生物学特性     字汇 (例如 epibenthic)

Found on continental and insular shelves, mainly over sandy, shell, and coral bottoms. Feeds on small fishes, including pinfish (Sparidae) and porcupine fish. Preyed on by larger sharks. Viviparous (with a yolk-sac placenta), with 3 to 6 young per litter. Performs a 'hunch' display, with back arched, caudal lowered and head raised, as a possible threat display when confronted by divers. Utilized dried salted for human consumption. Minimum depth from Ref. 055176.

栖息于大陆架与岛屿棚了, 主要地沙的之上, 贝壳 , 与珊瑚底部。 吃小鱼,包括 pinfish(Sparidae) 与二齿 鱼。 被较大的鲨鱼捕食了。 胎生的 (具有一个卵黄囊胎盘), 对 6个幼鱼有三个每胎。 执行一个 '肉峰' 显现, 藉由背面弓形的, 尾部的低与升起的头部, 作为一个可能的威胁显现当面对在潜水者手边。 乾燥盐腌利用供人类消费。
