It has a stout body set on short legs. It is easily distinguished by the black stripe that runs laterally on both sides of its neck. The body coloration is a rusty brown to grizzled grey. The relatively short tail is mostly black, with grey at the base. The stripe-necked mongoose feeds on frogs, crabs, mouse deer, hares, rodents, fowl, and reptiles. This mongoose species is more diurnal in habits. They prefer forested areas near a fresh water source. They are often found in swamps and rice fields.
