The United States is only home to two species of otters 鈥� the sea otter and the North American river otter 鈥� 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, .
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!
