance and notify your local stranding network.

Earlier this year, the National Marine Sanctuary System lost one of the treasured members of our family, Greg McFall. The director of the NOAA Diving Program, Greg had also served as research coordinator and superintendent of NOAA Gray's Reef National Marine Sanctuary and supported many other national marine sanctuaries. His passing is a huge loss to us and to the larger sanctuaries community.
Whether you have been following us on social media for a few months or a few years, you likely came to know Greg through his photography. An accomplished diver and gifted photographer, Greg provided an unparalleled view of the underwater world from the Florida Keys to American Samoa. This week, in honor of his memory, we will be sharing some of his photographs across our social media. If you knew Greg or his photography, we would love to hear your memories.

Happy Seagrass Awareness Month! Let’s get down to the grass tacks: seagrass plays a vital role in supporting ocean ecosystems. A wide variety of animals, such as manatees, seahorses, and this shy scorpionfish in NOAA Florida Keys National Marine Sanctuary rely on seagrass for both food and shelter. Seagrass also produces oxygen, protects shores from powerful wave action, and makes water clearer. So put those lawnmowers away, this grass is way too important!

We’re feeling crabby about the invasive European green crab that has made its way into NOAA's Greater Farallones National Marine Sanctuary! This species first appeared along the Western U.S. in 1989, likely through the ballast water of cargo ships traveling across the ocean. These highly adaptable predators feast on shrimp, oysters, clams and small Dungeness crabs, taking away important food sources for local shorebirds and migratory seabirds. Since 2009 researchers from the Smithsonian Environmental Research Center, universities, and volunteers have been working to remove these crabs.

Asian kelp, or "wakame," is an invasive species of kelp native to Japan that has colonized harbors along the California coastline, including in NOAA's Greater Farallones National Marine Sanctuary and NOAA's Monterey Bay National Marine Sanctuary. Wakame colonizes ecosystems rapidly and densely. That can alter the habitat of native species by reducing the amount of light cover and and restricting water movement. Thanks to a little kelp from national marine sanctuary scientists and volunteers, wakame removal and research efforts are well underway! Studying wakame will help improve management practices of the invasive species while improving understanding of how it impacts local ecosystems.

What’s black, white, and dangerously strong? Zebra muscles – er, mussels! Zebra mussels are an invasive species in the Great Lakes, probably brought via ballast water discharged by large ships from Europe. These mussels take over hard surfaces such as buoys, docks, and submerged archaeological resources, including the shipwrecks in NOAA Thunder Bay National Marine Sanctuary. Zebra mussels’ presence on shipwrecks creates a significant challenge for archaeologists, historians, and resource managers, making it difficult for them to document wrecks over time. They also alter nutrient cycles and deplete the local food supply for native species.

In recent decades, Indo-Pacific lionfish have been found in coral reefs throughout the southeast Atlantic, Gulf of Mexico, and Caribbean – including in sanctuaries like NOAA's Flower Garden Banks National Marine Sanctuary. Because of their voracious appetites, rapid reproduction rate, and lack of natural predators, these invasive lionfish pose a serious threat to coral reefs, with potential long-term consequences for native fish communities, habitats, and entire ecosystems.

It's Invasive Species Week! All week long, we'll be bringing you information about invasive species and their effects on national marine sanctuaries. Though environments certainly change over time, invasive species can crowd out native species, shifting the balance and potentially damaging the ecosystem to which they've been introduced. Here, Dr. Steve Lonhart surveys an area of rocky reef in NOAA's Monterey Bay National Marine Sanctuary.

Deep sea research in national marine sanctuaries requires all eight hands on deck – at least for this octopus! Researchers aboard the E/V Nautilus spotted this octopus while diving on Davidson Seamount in NOAA's Monterey Bay National Marine Sanctuary last year. Those green dots in the upper left aren't spooky eyes looking out from the mud, but rather two lasers shined from the remotely operated vehicle Hercules. The lasers are mounted 10 centimeters apart from one another, and help researchers estimate the size of animals like this one.

Nap time! This sleepy friend in Hawaiian Islands Humpback Whale National Marine Sanctuary is a Hawaiian monk seal, which is unfortunately one of the most endangered species in the world. These seals face many threats, including limited food supply, entanglement, habitat loss, and human interaction. NOAA scientists are working to manage and conserve monk seal populations so that these adorable animals can continue to survive. If you see a Hawaiian monk seal, keep plenty of distance and report sightings to pifsc.monksealsighting@noaa.gov.

Nudibranch alert! This little beauty in NOAA Gray's Reef National Marine Sanctuary is a regal sea goddess. Nudibranchs are soft-bodied mollusks and are sometimes known as sea slugs. "Nudibranch" means "naked gills" – these mollusks carry their gills on their backs! There are many different species of nudibranch found all throughout national marine sanctuaries. What is your favorite kind to spot?

"For real? You think I'm cute? Aw, get otter here."
We're pawsitive that sea otters are one of the most adorable inhabitants of NOAA's Monterey Bay National Marine Sanctuary. Even though they look cuddly, though, make sure to give them plenty of space (pro tip: use a zoom lens or binoculars!). If you get too close, you might interrupt their feeding, grooming, and resting, which can negatively impact their health and make it harder for these adorable creatures to survive. With good ocean etiquette, you can help protect sea otters and other animals.

This North Atlantic right whale is splashing into World Whale Day! Today, we're celebrating these beautiful ocean giants.
North Atlantic right whales like this one in NOAA's Stellwagen Bank National Marine Sanctuary are one of the most highly endangered whale species in the world – only about 400 whales remain. They are threatened by entanglement in fishing gear and collisions with ships. There is good news, though: so far this season there have been 10 new calves sighted!
Photo: Peter Flood
When a whale dies at sea, its body becomes an oasis for other animals on the seafloor. After death, a whale's body will sink to the seafloor – and there, it can feed other organisms for years or even decades. On the seafloor, the whale carcass or skeleton is known as a whale fall. This past October, researchers on the E/V Nautilus were exploring Davidson Seamount in NOAA's Monterey Bay National Marine Sanctuary when they came across this whale fall at a depth of 10,623 feet. What animals can you spot on the whale fall?

Looking for a Valentine today? Try using echolocation! Toothed whales, like these orcas in NOAA's Monterey Bay National Marine Sanctuary, emit sounds that travel through the water and bounce off fish and marine mammals. They can use the sounds to create a mental map of where exactly things are! Sounds like a good way to locate a Valentine to us.

One of the biggest threats to humpback whales and other whales is entanglement in fishing gear and other debris. Entanglement can injure, starve, or drown whales. Fortunately, teams of intrepid individuals are on the scene to help whales like this one. Hawaiian Islands Humpback Whale National Marine Sanctuary leads the Hawaiian Islands Entanglement Response Network, a partnership of government agencies, tour operators, fishers, and more who work together to safely free whales. While of course everyone wants to help entangled whales, it is crucial that you never attempt to disentangle a whale yourself – it can be dangerous for both you and the whale. Instead, call your local stranding network so that trained professionals can help.

Meet Salt, the "grand dame" of NOAA's Stellwagen Bank National Marine Sanctuary. She was first spotted in Massachusetts Bay in the 1970s, and has been seen in the sanctuary just about every year since then. She has had 14 calves and many grandchildren, and at least one great-grandcalf! Salt was one of the first northern humpback whales to be recognized at Silver Bank off the coast of the Dominican Republic, providing proof of the humpback whale migratory route in the North Atlantic – which in turn has helped us better protect humpback whale populations through sister sanctuary relationships.

This sea otter in Elkhorn Slough is otterly thrilled that it's World Wetlands Day! Located in NOAA's Monterey Bay National Marine Sanctuary, Elkhorn Slough is one of California's last great coastal wetlands. Flushed by ocean tides in the heart of Monterey Bay, its waterways, mudflats, and marsh support a huge diversity of wildlife – including sea otters! Estuaries like Elkhorn Slough are extremely productive ecosystems, and provide food, shelter, migration stopovers, and places to breed for many animals. However, they're also quite delicate and need our help to ensure they remain thriving ecosystems.

"Whale...we're gonna need a bigger boat." These scientists in NOAA's Stellwagen Bank National Marine Sanctuary got a treat (or maybe a fright) when a humpback whale breached surprisingly close to them. Small boats like this one allow permitted researchers to get close enough to whales to attach tags with suction cups. The tags then give them a wealth of information about the whale's movements, feeding patterns, and more. If you're out on the water whale watching or just in an area with whales, make sure to give the marine mammals plenty of space!

Every winter, the beaches of NOAA's Monterey Bay National Marine Sanctuary and other sanctuaries along the West Coast transform into a mating ground for elephant seals. Males battle it out for territory in quick clashes that rarely result in lasting damage. Soon after, the females arrive to breed, and will spend a month on land raising their pups before voyaging back to the sea. Elephant seals are lots of fun to watch, but make sure to give them plenty of space – an elephant seal selfie is NOT a good idea! These huge seals can be dangerous, and when you get too close you can stress them during a critical time in their life.

The waters off North Carolina have claimed thousands of vessels over the years. Most of the shipwrecks near NOAA Monitor National Marine Sanctuary are from World War II's Battle of the Atlantic. U-352, for example, was a German U-boat intended to patrol the waters off the U.S. East Coast during the war. Instead, U-352 became the first U-boat sunk by the U.S. Coast Guard during the Battle of the Atlantic. Today, the wreck is a popular dive site for those interested in its history and the dense array of marine life.

Today is International Mountain Day – and did you know that there are mountains in the ocean? Seamounts are undersea mountains formed by volcanic activity, and they're typically biological hotspots. For example, on Davidson Seamount in NOAA's Monterey Bay National Marine Sanctuary, researchers with Nautilus Live encountered more than a thousand Muusoctopus octopuses tucked into nooks! Most of the octopuses had their arms inverted in a brooding posture. We love a good octopus garden, but we love an octopus garden on an ocean mountain even more!

Looking for a way to help corals stay healthy? Make sure you're using a reef-safe sunscreen or use Ultraviolet Protection Factor (UPF) sunwear! Several chemicals in traditional sunscreen can damage and kill corals, and are also harmful to green algae, sea urchins, fish, mussels, and dolphins. Even if you don't live near the ocean, when you shower, the chemicals in sunscreen may wash off and enter our waterways. So by making a small change in your sun protection, you can help support healthy coral reefs!

Who's that reaching out from the coral reef of NOAA's Flower Garden Banks National Marine Sanctuary? A sneaky brittle star! Every August, the reef-building corals within the sanctuary put on one of the most abundant spawning displays in the entire Caribbean and Gulf of Mexico. Each coral species times its gamete (egg and sperm) release to ensure genetic mixing and that coral larvae can disperse over large distances. The gametes also provide a feast for small animals like this brittle star.

What's wrong with this picture? These two images show a reef in NOAA National Marine Sanctuary of American Samoa just months before (left) and after (right) a bleaching event. When we burn energy sources like gasoline and coal, we release carbon dioxide into the atmosphere. This carbon dioxide acts like a heat-trapping blanket, keeping heat from the sun close to the planet and warming the atmosphere and the ocean. Corals are sensitive to temperature: if the water gets too warm, they expel the colorful algae that they need to survive. This is called bleaching, and if it lasts long enough, the corals can die. But there are things we can do: by working with your community to curb your fossil fuel consumption and reduce other coral stressors, like pollution, you can help protect vibrant coral reefs!

Did you know there are corals in the deep ocean? It's true! Many species of coral thrive in the deep sea, like this Swiftia coral in NOAA's Cordell Bank National Marine Sanctuary. The corals position themselves so they can grasp small particles of food from the current, and also provide habitat for other animals like these brittle stars. What other deep-sea dwellers can you spot here?

Happy birthday to NOAA's Stellwagen Bank National Marine Sanctuary and Hawaiian Islands Humpback Whale National Marine Sanctuary! Though thousands of miles apart, both of these sanctuaries offer refuge to humpback whales. Each summer, humpback whales migrate from the Caribbean to Stellwagen Bank off the coast of Cape Cod, Massachusetts, where they and other whales feast on the food that flourishes in sanctuary waters. And in the Pacific, humpback whales journey to the warm waters surrounding the Hawaiian Islands each winter to mate, calve, and raise their young.

Sing it with us (and this humpback whale): Happy birthday to the Marine Mammal Protection Act! Enacted on this day in 1972, this important piece of legislation helps us protect animals like this humpback whale in NOAA's Stellwagen Bank National Marine Sanctuary. The act ensures that marine mammals like whales, porpoises, seals, sea lions, otters, and dolphins can carry out their normal lives without disruption – and without the threat of hunting, poaching, or exploitation.

Citizen science isn't just for people anymore! This Muusoctopus octopus hopped aboard Nautilus Live's ROV Hercules last week to get a better look. Hercules was exploring a whale fall in NOAA's Monterey Bay National Marine Sanctuarythat was being scavenged by octopuses, fish, and other animals. The octopus crawled along Hercules' sampling vessels before presumably going back to eat some more. A whale fall – the carcass of a whale that has sunk to the seafloor – can feed communities of organisms for months or years.

Scientists aboard the E/V Nautilus got a treat yesterday when they came across a whale fall in NOAA's Monterey Bay National Marine Sanctuary! When whales die at sea, they sink to the seafloor where they can feed other organisms for years. There, the whale carcass or skeleton is known as a whale fall. The Nautilus Live team found this whale fall at a depth of 10,623 feet while exploring Davidson Seamount, an underwater mountain. The whale skeleton is lying on its back and is an estimated 13 to 16 feet in length. The team is working to identify the species, but it is confirmed to be a baleen whale. Look closely and you can see Muusoctopus octopuses and other marine animals!

We're not squidding around when we say we love cephalopods! Photographer Alexander Neufeld describes his encounter with this beautiful reef squid in NOAA Florida Keys National Marine Sanctuary this way: "A reef squid in the black waters off of Key Largo during a night dive. Several squid joined us during a portion of the dive, hovering just below the surface, which allowed for the reflection of the squid's body in the final image. Once the squid had enough of us, it took off in a cloud of ink."

Meet the giant clam, also known as faisua in Samoan! These beautiful clams can be spotted in the coral reefs of NOAA National Marine Sanctuary of American Samoa. Once nestled into a location on the reef, a giant clam will remain stationary throughout its life. Like corals, giant clams have developed symbiotic partnerships with algae called zooxanthellae. In return for shelter, zooxanthellae provide giant clams with nutrients they've photosynthesized – and help give the clam's mantle its pretty colors.

These American white pelicans are celebrating Estuaries Week in style! Estuaries are locations where rivers meet the sea. Located in NOAA's Monterey Bay National Marine Sanctuary, Elkhorn Slough is one of California's great estuaries. Flushed by ocean tides in the heart of Monterey Bay, its waterways, mudflats, and marsh support a huge diversity of wildlife. Estuaries like Elkhorn Slough provide food, shelter, migration stopovers, and places to breed for many animals. However, they're also quite delicate and need our help to ensure they remain thriving ecosystems. Learn more about estuaries and how you can support them.

What happens to trash after it flows down a creek or falls off a vessel at sea? Usually, it stays in the ocean for a long, long time. There, it can choke animals who mistake it for food, or entangle animals and drown them. This huge conglomeration of fishing nets and other trash was removed from French Frigate Shoals in Papahānaumokuākea Marine National Monument by NOAA Marine Debris and partners. Since 1996, they have removed 1017 tons of debris the remote expanses of the Northwestern Hawaiian Islands, which is about the same weight as nine blue whales! You can help keep debris out of the sea by participating in a cleanup this weekend for the International Coastal Cleanup, or any other day of the year.

Eyes of a hawk, and ears of a...fish?
Stocky hawkfish are known as po‘opa‘a in Hawaiian. In the coral reefs of Papahānaumokuākea Marine National Monument, they linger atop corals and survey their surroundings for prey, much like their terrestrial namesake. As an added level of protection, a stocky hawkfish’s pectoral fins are resistant to the stinging cells of fire corals, which normally harm other organisms upon contact. Well played, hawkfish. Well played.

Nothing hits the spot like a midday nap, especially for sea otters! Due to their high metabolism, sea otters – like this one in NOAA's Monterey Bay National Marine Sanctuary – have to eat and rest a lot as part of their daily routine. As otterly adorable as they are, it’s important to keep a safe viewing distance when coming across a sea otter in the wild so you don't interrupt the time they need to take care of themselves. Keep sea otters safe and undisturbed by respecting their space, and their naps!

It’s important to keep a safe viewing distance to make sure the wildlife aren’t disturbed by our admiration. In Hawai’i, whales cannot be approached closer than 100 yards, which protects humpback whales and whale watchers alike.

Animal or plant? Both the feathery object and the coils in this photo may look like plants (or something otherworldly) but they're actually animals! Researchers from the Global Foundation for Ocean Exploration and NOAA's Flower Garden Banks National Marine Sanctuary witnessed this reef at Alderdice Bank in the Gulf of Mexico. The feathery creature is a feather black coral, while the coils are known as sea whip corals. Both feed on plankton that is swept by in the current!
This photo is from an ongoing expedition that is livestreaming dives from areas in and around Flower Garden Banks National Marine Sanctuary. Tune in and learn more.

Keep your friends close, and your anemones further away! Sea anemones – like this one found in NOAA Florida Keys National Marine Sanctuary – are close relatives of coral and jellyfish. While their brightly colored tentacles are a beautiful sight, they are actually venomous and are used for capturing prey. Most species are benign to humans, but keeping your hands to yourself protects both you and the animal. Don't make an enemy of a sea anemone!

NOAA Florida Keys National Marine Sanctuary protects one of the most iconic ocean places in the world. But these important ocean habitats are in jeopardy of being “loved to death.” To survive for future generations, the Keys need to change, and there’s no time to lose. The sanctuary is proposing a new Restoration Blueprint, and we want to hear from you.

Now presenting the rosy palace of Rose Atoll, located in NOAA National Marine Sanctuary of American Samoa! The reef at Rose Atoll gets its pink hues from crustose coralline algae, an unassuming friend of the coral reef ecosystem. While corals lay down their own stony skeleton, crustose coralline algae crust over and between the structures to help cement them together, forming a reef. Can you name a more iconic duo?

We have an announcement: we've decided that this Facebook account will now be a succulent appreciation account.
Just kidding! This isn't a plant – it's a white-lined nudibranch. Nudibranchs, like this one found in NOAA's Monterey Bay National Marine Sanctuary, are sea slugs that often come in striking colors and forms. While they may look like they're making a fashion statement, nudibranchs often depend on their brilliant colors as defense from predators.

We’re a big fan of deep-sea fans! This fan coral and its fish friends were found at a depth of about 100 meters in the Santa Cruz Canyon, part of NOAA Channel Islands National Marine Sanctuary. Unlike their shallow-water relatives, deep sea corals don’t need sunlight to thrive; instead, they obtain energy and nutrients by trapping tiny organisms that pass through the water. Pretty fan-tastic if you ask us!

A day octopus – or he’e mauli in Hawaiian – sits pretty at French Frigate Shoals in Papahānaumokuākea Marine National Monument. Many cephalopods have special cells in their skin tissue called chromatophores that enable them to change color very rapidly. A part of their neuromuscular system, these cells receive signals from the environment that an octopus can use to inform color change. Octopodes of this particular species can change color almost instantly as they move over their environment, making them nearly invisible to predators!

For World Lion Day, we're bringing you the lions of the sea: Indo Pacific lionfish. As their name suggests, these fish are native to the Indo Pacific region, and are part of the food web in coral reefs in that area. In recent decades, though, these fish have been found in coral reefs throughout the southeast Atlantic, Gulf of Mexico, and Caribbean – including in NOAA Gray's Reef National Marine Sanctuary, NOAA's Flower Garden Banks National Marine Sanctuary, NOAA Florida Keys National Marine Sanctuary, and NOAA Monitor National Marine Sanctuary. Experts speculate that people have been dumping unwanted lionfish into the ocean for the last 25 years or more.
In their newfound habitats, lionfish don't have natural predators – plus, they have voracious appetites and reproduce quickly. This may spell trouble for biodiversity in coral reefs. a group of 1,000 lionfish can consume 5 million prey fish in a single year! NOAA and our partners are working to understand and control this invasive species with new traps, lionfish derbies, and more. You can help by asking restaurants near you to serve lionfish, and learn more here.

Sometimes it can be hard for maritime archaeologists to document shipwrecks because of all the fish! Here, NOAA Monitor National Marine Sanctuary archaeologist Will Sassorossi and NOAA Ship Nancy Foster's navigation officer ENS Sara Thompson explore the shipwreck of the USS Schurz, which sank during World War I off the coast of North Carolina. Shipwrecks like the USS Schurz have a second life beneath the waves as artificial reefs. Invertebrates like anemones and corals may attach to the wreck surface, while fish like the many seen here shelter and feed around the wreck.

How important is water quality to our marine and freshwater ecosystems? Important enough that we dedicate a month to celebrate it! August is National Water Quality Month. Our national marine sanctuaries depend on clean water to ensure that biological diversity, coastal scenery, and recreational and commercial opportunities thrive. During “Snapshot Day” in NOAA's Monterey Bay National Marine Sanctuary, hundreds of citizen science volunteers aid in water quality efforts, assessing rivers, streams, and other coastal California watersheds.

Ever wonder what it might be like to have a sixth sense? Sharks have that covered! Specialized organs called ampullae of Lorenzini help these stealthy hunters detect small electrical fields released by other animals. That way, sharks can sense their prey even if it's buried in the sand or in murky water. Hammerhead sharks – like this one in NOAA Gray's Reef National Marine Sanctuary – have an especially large number of these ampullae on their broad head.

Mirror mirror on the wall, who’s the sleepiest shark of them all?
Nurse sharks! These nocturnal bottom dwellers prefer to take it easy during daylight hours in caves and dark crevices. At night, nurse sharks scout the seafloor for crustaceans, mollusks, and other low-lying prey. This one was spotted in NOAA Florida Keys National Marine Sanctuary.
Bonus points if you can spot the eel hanging out near this shark!

This Laysan albatross, or mōlī, in Papahānaumokuākea Marine National Monument is in for a surprise. Tiger sharks like this one are voracious predators, much like their terrestrial namesake, and are known to take a bite out of just about anything that catches their attention. Though they can be frightening, sharks like the tiger shark are incredibly important animals in ocean environments. Sharks help remove dead or decaying debris from the ocean, and thereby help keep our ocean clean, while also helping to keep ecosystems in balance.

Happy Shark Awareness Day! Whale sharks are the biggest shark – and the biggest fish – in the ocean. These massive sharks are filter feeders, consuming tiny zooplankton. Like many shark species, whale sharks have hundreds of teeth, but theirs are tiny, pointed backwards, and thought to have no role at all in feeding. Lucky divers can spot these gentle giants in NOAA's Flower Garden Banks National Marine Sanctuary.

Each year, literal tons of garbage washes up on the shores of the Northwestern Hawaiian Islands in Papahānaumokuākea Marine National Monument. There, it threatens animals including juvenile Laysan albatross, who may eat plastic pieces or get entangled in derelict fishing nets.

Trash and animals don't mix well! Do you know what to do if you spot a marine mammal in distress?
First off, don't try to approach or disentangle the animal yourself. Wild animals – especially scared ones – can be volatile, and may injure you or themselves. Instead, contact your local stranding network so that trained professionals can safely help the animal in distress. If you're in Monterey Bay National Marine Sanctuary, where this fur seal was spotted, contact The Marine Mammal Center hotline (San Francisco Bay Area: 415-289-7325; Monterey or Santa Cruz Counties: 831-633-6298; San Luis Obispo County: 805-771-8300).

Ever wondered what paradise looks like? Well look no further! The beaches and coasts of NOAA National Marine Sanctuary of American Samoa are truly a sight to sea. However, marine debris not only threatens the diverse wildlife protected by the sanctuary, but it can also be an eyesore for those who admire these beautiful and culturally-significant landscapes. When celebrating Independence Day, keep in mind that trash travels! You can help preserve our national marine sanctuaries by cleaning up after yourself and encouraging those around you to do the same.
Photo: Greg McFall/NOAA
Bereef it or not, every year around 8 million metric tons of plastic make their way into our ocean! Trash that is left behind on shores and beaches are often swept into the ocean by high tides and wind, and can travel thousands of miles once it enters the water. Even deep ecosystems far from shore, like this one in NOAA's Cordell Bank National Marine Sanctuary, can be impacted plastic pollution. If you're visiting a beach this week for the Fourth of July, help keep our ocean clean and reefs healthy by joining a beach clean up, or take the lead and organize one!

Don’t be in breach of ocean etiquette! This week, we’ll be celebrating the red, white, and blue with Clean Beaches Week to protect and preserve our ocean and Great Lakes and all of their inhabitants, such as the humpback whales of NOAA's Stellwagen Bank National Marine Sanctuary. Due to their feeding methods, whales and other cetaceans are vulnerable to encounters with marine plastic floating through their habitats. By keeping our beaches trash free and leaving no trace behind when we enjoy our shores, we’re also helping protect marine life down the line!

Whale you know what they say, the best things in life come when you’re not looking for them! That’s exactly what happened with whale watchers in NOAA's Monterey Bay National Marine Sanctuary recently when they had some surprise visitors.

A fairy is among us! A fairy tern chick, that is. Known as manu-o-kū in Hawaiian, fairy terns are native to the Northwestern Hawaiian Islands, including Papahānaumokuākea Marine National Monument. Unlike most seabirds, fairy terns lay their eggs directly onto a surface like a tree branch or cliff ledge, rather than building a traditional nest! When the chicks hatch, they use their sturdy claws to grip onto the surface, which helps them weather even the strongest winds and storms.

Sink into some maritime history with NOAA Monitor National Marine Sanctuary! The USS Monitor, pictured here, was the first ironclad warship in the Union army. In 1862 in the throes of the Civil War, Monitor led the Union into battle against the Confederate ironclad CSS Virginia at the Battle of Hampton Roads. While the battle ultimately resulted in a draw, it marked the end of an era for wooden warships! Later that year, the USS Monitor met its fateful end off the coast of North Carolina during a treacherous storm, along with 16 brave members of its crew. Over a century later when the shipwreck was discovered, Monitor National Marine Sanctuary was designated as the first national marine sanctuary in the United States to protect our maritime heritage.

When gray seals and other seals hang out in the water upright like this one, they're said to be "bottling." Gray seals are often spotted within NOAA's Stellwagen Bank National Marine Sanctuary, where – between rests – they feed on fish, crustaceans, squid, and sometimes even small seabirds. While gray seals may appear approachable in the wild, human interference is a major threat to these marine mammals. Fishing entanglements, watercraft strikes, and interactions with humans put them at risk. Help protect gray seals by keeping a safe distance and not approaching them too close on land or on water.

Wisdom might get all the attention for being the world’s oldest known banded bird that has raised around 35 chicks in her lifetime (and counting!), but have you met her equally dedicated mate, Akeakamai?
Each year since 2006, Akeakamai, a Laysan albatross, has returned to Midway Atoll in Papahānaumokuākea Marine National Monument with his mate Wisdom to raise a chick. Over the course of several months, both parents take turns incubating the egg. When they’re not on parenting duty, they forage for food. Once the egg hatches, both parents spend another 5 to 6 months raising the chick before it leaves the island. Happy Father's Day to Akeakamai and all the dedicated dads out there!

Aaaand lift-off! Albatrosses like this black-footed albatross are long-distance travelers, migrating between their feeding and nesting grounds. This particular albatross was spotted in NOAA's Monterey Bay National Marine Sanctuary by Robert Schwemmer, our West Coast Region maritime heritage coordinator, and is special because of that little bit of green you see on its leg. That's a bird band, a small tag used to identify individual birds. Thanks to Schwemmer's zoom lens, we were able to read the number on this one and match it in the U.S. Geological Survey (USGS) database.
This particular albatross was originally banded May 30, 2002 – nearly 17 years ago – when it was too young to fly. It was banded in French Frigate Shoals in what is now part of Papahānaumokuākea Marine National Monument, more than 2,700 miles away from where it was spotted in Monterey Bay! Its band can help researchers track its journey and better understand the life cycle and ecological needs of black-footed albatrosses.
