The Great Hammerhead, Sphyrna mokarran, is listed as ‘ENDANGERED’ on the IUCN Red List of Threatened SpeciesTM. This large shark ranges widely throughout the tropical waters of the world, including the Atlantic, Pacific and Indian Oceans, and many smaller seas.
The Great Hammerhead is highly prized for its fins, and suffers very high levels of incidental mortality in other fisheries for tuna and tuna-like fishes. Like most other sharks, its slow growth and low reproduction rate makes it highly vulnerable to overexploitation. As a result, it has suffered serious declines, especially in parts of the eastern Atlantic where fishing effort is unmanaged and unmonitored.
The Great Hammerhead is in urgent need of coordinated conservation efforts involving the management of target and non-target fisheries. Fortunately, the increasing recognition of the detrimental effects of shark finning has led to the implementation of finning bans by fishing states in the United States, Australia and the European Union. Nevertheless, improved enforcement of legislation is required to prevent ongoing illegal finning activities.
