Due to similar cranial morphology, the nutria was once considered a close relative of the Caribbean hutias and placed together with them in the family Capromyidae. [1] Later, it was more accepted to place it in its own family, the Myocastoridae. [2] Recent molecular studies place them in the family Echimyidae, in the tribe Myocastorini. [3] [4] [5]
The muskrat is much smaller than a beaver (Castor canadensis), with which they often share a habitat. [6] [7] Muskrats are covered with short, thick fur, which is medium to dark brown or black, with the belly a bit lighter (countershaded); as the animal ages, it turns partly gray. The fur has two layers, which protect it from cold water.
