Etymology: Cetorhinus: cetus (L.), from ketos (Gr.) whale, referring to its size; rhinus, an ancient name for sharks, from rhine (Gr.), rasp, alluding to a shark’s jagged, rasp-like skin (See ETYFish); maximus: Latin for greatest, being the largest known fish (i.e., non-mammalian aquatic vertebrate) at the time (superseded by Rhincodon typus) (See ETYFish).

簡短描述 檢索表 | 型態特徵 | 形態測量圖
背棘 (總數) : 0; 臀棘: 0. Distinguished from all other sharks by the enormous gill slits practically encircling the head; dermal denticle gill rakers; pointed snout; huge, sub terminal mouth with minute hooked teeth; caudal peduncle with strong lateral keels, and lunate caudal fin. Body covered with placoid scales. Blackish to grey-brown, grey, or blue-grey, often with irregular white blotches under the head and abdomen (Ref. 43278). Also Ref. 309, 5983.
Body shape (shape guide): elongated; Cross section: circular.

The second largest shark, reportedly reaching 1,220-1,520 cm TL (Ref. 247). Thought to live up to 50 years (Ref. 9030, 89083). Semi-oceanic or oceanic species, highly migratory (Ref. 43278). Found on continental and insular shelves, offshore and often close to land, just off the surf zone; enters enclosed bays (Ref. 247). Coastal-pelagic at 1 meter to unknown depths, probably epipelagic (Ref. 58302). Occurs singly, in pairs or groups of 3 or more, or in huge schools (group of up to 100 individuals has been reported) (Ref. 6871, 43278). Prefers water temperature between 8-16 °C (Ref. 88171). Makes extensive horizontal and vertical movements along the continental shelf and shelf edge to utilize productive feeding areas (Ref. 50200). During the summer months, it is found near the surface of boreal to warm-temperate areas (Ref. 43278) feeding on zooplankton by filtering (Ref. 88781). Found in deeper waters during winter (Ref. 6871, 50200, 58302). Undertakes long transoceanic migrations (e.g. from the British Isles to Newfoundland, Canada (Ref. 88824)) and moves between the northern and southern hemisphere in tropical mesopelagic water (Ref. 88825). These migrations have been found to cover distances of over 9,000 km. May form segregations by size or sex (Ref. 88171). Ovoviviparous (Ref. 50449). Regarded as ordinarily harmless and inoffensive but potentially dangerous if attacked (particularly when harpooned) (Ref. 247). In Bay of Fundy, Canada parasitic lampreys have been found attached to the back of basking sharks and sucking their blood (Ref. 83375). Utilized fresh, frozen and dried, or salted (Ref. 9987). Also valued for its liver for oil, fins for soup, hide for leather and carcass for fishmeal (Ref. 247). May be a potential source of anti-carcinoma drugs (Ref. 6034, 6035). Used in Chinese medicine (Ref. 12166). Threatened due to bycatch fisheries (Ref. 83294).

Distinct pairing with embrace (Ref. 205). Courtship behaviour patterns associated with elasmobranch reproduction were documented from an aerial observation which include 'parallel swimming', 'pectoral biting', 'nudging', and 'male on top of female'. Other mating behaviours particular to this species from the same aerial observation include nose-to-tail following; flank approach; close approach involving rostral contact or proximity with the gill, pectoral fin, vent, and dorsum; and echelon swimming (Ref. 37026). Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). Estimated gestation period 12-36 months (Ref. 247, 1765, 9030, 88829); TL at birth estimated between 150-200 cm; mating thought to take place during early summer; a female giving birth to young captured in August in Norwegian waters (Ref. 5983). Over a study period of 5 years, courtship-like behaviour was observed off southwest England between May and July, always in surface waters along thermal fronts; because actual mating was not observed, this may occur in deeper water (Ref. 88831). A one-year resting period between pregnancies is thought to occur, resulting in a 2-4 year interval between litters (Ref. 9030, 1765, 88829). Only one pregnant female has been observed giving birth to a litter of 6 pups (Ref. 88830).四海為家的人。 西大西洋: 加拿大紐芬蘭到美國的佛羅里達; 巴西南部到阿根廷。 東大西洋: 冰島，挪威與 Barents海西部到地中海與塞內加爾; 也南非的開普省西部。 西太平洋: 日本到紐西蘭。 東太平洋: 阿拉斯加灣到智利; 可能地加拉巴哥群島。 高度遷移的種,1982年海事法會議的附件一.(參考文獻 26139) 過度漁撈導致瀕臨滅絕由於生育力極低.(參考文獻 36717) 國際間的買賣限制。 ( 引用 附錄 2, 自從 28.5.2003 以後)
