The pimelodid, also known as the naked catfish or long whiskered catfish family includes approximately 300 known species. Like many catfish, their bodies lack scales.
Different species vary in size considerably, with the larger ones reaching up to 3m. Pimelodid are active at night and feed alone, generally spending all their time at the bottom of the water. Barbels or whiskers around the mouth are covered with taste buds which help them find food, compensating for poor eyesight. Larger members of this group feed on fish and other animals, including monkeys that fall into the water.
