The cusk-eel family (Ophidiidae) is a group of marine bony fishes in the order Ophidiiformes. The scientific name is from the Greek ''ophis'' meaning "snake", and refers to their eel-like appearance. However, they can be distinguished from true eels of the order Anguilliformes by their ventral fins, which are developed into a forked barbel-like organ below the mouth in the cusk-eels; in the true eels by contrast they are never well-developed and usually missing entirely. They are found in temperate and tropical oceans throughout the world. They live close to the sea bottom, ranging from shallow water to depths below . One species, ''Abyssobrotula galatheae'', was recorded at the bottom of the Puerto Rico trench, making it the deepest recorded fish at . The largest species, ''Lamprogrammus shcherbachevi'', grows up to in length, but most species are shorter than 1 m. Unlike their close relatives, the viviparous brotulas of the Bythitidae, they are egg-laying, and the larvae live amongst the plankton, relatively close to the surface.〔 A few species are fished commercially, most notably the pink cusk-eel, ''Genypterus blacodes''. ==Genera== The cusk-eel family contains about 240 species, grouped into 50 genera: Subfamily Brotulinae * Genus ''Brotula'' – typical brotulas Subfamily Brotulotaenilinae * Genus ''Brotulotaenia'' Subfamily Neobythitinae * Genus ''Abyssobrotula'' * Genus ''Acanthonus'' * Genus ''Alcockia'' * Genus ''Apagesoma'' * Genus ''Barathrites'' * Genus ''Barathrodemus'' * Genus ''Bassogigas'' * Genus ''Bassozetus'' * Genus ''Bathyonus'' * Genus ''Benthocometes'' * Genus ''Dannevigia'' – Australian tusk * Genus ''Dicrolene'' * Genus ''Enchelybrotula'' * Genus ''Epetriodus'' – needletooth cusk * Genus ''Eretmichthys'' * Genus ''Glyptophidium'' * Genus ''Holcomycteronus'' * Genus ''Homostolus'' – filament cusk * Genus ''Hoplobrotula'' * Genus ''Hypopleuron'' – whiptail cusk * Genus ''Lamprogrammus'' * Genus ''Leptobrotula'' * Genus ''Leucicorus'' * Genus ''Luciobrotula'' * Genus ''Mastigopterus'' * Genus ''Monomitopus'' * Genus ''Neobythites'' * Genus ''Neobythitoides'' * Genus ''Penopus'' * Genus ''Petrotyx'' * Genus ''Porogadus'' * Genus ''Pycnocraspedum'' * Genus ''Selachophidium'' – Gunther's cusk-eel * Genus ''Sirembo'' * Genus ''Spectrunculus'' * Genus ''Spottobrotula'' * Genus ''Tauredophidium'' * Genus ''Typhlonus'' * Genus ''Ventichthys'' – East-Pacific ventbrotula * Genus ''Xyelacyba'' Subfamily Ophidiinae * Genus ''Cherublemma'' – black brotula * Genus ''Chilara'' – spotted cusk-eel * Genus ''Genypterus'' * Genus ''Lepophidium'' * Genus ''Menziesichthys'' * Genus ''Ophidion'' * Genus ''Otophidium'' * Genus ''Parophidion'' * Genus ''Raneya'' – banded cusk-eel 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「Cusk-eels」の詳細全文を読む スポンサード リンク
