Manatees are gentle and slow-moving; most of their time is spent eating 100 to 150 pounds of vegetation per day. Nicknamed the sea cow, the manatee is a mammal similar in size to a small whale, its natural habitat is off the coast of Florida. During the winter months, the large creatures spend time near natural warm springs. Newscom/File
