Morphometric investigations of the gill apparatus in the pelagic Baikal sculpins (Cottocomephorinae) reveal a relatively large gill respiratory area (GRSA). Allometric relationship between GRSA and body weight is expressed by the equation: Y = 746.61W 0.918 for C. inermis and that Y = 655.68W 0.913 for C. grewingki . In calculations per body weight unit the GRSA values C. inermis are a little higher than those in C. grewingki . Obtained numerical data seem to be in accordance with difference in biological activity of species examined. Their GRSA is several times larger than that in previously examined the bathypelagic Comephorus dybowskii and deep bottom dweller Cottinella boulengeri .
