Una nutria de río adulta puede pesar entre 5,0 y 14 kg (11.0 y 30.9 lb). La nutria de río está protegida y aislada por una capa de pelaje gruesa y repelente al agua.
La nutria de río, miembro de la subfamilia Lutrinae, es tan versátil en el agua como en la tierra. Establece una madriguera cerca de la orilla del agua en el río, lago, pantano, litoral costero, plano de marea, o ecosistemas estuarinos. La guarida típicamente tiene muchas aberturas de túnel, uno de los cuales por lo general permite a la nutria para entrar y salir del cuerpo de agua. Las nutrias femeninas dan a luz en estas madrigueras subterráneas, produciendo camadas de uno a seis.
Las nutrias de río de América del Norte, como la mayoría de los depredadores, acechan a las especies más fácilmente accesibles. El pescado es un alimento muy apreciado entre las nutrias, pero también consumen diversos anfibios (como ranas), tortugas y cangrejos. Las instancias de nutrias de río comiendo pequeños mamíferos y ocasionalmente aves han sido reportadas también.
