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). Aggressive and dangerous to people (Ref. 9997). Viviparous (Ref. 50449). 6 to 16 young of 57 to 80 cm are born per litter (Ref. 1602).
