A kind of otter
About
The sea otter is a heavy marine mammal in the weasel family that can stretch over four feet long.
Sea otters are the heaviest species in the weasel family, yet they are among the smallest of all marine mammals. Adults usually range from 30 to 100 pounds (14 to 45 kg), with males growing substantially larger and heavier than females. Unlike seals that rely on thick layers of blubber, sea otters keep their bodies warm solely with the densest fur in the animal kingdom.
From Wikipedia
