Ranging over much of North America, the river otter 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.
