Nutria

The nutria, or coypu, is a large semiaquatic rodent native to South America. It was introduced elsewhere for fur farming and is invasive in many regions.

Myocastoridae: Myocastoridae is the rodent family containing the living genus Myocastor. Nutria are the sole living species in this family.
Fur farming: Fur farming is the raising of animals in captivity for their pelts. Nutria were transported and bred outside South America for their fur.
Marsh loss: Marsh loss is the reduction or disappearance of vegetated wetland habitat. Intensive nutria grazing can remove plants faster than marshes recover.
South America: South America is a continent extending from the Caribbean coast to Cape Horn. Nutria are native to its temperate and subtropical regions.
Rodent: Rodents are mammals characterized by a pair of continuously growing incisors in each jaw. Their gnawing incisors are a defining feature of nutria.
Invasive species: An invasive species is a nonnative organism that spreads and causes ecological, economic, or social harm. Introduced nutria damage wetlands and agriculture in several regions.
Ecosystem engineering: Ecosystem engineering is the alteration of habitats by organisms through their physical activities. Nutria change wetland structure by consuming vegetation and disturbing soils.
Myocastor coypus: Myocastor coypus is the scientific name of the nutria, also known as the coypu. This is the species name used in zoological classification.
Semiaquatic mammal: A semiaquatic mammal uses both aquatic and terrestrial habitats for feeding, movement, or shelter. Nutria forage and swim in water but also travel and feed on land.
Nutria control: Nutria control comprises methods used to reduce or contain nutria populations. Affected regions use trapping, hunting, and other measures to limit damage.
