Manatees range in color from gray to brown. They use their two small front flippers to crawl along ocean or river bottoms. Their flat, horizontal tails are pumped up and down to move them along. Despite their small eyes and lack of outer ears, manatees are thought to see and hear quite well.

One of the closest surviving relatives of the manatee is the elephant. Manatees have many anatomical parallels with elephants, including a long, flexible nose or trunk, whiskers, and toenails.

The average adult manatee weighs 1,500 to 1,800 pounds and measures ten to 12 feet in length. The largest population of manatees is found in Florida, where over 5,000 individuals now live. Manatees are thought to live 50 to 60 years in the wild.

Manatees take up residence primarily in Florida’s coastal waters during winter and migrate either as far north as the Carolinas or as far west as Louisiana during the summer months. Manatees inhabit the shallow, marshy coastal areas and rivers of the Caribbean Sea and the Gulf of Mexico (T. manatus, West Indian Manatee), the Amazon Basin (T. inunguis, Amazonian Manatee), and West Africa (T. senegalensis, West African Manatee). West Indian Manatees enjoy warmer waters and are known to congregate in shallow waters, and frequently migrate through brackish water estuaries to freshwater springs. Their natural source for warmth during winter is warm, spring fed rivers.

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. Manatees often congregate near power plants, which warm the waters. Some have become reliant on this source of unnatural heat and have ceased migrating to warmer waters. Manatees are herbivores and eat marine and freshwater plants.

Well known for their gentle, slow-moving nature, manatees have also been known to body surf or barrel roll when playing. Normally they rest and feed often. Manatees communicate by squealing under water to demonstrate fear, stress or excitement. They emit a wide range of sounds used in communication, especially between cows and their calves. Adults communicate to maintain contact and during sexual and play behaviors. Taste and smell, in addition to sight, sound, and touch, may also be forms of communication.
