North American river otters, also called Canadian otters, have long, muscular, streamlined bodies with short legs and fully webbed feet bearing non-retractable claws. Their small heads widen to long necks and shoulders, and they have flattened, well-muscled tails. These otters have brown-to-gray fur, and their undersides are a lighter, silvery shade.
Their dense, short under-fur is overlain by darker, coarse guard hairs that help repel water. The river otter's eyes and ears are located high on its head for surface swimming. A third eyelid, or nictitating membrane, protects the eye and allows the otter to see when swimming underwater. The otter's ears and nostrils close underwater. River otters have long, stiff and highly sensitive facial whiskers that aid in locating and capturing prey. The otters typically capture prey in their mouths but occasionally use their thumbs and forepaws to grasp and manipulate prey.
Like other carnivores, their teeth are well adapted for grinding and crushing. River otters use their powerful hind feet to help with propulsion and their small, dexterous front feet for paddling through the water. Adult river otters weigh 10 to 33 pounds 4. Females are roughly one-third the size of males.
River otters are found throughout most of North America from the Rio Grande to Canada and Alaska, except for in arid deserts and the treeless Arctic. They live in riparian zones, often in the same areas as beavers. Their aquatic habitats can be both marine and fresh water: streams, rivers, lakes, ponds and marshes. They prefer unpolluted water with a minimal human disturbance. An extremely adaptable animal, otters tolerate hot and cold climates, as well as high elevations and lowland coastal waters. When threatened or frightened, they emit a hair-raising scream that can be heard up to 1.
River otters leave scent marks on vegetation within their home range. River otters eat mostly aquatic organisms, including fish, frogs, crayfish, turtles, insects and some small mammals. North American river otters get their boundless energy from their very high metabolism, which also requires that they eat a great deal during the day. At the Smithsonian's National Zoo, they eat a prepared meat diet and several types of fish. They also receive mice, carrots, hard-boiled eggs, clams, crayfish, dry kibble, crickets and live fish for variety and enrichment.
