Have you seen an otter?
River otters are semi-aquatic members of the weasel family. Some of their defining features include:
Long, torpedo-shaped bodies
Short legs
A short snout
Small, round ears
Light to dark brown fur that can appear almost black when wet, and a silver-brown underbelly
Weight between 15 and 25 lbs
Length of 3 to 4 1/2 feet from their nose to the tip of their long furry, cylindrical tail
A thick, muscular tail that tapers toward the tip, and comprises about one-third of their total length at 12-17 inches
Several Colorado mammals, including mink, beaver and muskrats, share the same habitat as river otters and are commonly confused with otters. All have dark brown fur and can be particularly difficult to distinguish from each other when they are swimming on the surface, partially submerged, especially when viewed from a distance. When viewed on land, however, their body shape, weight, size and tails are all quite distinctive.
