Manatees
One of the strangest looking ocean mammals is the manatee. To make it even more unusual, a manatee is not related to any other ocean mammal but is a distant cousin of the elephant. The manatee and elephant even have physical features that are similar. Both mammals are the same gray color with short wiry hair. Manatees have toenails like an elephant and even have a short trunk. Scientists believe that manatees evolved millions of years ago from land to marine animals leaving their much larger cousin the elephant behind. Like other marine animals a manatee, which is sometimes called a sea cow, has to surface to breathe.
