Coypu In turn, these two taxa share evolutionary affinities with other Myocastorini genera: "Proechimys" and "Hoplomys" (armored rats) on the one hand, and "Thrichomys" on the other hand. The coypu somewhat resembles a very large rat, or a beaver with a small tail. Adults are typically in weight, and in body length, with a 30 to 45 cm (12 to 18 in) tail. It is possible for coypu to weigh up to , although adults usually average . They have coarse, darkish brown outer fur with soft dense grey under fur, also called the nutria.
