Circumglobal in tropical and temperate seas. Western Atlantic: Massachusetts, USA to Uruguay, including Gulf of Mexico and the Caribbean. Eastern Atlantic: Iceland to Angola. Indo-Pacific: Red Sea and East Africa to Hawaii and Tahiti, north to southern Japan, south to New Zealand. Eastern Pacific: southern California, USA to Peru, including the Revillagigedo, Cocos, and Galapagos islands. Highly migratory species, Annex I of the 1982 Convention on the Law of the Sea (Ref. 26139).

Biology     Glossary (e.g. epibenthic)

Usually found near surface to depths of 140 m (Ref. 26938). Occurs on or adjacent to continental and insular shelves, frequenting river estuaries, off wharves and jetties in harbors, and in coral atolls and lagoons (Ref. 244). Bottom-associated, sometimes pelagic (Ref. 58302). Also off oceanic islands far from other islands and continental land masses (Ref. 244). Makes excursions in the open ocean, but is not a truly oceanic species (Ref. 244). Nocturnal feeder on other sharks, rays, bony fishes, marine mammals, tortoises, seabirds, sea snakes, squids, gastropods, crustaceans, detritus (Ref. 9997), also including toxic or armored fish species such as Lactoria cornuta or Diodon hystrix, porpoises, whales, sea turtles, cephalopods, domestic animals and humans (Ref. 37816). It also feeds on carrion and garbage, including cans, pieces of metal and burlap bags (Ref. 26938). Second only to Carcharodon carcharias in recorded attacks on humans with at least 27 documented attacks sourced to it . One specimen, reportedly taken off Indo-China, weighed 3,110 kg and measured 740 cm (Ref. 9987). May be kept in an aquaria, but does not last for more than a few months (Ref. 244). Ovoviviparous (Ref. 50449). Up to 80 young of 51 to 104 cm are born per litter (Ref. 1602). Valued for its meat, fins, hide and liver oil (Ref. 9997) and also for its jaws and cartilage (Ref. 58048). Often used for fishmeal (Ref. 9997). Utilized fresh, dried-salted, smoked and frozen (Ref. 9987). Species from the Persian Gulf and Oman Sea has a max size of 750 cm TL (Ref. 47613).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00398 (0.00256 - 0.00619), b=3.15 (3.02 - 3.28), based on LWR estimates for species & Subfamily-BS (Ref. 93245).
Trophic Level (Ref. 69278):  4.5   ±0.7 se; Based on diet studies.
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (tm=4-11; tmax=50; Fec = 10).
Vulnerability (Ref. 59153):  High vulnerability (64 of 100) .
Price category (Ref. 80766):   Medium.
