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. Fast Facts Length: 10-12 feet. Weight: 1,500-1,800 lbs. Lifespan: 50-60 years in the wild. Diet Manatees are herbivores; they eat marine and freshwater plants. Population The largest population of manatees is found in Florida, where there are over 3,000 individuals. Did You Know? Manatees only have molars, which are used to grind food. As they wear down and fall out, they are replaced with new teeth. 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. Did You Know? Manatees only breathe through their nostrils, since while they are underwater their mouths are occupied with eating!. Manatee lungs are 2/3 the length of its body. Reproduction Mating 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. Climate Change and Other Threats Since manatees spend their live in the water, climate change poses significant threats to their well-being. Higher water temperatures along the Gulf Coast has lead to an increase in toxic algae blooms, such as the red tide that killed more than 150 manatees in 1996. Global warming also raises the odds against these already endangered creatures by increasing the likelihood of larger and more frequent hurricanes. Did You Know? The closest living relatives to the manatee include the elephant and the hyrax. Other threats to manatees include 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 also 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 West Indian manatees in the United States are protected under federal law by the Marine Mammal Protection Act of 1972 which make it illegal to harass, hunt, capture, or kill any marine mammal. West Indian manatees are also protected by the Florida Manatee Sanctuary Act of 1978. Violations of these federal or state laws can be met with civil or criminal convictions associated with monetary fines and/or imprisonment. Endangered Species Act (ESA): The manatee is listed as endangered.
