A large aquatic mammal (manatee).

This is a slow-moving mammal with a rounded body, gray to brown skin with fine sparse hair, small head, squarish snout with a deeply split upper lip, valvular nostrils, small eyes, flexible flippers, and a large rounded horizontally flattened tail. Adults usually are about 10-13 feet (300-400 cm) in total length. Newborn calves are about 3-4 feet (1 meter) long (Nowak 1991).
