Description

The longfin Baikal sculpin is a slender, semi-pelagic sculpin of the family Cottocomephoridae reaching about 22 cm and endemic to Lake Baikal. Unlike most sculpins, which live on the bottom, this species swims freely in the open, deep water, for which it has large pectoral and dorsal fins and a slender body. In schools it feeds on zooplankton, mainly amphipods, and on fish larvae. To spawn it moves to shallow, rocky shores, where the male guards the clutch laid on stones. The species forms an important link in Baikal's food web and is a main prey of the Baikal seal (nerpa) and of commercial fish; locally it is also eaten by people.
