Comephorus
''Comephorus'', known as the golomyankas or Baikal oilfish, are a genus comprising two species of peculiar, sculpin-like fishes endemic to Lake Baikal in Russia. ''Comephorus'' is the only genus in the family Comephoridae. Golomyankas are pelagic fishes which make the main food source of the Baikal seal. ==Description== ''Comephorus'' have translucent bodies with no scales. They have long pectoral fins, and although pelvic bones are present, they lack pelvic fins. They have a strong lateral line. The lateral line system on the head consists of large cavities linked by narrow, bony bridges with small external pores. Lack of a swim bladder, high lipid content and porous bones allow the fish to tolerate varying pressure extremes as they move through the water column. Over a third of their body weight (38.9%) is oil. The common name ''golomyanka'' literally means 'naked''.
