Florida Manatee
Trichechus manatus latirostrus
The florida manatee, Florida’s state marine mammal, is a large aquatic relative of the elephant. They are grayish brown in color and have thick, wrinkled skin on which there is often a growth of algae. Their front flippers help them steer or sometimes crawl through shallow water. They also have powerful flat tails that help propel them through the water. Despite their small eyes and lack of outer ears, manatees are thought to see and hear quite well.
Length 10-12 feet
Weight 1,500-1,800 lbs
Diet
Herbivores: they eat marine and freshwater plants.
Population
The largest population of manatees is found in Florida, where there are over 3,000 individuals.
Range
Manatees take up residence primarily in Florida’s coastal waters during winter. Some individuals migrate as far north as the Carolinas or as far west as Louisiana in summer. In recent years, a manatee traveled to New York and another swam up the Mississippi River!
Behavior
Manatees can be found in the warm waters of shallow rivers, bays, estuaries and coastal waters. Rarely do individuals venture into waters that are below 68 degrees Fahrenheit. Well known for their gentle, slow-moving nature, manatees have also been known to body surf or barrel roll when playing. They normally rest and feed often. Manatees communicate by squealing under water to demonstrate fear, stress or excitement.
ReproductionMating Season No specific period
Gestation About 1 year
Number of offspring 1 calf
Calves are born weighing between 60 and 70 pounds and measuring about 3-4 feet. They nurse underwater.
Threats
Destruction and degradation of their coastal and freshwater habitat. The leading known cause of death is by boat strikes; propellers and hulls inflict serious or mortal wounds. Most manatees have a pattern of scars on their backs or tails after surviving collisions with boats. Scientists use these patterns to identify individuals. Manatees are also vulnerable to cold water. They have been found crushed or drowned in flood-control gates and suffer harm from exposure to toxic red tide. In addition, a large number of manatees die from unknown causes each year.
Legal Status/Protection
Federally listed as Endangered and state listed as Endangered. *Endangered Species Act; **Marine Mammal Protection Act; Florida Endangered and Threatened Species Act; Florida Administrative Code; Florida Marine Sanctuary Act; ***CITES Appendix 1.
* The Endangered Species Act requires the US federal government to identify species threatened with extinction, identify habitat they need to survive, and help protect both. In doing so, the Act works to ensure the basic health of our natural ecosystems and protect the legacy of conservation we leave to our children and grandchildren.
** The Marine Mammal Protection Act prohibits, with certain exceptions, the take of marine mammals in U.S. waters and by U.S. citizens on the high seas, and the importation of marine mammals and marine mammal products into the U.S.
*** Convention on International Trade in Endangered Species of Wild Fauna and Flora, an international treaty with 172 member countries. Appendix I species cannot be traded commercially. Appendix II species can be traded commercially only if it does not harm their survival.
