The crab-eating mongoose (Herpestes urva) is a mongoose species ranging from the northeastern Indian subcontinent and Southeast Asia to southern China and Taiwan. It is listed as Least Concern on the IUCN Red List. Throughout its wide range there are many languages and therefore various common names for the species. In particular, according to at least some major dictionaries, the source of the species name urva (which at one time was also the name of the genus, as in: Urva urva) was the Nepali language urvá or arvá.
The crab-eating mongoose is grey, with a broad white stripe on its neck extending from its cheeks to its chest. Its throat is steel-gray with white ends of its hair, rendering a salt and pepper appearance. Its hind feet possess hairy soles. Its tail is short and homogeneously colored with a fairer tip. The body of the crab-eating mongoose is 36–52 cm (14–20 in) in length, and 1–2.3 kg (2.2–5.1 lb) in weight.
Distribution and habitat
The crab-eating mongoose is common in Vietnam, Laos, Cambodia, Thailand, Peninsular Malaysia, northern Myanmar and northeastern India. The species is rare in Bangladesh. It has been recorded at elevations from sea level to 1,800 m (5,900 ft). In Nepal, it inhabits subtropical evergreen and moist deciduous forests, and has also been observed on agricultural land near human settlements.
Ecology and behaviour
Crab-eating mongooses are usually active in the mornings and evenings, and were observed in groups of up to four individuals. They are supposed to be good swimmers, and hunt along the banks of streams and close to water.
Despite their common name, their diet consists not only of crabs, but also just about anything else they can catch, including fish, snails, frogs, rodents, birds, reptiles, and insects.
