Quick Answer
Nutria can be differentiated from other rodents by their large, orange incisors, webbed hind feet, and stocky, semi-aquatic body shape. They often have a distinctive, musky odor. A close examination of their physical characteristics is necessary to confirm identification.
Physical Characteristics
Nutria are large rodents, typically measuring 17-25 inches in length and weighing 8-20 pounds. They have coarse, brown fur and a distinctive, orange-colored incisor that protrudes from their lower jaw. These incisors are used for gnawing and cutting, and are a key identifier of the species.
Habitat and Behavior
Nutria are semi-aquatic and are often found in areas with slow-moving water, such as marshes, swamps, and bayous. They are herbivores and feed on aquatic plants, grasses, and other vegetation. They are skilled swimmers and can stay underwater for up to 5 minutes, using their webbed hind feet to propel themselves through the water.
Identification Techniques
To accurately identify nutria, it is essential to examine their physical characteristics, including their incisors, fur, and body shape. A close inspection of their tracks can also help confirm identification, as nutria have large, paddle-like tracks with a distinctive “V” shape. Additionally, nutria often have a distinctive musky odor, which can be detected by approaching the animal cautiously and sniffing for the scent.
