Elasmobranchii
板鰓亞綱 (鯊魚與魟魚) (sharks and rays) >
Squaliformes (Sleeper and dogfish sharks) >
Oxynotidae (Rough sharks)
Etymology: Oxynotus: oxys (Gr.), sharp; notos (Gr.), back, referring to its keeled back (“dorso carenato”). (See ETYFish); centrina: From “Centrina,” name for this shark dating to at least Giovio’s De romanis piscibus (1524), presumably derived from centrum (L.), prickle or sharp point, referring to spines on both dorsal fins. (See ETYFish).

生態學
海洋 深海底的; 深度上下限 60 - 1309 m (Ref. 128029). 深水域; 70°N - 17°S, 25°W - 36°E (Ref. 54693)
Eastern Atlantic: Bay of Biscay and Mediterranean Sea to Senegal, north to Cornwall, England (apparently as a stray). Compagno et al. (Ref. 5578) reports this species as ranging south to Cape Point, South Africa but Springer 1990 (Ref. 10718) notes Bass et al. 1976 as considering specimens from Walvis Bay distinct from Oxynotus centrina calling attention to the considerably greater distance between dorsal fins in Mediterranean specimens than in specimens taken south of the equator.
東大西洋: 比斯開灣與地中海到塞內加爾, 北至康瓦爾郡，英格蘭。 (顯然地如迷途的魚) Compagno 等人。 (參考文獻 5578) 報告這種分佈南至南非的尖岬但是 Springer 1990 世 (參考文獻 10718) 附註 bass 等人。 1976 當從各方面來看來自沃爾維斯灣的標本不同於，認為注意到非常地較大的 Oxynotus centrina 在地中海的標本背鰭之間的距離超過在佔據赤道南邊的標本中。
Length at first maturity / 大小 / 重量 / 年齡
Maturity: Lm ?, range 50 - ? cm
Max length : 150 cm TL 雄魚/尚未辨別雌雄; (Ref. 247); common length : 55.0 cm TL 雄魚/尚未辨別雌雄; (Ref. 26999)
背棘 (總數): 2; 背的軟條 (總數): 0; 臀棘 0; 臀鰭軟條: 0. A small bizarre-looking shark with an unmistakable high body and bristly textured skin (Ref. 5578). Uniformly grey to grey-brown (Ref. 5578).
一種小的外表奇異的鯊魚有一個明顯的高身體與有鬃毛織紋的皮膚.(參考文獻 5578) 全灰色到灰褐色.(參考文獻 5578)
Found on the outer continental shelf and upper slope (Ref. 5578). Depth range from 60-660 m (Ref. 247) and from 549-777 m in the eastern Ionian Sea (Ref. 56504), and 818-1309 m NW Africa (Ref. 128029). Feeds on polychaetes (Ref. 247) and sipunculids (apparenly a suction feeder which mainly feeds on worm-like prey), which are rapidly digested, and the rapid gastric evacuation could partially explain the vacuity of several guts; teleosts, crustaceans and echinoderms are considered as accessory prey items, thus recorded predation on egg cases of the smallspotted catshark Scyliorhinus canicula remains an occasional phenomenon (Ref. 81816). Ovoviviparous (Ref. 205). Utilized for fishmeal, oil, and smoked and dried salted for human consumption (Ref. 247).
