This aquatic member of the weasel family is found along the coasts of the Pacific Ocean in North America and Asia. The sea otter spends most of its time in the water but, in some locations, comes ashore to sleep or rest. Sea otters have webbed feet, water-repellent fur to keep them dry and warm, and nostrils and ears that close in the water.

An endangered species, the adult sea otter is the smallest of the marine mammals. It's a member of the weasel family, and the only marine mammal that doesn't have blubber to keep it warm. Instead the sea otter relies on its thick fur to keep its body temperature around 100 degrees.
