Nutria

Nutria (also known as Coypu) is a large, herbivorous, semiaquatic rodent. Originally native to South America, it has since been introduced to North America, Europe, Asia, and Africa, primarily by fur ranchers.

Description

Nutria are about 1 meter (3.3 ft) in total length, half of which is the tail, and they weigh between 5 and 9 kg (11 and 20 lb). They have a coarse, darkish brown outer fur with a soft underfur. They have webbed hind feet and small, dexterous front feet. Nutria have large, bright orange-yellow incisors that can be seen when their mouths are closed.

Habitat and Behavior

Nutria are found near bodies of water, such as rivers, lakes, ponds, and marshes. They are capable of constructing their own burrows, but will also inhabit abandoned burrows of other animals. Nutria are most active during the night, when they feed on a variety of plant materials and occasionally small invertebrates and birds.

Impact on Ecosystems

The introduction of nutria into non-native habitats has had significant ecological impacts. In some areas, their feeding and burrowing behaviors have led to serious erosion and damage to wetland ecosystems. They are considered a pest species in many of the regions where they have been introduced.

Nutria in Cuisine

In some cultures, nutria are also used as a food source. The meat is lean and high in protein, and is often compared to rabbit or dark chicken meat. However, it is not widely consumed due to its association with rodents.
