背面の脊椎 (合計): 0; 背鰭 (合計): 0; 肛門の骨 0; 臀鰭: 0. A large thresher with very large eyes, an indented forehead, a broad caudal tip, and curved broad-tipped pectoral fins; 1st dorsal fin further back than in other threshers (Ref. 5578). Upper lobe of caudal fin very long and strap-like almost or quite equal to length of rest of shark; lower lobe short but well developed (Ref. 13570).

生物学     用語集 (例 epibenthic)

Occurs in coastal waters over continental shelves, sometimes close inshore in shallow waters, and on the high seas far from land (Ref. 247, 43278, 58302). Oceanic, pelagic and near bottom at 1->500 m (Ref. 58302). Depth range to at least 500 m (Ref. 247). Feeds on pelagic fishes (lancetfishes, herring, mackerel and small billfishes (Ref. 43278)) and bottom fishes (hake (Ref. 43278)) and squids (Ref. 247). Ovoviviparous, embryos feeding on yolk sac and other ova produced by the mother (Ref. 43278, 50449). Stuns its prey with its long caudal fin (Ref. 247). Utilized for human consumption, liver oil for vitamins, skin for leather, and fins for shark-fin soup (Ref. 247). Marketed fresh and may be broiled, baked or grilled, but unsuitable for steaming, boiling or frying; meat may be salted and dried (Ref. 9987). Also Ref. 33743.

Life cycle and mating behavior 成熟 | 繁殖 | 放精 | | 生産力 | 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). With 2-4 young per litter (usually 2) (Ref. 247). Size at birth between 64-106 cm (Ref. 247); 100-140 cm TL (Ref.58048). No fixed mating or birthing season. Distinct pairing with embrace (Ref. 205).
