Nutria also breed rapidly: Females first become pregnant around six months old, and can have four litters a year of between six and 12 pups per litter. Add that to the fact that, as a South American import, the nutria have no natural predators in the area, and the region has one troublesome rodent species on its hands.
General Description. The nutria is a large, light- to (typically) dark-brown, fur-bearing rodent that spends the majority of its time in or near water. The nutria strongly resemble beavers, but with a highly-arched back and a long, thin, round, sparsely-haired tail, rather than wide and flattened like the beaver. Adults typically reach a body length of 2 ft., weigh 15-20 lbs., and have tails 1-1.5 ft. long. Nutria tracks can reach up to 6 inches long, have 5 toes per foot, and have webbing on the hindfeet, which is often visible in tracks. An adult nutria is about one-third the size of an adult beaver, and over 5 times the size of a muskrat, which has a thin, laterally-flattened (side to side) tail.
