生物學特性     字彙 (例如 epibenthic)

An inshore and offshore shark found over or adjacent to continental and insular shelves and offshore banks (Ref. 244). Prefers offshore islands, coral reefs and banks (Ref. 244). Benthopelagic (Ref. 58302). Feeds mainly on benthic and midwater fishes (including scombrids), also rays, cephalopods (Ref. 244, 1602), and small sharks and crustaceans (Ref. 89972). Viviparous (Ref. 50449). Up to 11 young, size 50 to 60 cm, are born after a gestation period of 12 months (Ref. 1602, 37816). Potentially dangerous (Ref. 9997). Presumably taken by fisheries in areas where it occurs (Ref. 9997). Caught irregularly by shark and tuna longline and tuna gillnet fisheries. Utilized for its fins (high value in adults), meat, skin and cartilage (Ref.58048). Probably utilized fresh and dried-salted for human consumption (Ref. 9997).

一種近岸的與外海鯊魚發現在或者上面.鄰近大陸棚與島嶼棚與近海淺堆。 (參考文獻 244) 偏愛離岸島嶼,珊瑚礁與淺堆。 (參考文獻 244) Engybenthic 與大洋底棲性魚種.(參考文獻 58302) 主要吃底棲性與中層水域魚, 也鰭條,頭足類動物 (參考文獻 244,1602) 與小的鯊魚與偶然地頭足類動物.(參考文獻 37816) 胎生的.(參考文獻 50449) 高達 11個幼魚, 大小 50 到 60 公分, 出生在妊娠之後 12個月的時期.(參考文獻 1602,37816) 可能危險.(參考文獻 9997) 推測為在區域中被漁民捕獲在那裡它出現.(參考文獻 9997) 可能生鮮利用與乾燥鹽醃供人類消費.(參考文獻 9997)
