Nutria vs. Capybara: What's the Difference?
Nutria are semi-aquatic rodents native to South America but found in various parts of the world, while Capybaras are the largest rodents globally, also native to South America.
Nutria and Capybara both hail from South America and are semi-aquatic rodents. However, they belong to different families within the rodent order. Nutrias are smaller and belong to the family Myocastoridae, while Capybaras are part of the Caviidae family.
In terms of size, the Nutria typically measures about 1 foot in body length, with a tail of a similar length. On the other hand, the Capybara is much larger, often reaching up to 4.5 feet in length and weighing as much as 145 pounds.
Another distinguishing characteristic is their teeth. Nutrias possess sharp, orange-tinted incisors, while Capybaras have squared-off snouts with less pronounced teeth that aren't distinctly colored.
Behaviorally, Nutrias are often more aggressive than the relatively docile Capybara. While both animals live in social groups, Capybaras are known for their peaceful nature and often coexist harmoniously with other animals.
Lastly, while both Nutria and Capybara have been sought for their fur and meat, the introduction of Nutria to non-native areas has led to them being seen as invasive pests, damaging water systems and competing with native species. Capybaras, in contrast, haven’t been as widespread and remain largely in their native habitats.
