Otters are playful and social animals that belong to the family Mustelidae. They are often found in rivers, lakes, and coastal areas, where they thrive in both freshwater and saltwater environments. Known for their sleek bodies and webbed feet, otters are excellent swimmers. They use their sharp claws to catch fish, crabs, and other small creatures, often floating on their backs while eating. These furry creatures are also famous for their playful behavior. Otters enjoy sliding down mud or snowbanks and playing with each other in the water. They are known to use tools, like rocks, to crack open shells, showcasing their intelligence and adaptability in the wild.
