Nutria Overview
Appearance
The nutria, also known as the coypu, is a medium-sized rodent with a sleek, cylindrical body. It has dense, coarse fur that ranges in color from dark brown to reddish-brown, often appearing wet due to a gland that secretes oil. Nutrias have webbed feet, which make them strong swimmers, and their tails are long, scaly, and nearly hairless.
They possess large, orange-colored incisors that continuously grow throughout their lives, similar to other rodents. Nutrias exhibit sexual dimorphism, with males typically being larger than females
Origins And Evolution
The nutria, or coypu, is a semi-aquatic rodent with an evolutionary history that traces back to South America. It belongs to the family Myocastoridae, a group of rodents that originated on the continent. The nutria’s ancestors evolved in the marshy regions of South America, developing adaptations for a semi-aquatic lifestyle.
Over time, they expanded their range to other parts of South America, North America, Europe, Asia, and Africa. Nutrias were introduced to various regions by humans for fur farming, which led to their establishment in new ecosystems. This adaptability has allowed the nutria to thrive in diverse habitats, making it a successful invasive species in some areas.
Behavior and Lifestyle
Nutrias are primarily herbivorous, semi-aquatic rodents known for their active and social behavior. They are excellent swimmers and spend a significant portion of their lives in and around freshwater habitats such as wetlands, rivers, and ponds.
Nutrias are highly adaptable and can thrive in both natural and human-altered environments. They are typically crepuscular or nocturnal, being most active during dawn and dusk. Nutria colonies often consist of several individuals living together, and they construct burrows near the water’s edge for shelter and protection.

Nutria FAQs
Are nutrias related to beavers?
No, nutrias are not closely related to beavers. They belong to different rodent families and have distinct characteristics.
Are nutrias native to North America?
No, nutrias are not native to North America. They were introduced to the continent for fur farming and have become invasive in some regions.
Do nutrias build dams like beavers?
No, nutrias do not build dams. They construct burrows in the banks of water bodies for shelter and nesting.
Are nutrias good swimmers?
Yes, nutrias are excellent swimmers and are well-adapted to their semi-aquatic habitats.
What is the purpose of a nutria’s large, orange incisors?
Nutrias’ large incisors continuously grow throughout their lives and are used for gnawing on vegetation, including aquatic plants and roots.
