The Stone sculpin (Paracottus knerii) is a freshwater fish of the family Cottocomephoridae that grows up to 14 cm.
Description
The stone sculpin is a stocky freshwater sculpin of the family Cottocomephoridae reaching about 14 cm. Characteristic are the 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 among stones. The species lives on stone and rock bottoms of shallow to moderate water of Lake Baikal and adjacent rivers in Siberia, and is one of the most common bottom fish of the lake. As an ambush predator it seizes insect larvae, small crustaceans such as amphipods and fish eggs. In spring the male guards the eggs laid under a stone until they hatch. Because of its small size it has no fishery importance, but it is an important prey for predatory fish.
