Why Sea Otters get cold in the water?

Sea otters do not get cold. Sea otters are very well adapted to live in the cold waters of the ocean. They have a thick layer of fur that helps keep them warm, and their body fat helps to insulate them. Sea otters also have an increased metabolic rate, which allows them to generate more heat. Finally, they spend a significant amount of time grooming their fur, which helps it stay water-resistant and buoyant.
