Additionally, their barb-like design makes them extremely difficult to remove, which could prove beneficial for securing medical implants. [75] Increased local awareness of viral, bacterial and parasitic transmission from nutria to humans and livestock will be of greater importance as climate change progresses. As a result, populations of nutrias often contract and even become locally or regionally extinct as in the Scandinavian countries and such US states as Idaho, Montana, and Nebraska during the 1980s. A semi-aquatic South American rodent, Hydrochoerus hydrochaeris, the largest living rodent. A nutria is often mistaken for a muskrat (Ondatra zibethicus), another widely dispersed, semiaquatic rodent that occupies the same wetland habitats. Described as a river rat or giant swamp rat, the rodent known in North America as the nutria originally came from South America, where it is called the coypu.
