The American river otter is a graceful and beautiful addition to many North Carolina rivers. Sighting one can be an exciting occasion for boaters, fishermen and other outdoor enthusiasts because of the creature’s secretive nature and relative rarity in some waters. The animal slides down mud and snow seemingly for the sheer delight of it. Otters are found on every continent except Australia and Antarctica. There are seven recognized subspecies of the American river otter.

​

The small eyes and ears are located high on the head for surface swimming and the whiskers are highly sensitive to aid in the capture of prey in murky water or on dark nights. Otters’ nearsightedness may be an adaptation to improve underwater vision. The otter’s feet have five toes with nonretractable claws and webbing between each toe. The heel pads on the hind feet are adapted to provide better traction on slippery surfaces. The waterproof fur is short and dense. It is generally dark brown with light brown coloring under the neck, chest and stomach. Otters are excellent swimmers and are able to swim forward or backward. They often tread water to look and listen to their surroundings.
