Coypu, also known as nutria, is a semi-aquatic rodent species native to South America. The scientific name for coypu is Myocastor coypus, and it belongs to the family Myocastoridae.
Coypus are large rodents with stocky bodies, short legs, and a long, round, and scaly tail. They typically measure around 17-25 inches (43-63 cm) in length, excluding the tail, which can reach a length of 12-18 inches (30-45 cm). They have webbed hind feet, enabling them to swim adeptly in aquatic environments. They possess reddish-brown fur, with their underparts being lighter in color. Coypus have large orange incisor teeth that continuously grow throughout their lives.
Coypus are known for their adaptability to various habitats, including freshwater and brackish marshes, swamps, lakes, and rivers. They are herbivorous animals, feeding on a variety of aquatic vegetation like cattails, water lilies, and grasses. Coypus are adept swimmers and are capable of staying submerged for extended periods, aided by their partially webbed feet and valve-like nose and ears that can be closed to prevent water entry.
Due to their destructive feeding habits and ability to burrow, coypus have been introduced and have become invasive in many countries outside their native range. They cause significant damage by destroying crops, digging dens that can weaken riverbanks, and altering wetland habitats. Managing coypu populations has become necessary in these areas to mitigate their impact on ecosystems and agricultural activities.
