coypu

a large chestnut brown, 14 inch long and 15 lb in weight, aquatic rodent which is farmed extensively for its fur. It is herbivorous, diurnal and very fertile. As a wild animal in countries where it has escaped, it has become a pest. Called also nutria, Myocastor coypus, swamp beaver.

The Myocastor genus belongs to the mammalian Order Rodentia based on morphological features common to the group, particularly dental features (Nowak 1991).
Of the species likely to occur in the region (see Kennedy, 1991), only the swamp rabbit (Sylvilagus aquaticus), woodchuck (Marmota monax), coypu (nutria; Myocastor coypus) and long-tailed weasel (Mustela frenata) were not verified on the Park during the present study.
