Of the entire family of hammerhead sharks, the common hammerhead is the most tolerant to the temperate zone, and is found all over the world at higher latitudes than any other kind of hammerhead sharks. In the Atlantic Ocean, it occurs from Nova Scotia to the Virgin Islands, from Brazil to the south of Argentina to the west, from the British Isles to Côte d’Ivoire, including the Mediterranean Sea, to the east. Sometimes he goes to the Black Sea. In the Indian Ocean, an ordinary hammerhead shark inhabits the coasts of South Africa, India and Sri Lanka.
In the western part of the Pacific Ocean, it extends from the Tonkin Gulf to southern Japan and Siberia, as well as off the coast of Australia and New Zealand. In the central and eastern Pacific Ocean it meets the Hawaiian and Galapagos Islands, the coasts of California, Panama, Ecuador and Chile. This species, as a rule, does not live in tropical waters, although there are rare cases of finding an ordinary shark-hammer, for example, in Mannar Bay in India and in the south of Mozambique. Its presence in the tropics is difficult to determine due to confusion with other types of hammerhead sharks.
In comparison with the round-hammer-fish and the giant shark-hammer, the ordinary hammer-shark keeps closer to the surface at a depth of less than 20 m. Nevertheless, there is evidence that this species can sink to a depth of up to 200 m. Ordinary hammerhead sharks Prefer coastal waters, bays and estuaries of rivers, but are sometimes found in the open ocean, on the continental shelf and around the oceanic islands. There is evidence of the presence of this shark in freshwater (for example, Indian River in Florida). In summer, they migrate to the poles to stay in cool water, and in winter return to the equator.
