November is Manatee Awareness Month; but no matter what time of year it is, manatees deserve to be celebrated. These amazing creatures fulfill a unique niche by serving as indicator species for ecosystems across the United States. Because of their reliance on the health of their habitat, manatees often act as a signal of their environment’s well-being. NOAA photo by Michael Buchanan.
