A common but habitat-limited tropical shark found close inshore to well as offshore near or on insular or continental shelves (Ref. 244). Prefers clear water with coral and rocky bottoms (Ref. 244). Although a coastal pelagic species, it is capable of crossing considerable distances of open ocean between islands (at least 50 km) (Ref. 244). Juveniles restricted to shallower water, in 25 m or less (Ref. 244; 37816). Found in superficial aggregations (Ref. 244). Tends to feed near the bottom but may take bait from the surface (Ref. 5485). Feeds mainly on bottom fishes, also squid and octopi (Ref. 244). In the Galapagos Is. it preys on sea lions and marine iguanas (Ref. 28023). Inquisitive and sometimes aggressive, displaying a 'hunch' position ( arched back, raised head and lowered caudal and pectoral fins, while twisting and rolling) near divers that may be followed by biting (Ref. 58085). Viviparous (Ref. 50449). 6 to 16 young of 57 to 80 cm are born per litter (Ref. 1602).
一种常见的但是当外海邻近岛屿棚或大陆架或在上面的时候，栖息地受限的热带鲨鱼发现近岸涌出.(参考文献 244) 偏爱底部为珊瑚与岩石的清澈水域。 (参考文献 244) 虽然一个海岸的大洋性鱼种, 它能够在岛 (至少 50 公里) 之间的开放性海域的横渡相当长的距离.(参考文献 244) 稚鱼局限于较浅的水域了, 在 25 公尺以内中 (参考文献 244; 37816)。 发现于表面的群集了。 (参考文献 244) 倾向在底部附近的吃但是可能采取来自表面的诱饵.(参考文献 5485) 主要吃底层鱼类，也捕食乌贼与章鱼。 (参考文献 244) 在加拉巴哥岛，它捕食海狮与海洋的鬣蜥蜴。 (参考文献 28023) 侵略性与对人类有危险性.(参考文献 9997) 胎生的.(参考文献 50449) 生产6 到 16只, 57 到 80 公分的幼鱼每胎。 (参考文献 1602)
