Otters are playful and social animals that belong to the weasel family. They are known for their sleek bodies, webbed feet, and thick fur, which keeps them warm in cold water. Otters can be found in rivers, lakes, and coastal areas around the world. They are excellent swimmers and often use tools, like rocks, to crack open shellfish. These charming creatures are also known for their playful behavior, often seen sliding down mud or snowbanks. Otters live in groups called rafts, where they groom each other and play together. Their friendly nature and adorable antics make them a favorite among wildlife enthusiasts.
