[[ Genus Cottunculus View in CoL View at ENA ZBK ]]

Among the approximately 29 species of fathead sculpins (Psychrolutidae) eight species are considered by Eschmeyer (2007) to belong to the genus Cottunculus Collett ZBK , 1875 (subfamily Cottunculinae), yet from a morphological analysis Nelson (1982, 1989) concludes that one of these, C. gyrinoides Weber ZBK , 1913, belongs to the subfamily Psychrolutinae (possibly genus Ebinania ZBK ). The remaining seven species are all benthic and range in depth from shallow inshore waters to about 2200 m. They are distributed in the Pacific ( C. nudus Nelson ZBK , 1989) and Atlantic oceans ( C. granulosus Karrer ZBK , 1968; C. spinosus Gilchrist ZBK , 1906; C. thomsonii ( Guenther , 1882); C. microps Collett ZBK , 1875; C. sadko Essipov ZBK , 1937; C. konstantinovi Myagkov ZBK , 1991), C. sadko ZBK also in the Beaufort Sea (Nelson & Nakamura 1980, Nelson 1982, 1989, 2003, Fedorov & Nelson 1986, Myagkov 1991, Mecklenburg et al. 2002). While C. nudus ZBK , C. granulosus ZBK and C. spinosus ZBK are found in tropical waters or on the Southern Hemisphere, the other species range from tropical to northern temperate and arctic waters.
