The United States is only home to two species of otters — the sea otter and the North American river otter — but about 90 percent of all the world's sea otters live in Alaska. They are protected by the Marine Mammal Protection Act and the Endangered Species Act, according to the U.S. Department of the Interior.
These cuddly cuties have extra thick fur which keeps them warm and helps them float. Because of this, otters spend a long time each day taking care of their fur. Baby otters have such dense fur that they are able to float before they even learn to swim!
