板鰓亜鋼(サメとエイ類) (sharks and rays) >
Lamniformes (Mackerel sharks) >
Odontaspididae (Sand tiger sharks)
Etymology: Odontaspis: Etymology not explained, presumably odontos (Gr.), tooth, and aspis (Gr.), shield, perhaps referring to how teeth comprise a prominent narrow cusp provided with two or more small “side teeth” (translation), i.e., cusplets, which, with some imagination, could be said to “shield” the main cusp; another explanation: aspis (L.), viper, perhaps referring to outwardly pointing teeth of O. ferox, like that of a viper. (See ETYFish); ferox: Latin for fierce, possibly referring to what Risso described as its “La voracité extrême” and/or its toothy and ferocious countenance. (See ETYFish).

生態学
海 底生の漂泳性; 深さの範囲 10 - 2000 m (Ref. 26346), usually 13 - 880 m (Ref. 89422). Deep-water; 50°N - 49°S, 180°W - 180°E (Ref. 54681)
Eastern Atlantic: Gulf of Gascony, Madeira, Morocco, Mediterranean; also Cape Verde (Ref. 27000). Western Atlantic: Yucatan Shelf, Mexico (Ref. 9939), Brazil (Ref. 53443). Indo-West Pacific: off South Africa and Maldives, Madagascar, southern Japan, Australia, and New Zealand (Ref. 13568). Expected to occur in the Western Central Pacific (Ref. 13568). Central Pacific: off Hawaii (Ref. 13568). Eastern Pacific: off southern California, USA and Baja California, Mexico (Ref. 13568).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ? range ? - 360 cm
Max length : 450 cm TL オス/雌雄の選別がない; (Ref. 89422); 最大公表体重: 289.0 kg (Ref. 9939)
背面の脊椎 (合計) : 0; 肛門の骨: 0. A shark with a short, pointed snout, small eyes, protruding spike-like teeth, and small, equal-sized dorsal and anal fins; first dorsal closer to pectoral than to pelvic fins (Ref. 5578). Grey above, paler below (Ref. 6586); may have red spots on sides (Ref. 5578).
Found on or near the bottom of the continental and insular shelves and upper slopes (Ref. 6871); sometimes in shallow water (Ref. 6871). Tagging showed the species dives up to 2,000 m at Malpelo Island, Colombia (S.Bessudo, pers.comm. 06/09). Feeds on small bony fishes, squids, and crustaceans (Ref. 13568). Uses its long body cavity and large, oily liver to regulate buoyancy. Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 50449). Not implicated in attacks on people (Ref. 247). Flesh utilized for human consumption and liver for its high squalene content (Ref. 247); utilization of fins, jaws and cartilage (Ref.58048).
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 幼生
Exhibit ovoviparity (aplacental viviparity), with embryos feeding on other ova produced by the mother (oophagy) after the yolk sac is absorbed (Ref. 50449). Two young born at 105 cm or larger (Ref. 26346). Distinct pairing with embrace (Ref. 205).
