mongoose Facts. Although they appear remarkably similar to weasels in form and lifestyle, mongooses are actually members of the superfamily feliforma, or cat-like carnivores, while weasels are in the superfamily caniforma or dog-like carnivores.
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).
