生物学特性     字汇 (例如 epibenthic)

Inhabits coastal waters (Ref. 7251). Generally found near shore, to depths of 10 m. Both adults and juveniles frequent estuaries and surf zones (Ref. 27549). Bottom feeder with fish, clams, worms and shrimps. It causes a number of injuries to bathers and waders (Ref. 26938). Ovoviviparous (Ref. 50449). Litters of 2-4 pups; gestation 10-11 months, including a period of embryonic diapause (Ref. 114953).

栖息于沿岸水域。 (参考文献 7251) 通常发现近岸, 到深度 10 公尺。 于底部捕食鱼，蛤，蠕虫与虾。 它引起对游泳者与步涉者的一些伤害。 (参考文献 26938) 卵胎生的.(参考文献 50449)

Life cycle and mating behavior 成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼

Exhibit ovoviparity (aplacental viviparity), with embryos feeding initially on yolk, then receiving additional nourishment from the mother by indirect absorption of uterine fluid enriched with mucus, fat or protein through specialised structures (Ref. 50449). Distinct pairing with embrace (Ref. 205).西大西洋: 紐澤西州 (極少在麻薩諸塞州) ，美國與墨西哥灣北部到阿根廷; 在西印度群島廣泛分佈。 在安地列斯群島各處.(參考文獻 26938)
