Circumglobal in tropical and warm temperate seas. Western Atlantic: New York, USA through the Caribbean to central Brazil. Eastern Atlantic: Senegal to Gulf of Guinea; St. Paul's Rocks (Ref. 13121). Indian Ocean: throughout the region, including the Red Sea and the Persian Gulf. Western Pacific: Japan to Australia and Hawaii. Eastern Pacific: California, USA to Chile. Identified as one of the species with an unfavorable conservation status in Appendix II of the Bonn Convention for the Conservation of Migratory Species of Wild Animals in 1999. Classified as a highly migratory species, in Annex I of the 1982 United Nations Convention on the Law of the Sea (UNCLOS) which called for 'coordinated management and assessment to better understand cumulative impacts of fishing effort on the status of the shared populations' of these sharks (Ref. 26139). Included in Appendix II of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) since May 2003 which regulates international trade of this species. This can partially implement the original objective of the FAO International Plan of Action for the Conservation and Management of Sharks (IPOA-Sharks). However, international trade still exists.
