This article is about the animal. For other uses, see Otter (disambiguation). Otters are carnivorous mammals in the subfamily Lutrinae. The 13 extant otter species are all semiaquatic, aquatic or marine, with diets based on fish and invertebrates. Lutrinae is a branch of the weasel family Mustelidae, which also includes badgers, honey badgers, martens, minks, polecats, and wolverines.
Mongooses bear a striking resemblance to mustelids, having long faces and bodies, small, rounded ears, short legs, and long, tapering tails. Most are brindled or grizzly; a few have strongly marked coats. Their nonretractile claws are used primarily for digging.Mongooses, much like goats, have narrow, ovular pupils. Most species have a large anal scent gland, used for territorial marking and signaling reproductive status. The dental formula of mongooses is similar to that of viverrids: 3.1.3-4.1-23.1.3-4.1-2.ongooses range in weight from the common dwarf mongoose, at 320 g (11 oz), to the cat-sized white-tailed mongoose, at 5 kg (11 lb).
