Sea otters are small, playful marine mammals with long bodies and webbed paws. They are related to land animals like weasels and minks but spend most of their time in cold water, protected by their thick fur. Sea otters are known for floating on their backs, playing, and using rocks as tools to open mollusks. They groom each other and rest in groups called rafts, holding hands to stay together.
