The Bighead sculpin (Batrachocottus baicalensis) is a freshwater fish of the family Cottocomephoridae that grows up to 19 cm.
Description
The bighead sculpin is a stocky freshwater sculpin of the family Cottocomephoridae reaching about 19 cm and endemic to Lake Baikal. Characteristic are the strikingly large, broad head and the broad, fan-shaped pectoral fins with which the fish presses against the bottom; the brown-mottled, scaleless body blends well against stones. The species lives on stone and rock bottoms of shallow to moderate water of Lake Baikal and is one of the numerous sculpins found only in this ancient lake. As an ambush predator it seizes amphipods, insect larvae, fish eggs and small fish. In the breeding season the male guards the eggs laid under a stone. The sculpins form an important link in Baikal's food web.
