The silver otter (Lutra Argentine) is believed to be an extinct otter of the Lutra genus of otters. Its silver-hued coat is similar to others in the Lutra genus.

Lutra otters are mammals that live partially on land and partially on water. They are found near shallow streams and slow-moving rivers. Their diet consists primarily of fish, small rodents, or water bugs. Lutra hunt primarily at night and stay in their dens during the daytime.

The silver otter is thought to be very similar to the European otter, also in the Lutra genus. Males are estimated to be between 90 to 145 cm in length, including the tail. The females in this genus are shorter than the males by about 25%.
