生物學特性     字彙 (例如 epibenthic)

A little-known inshore, coastal pelagic species (Ref. 9997). Feeds mainly on fishes, also takes crustaceans and cephalopods (Ref. 6871). Viviparous (Ref. 50449). Probably taken in fisheries where it occurs (Ref. 9997). Utilized fresh and dried salted for human consumption; fins used in the oriental shark fin trade; liver oil processed for vitamins (Ref. 9997).

所知極少的近海又海岸的大洋性魚種.(參考文獻 9997) 主要吃魚, 也捕食甲殼類動物與頭足類動物.(參考文獻 6871) 胎生的.(參考文獻 50449) 可能採自了漁場在那裡它出現.(參考文獻 9997) 生鮮使用與乾燥鹽醃供人類消費; 鰭被用於東方的鯊魚鰭貿易了; 肝油加工成維他命了。 (參考文獻 9997)
