Otters are aquatic or marine carnivorous mammals, members of the large and diverse family Mustelidae, which also includes weasels, polecats, badgers and others. There are 13 species of otter in 7 genera, with a distribution that is almost worldwide.

Otters have a dense layer (1,000 hairs/mm², 650,000 hairs per sq. in) of very soft underfur which, protected by their outer layer of long guard hairs, keeps them dry under water and traps a layer of air to keep them warm. Unlike most marine mammals (seals, for example, or whales), otters do not have a layer of insulating blubber, and even the marine sea otter must come ashore regularly to wash its coat in fresh water.
