Its body length ranges from 26 to 42 inches. About one-third of the animal’s total length consists of a long, tapered tail. Tail lengths range from 12 to 20 inches.

A broad muzzle is found on the American river otter’s or Lontra canadensis flat head, and the ears are round and inconspicuous. The nose is bare, with an obtuse, triangular projection.

Eyes are small and dark brown. A short, broad rostrum for exhaling and a long, broad cranium define the relatively flat skull.

The North American river otter’s or Lontra canadensis nostrils and ears close during submersion, keeping water from entering them. Its whiskers are long and thick, enhancing sensory perception underwater and on land.
