Cottocomephoridae
Cottocomephoridae, or the bighead sculpins or Baikal sculpins, are a family of scorpaeniform fishes mostly endemic to Russia where they are mostly found in Lake Baikal and surrounding lakes and rivers.
The Catalog of Fishes does not recognize Cottocomephoridae as a separate family, but includes its members in the Cottidae.
Members of Cottocomephoridae form a major part of the diet of the Baikal seal, especially in the autumn.
