Ranging over much of North America, the North American river otter (Lutra canadensis) survives anywhere with access to abundant prey and clean water. With a streamlined body, webbed feet, muscular tail, flexible body, and waterproof fur, otters are designed for swimming in search of fish, crayfish, and other aquatic creatures to eat. Otters den in a riverbank burrow, under a rock pile, in a thicket, or even in another animal’s home such as a beaver’s lodge.
The river otter is famous for its playful antics – mud sliding, water sports and manipulating objects – which increases coordination and sharpens hunting skills.
