Manatee are "gentle giants", whose greatest natural enemy, is man. Curious manatee are often injured by boat propellers. LeVar Burton speaks with the professionals who work with injured sea cows, and gets up-close with the manatee. Like all other mammals, the sea cow has hair covering its body.

Manatee have tiny valves protecting their nostrils, as they graze on vegetation under water. Sea Cows return to the surface every 3 to 5 minutes to breathe.

And.. like elephants, Manatee have toe nails on their flippers.


Some of them have even lost their toe nails, and developed smooth paddles like Cetaceans.

"The smallest member of the family Trichechidae, the Amazonian manatee has smooth skin and no nails on its flippers and feeds on freshwater vegetation."
