Lumpsuckers or lumpfish are mostly small scorpaeniform marine fish of the family Cyclopteridae. They are found in the cold waters of the Arctic, North Atlantic, and North Pacific oceans. The greatest number of species are found in the North Pacific. The roe of ''Cyclopterus lumpus'' (''the'' lumpsucker or lumpfish to most Europeans and people living along the East Coast of the United States), known as ''stenbider'' (literally "stone biter") in Danish, is used extensively in Scandinavian cuisine. The roe is also used as an affordable alternative to the caviar produced by sturgeons. The family name ''Cyclopteridae'' derives from the Greek words ''κύκλος'' (kyklos), meaning "circle", and ''πτέρυξ'' (pteryx), meaning "wing" or "fin", in reference to the circle-shaped pectoral fins of most of the fish that comprise this family. == Description == Lumpsuckers are named appropriately enough; their portly bodies are nearly spherical with generally drab coloration and lithic patterns. The "sucker" part refers to the fish's modified pelvic fins, which have evolved into adhesive discs (located ventrally, behind the pectoral fins); the fish use these discs to adhere to the substrate. Many species have bony, wart-like ''tubercles'' adorning the head and body; these are important taxonomic features of the family. The simple, rounded fins are small with the exception of the broad, fan-like pectorals, which actually extend ventrally. The first of the two dorsal fins is spinous, with 4-8 spines; in some species, this fin is completely overgrown with skin and therefore not visible. While the lateral line in lumpsuckers is otherwise reduced or absent, it is well developed in the head; some species even have tubular, whisker-like external projections of the opercular canal, which is a part of the cranial lateral line system. The relatively small mouths of lumpsuckers are lined with narrow rows of small conical teeth. The gas bladder is absent. In terms of length, lumpsuckers range in size from two centimetres in the case of ''Lethotremus awae'' up to 50 centimetres in the case of the common lumpsucker ''Cyclopterus lumpus''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lumpsucker」の詳細全文を読む スポンサード リンク
