Based upon capture-records or other indices of its abundance, known or suspected Centres of Abundance are considered here (in no specific order) as the shelf waters of Southern Africa (particularly from Namibia to Natal); Eastern, Western and particularly Southern Australia; New Zealand; the Japanese archipelago; the North-eastern seaboard of North America, especially Long Island and environs; the Pacific coast of North America, primarily from Oregon to Baja; the coasts of southern Mexico, Central Chile; the Mediterranean Sea, primarily the Western-Central region, Sicilian Channel and Tyrrhenian Sea.
It is stressed, however, that white sharks occur less frequently at many sites elsewhere (e.g., Brazil, Caribbean, Azores, Hawaii, North-West Africa; Philippines; Sri Lanka; Seychelles, Gough Island, Chatham Islands, etc.) and that periodicity and movements are poorly understood. Limited trans-equatorial movement between temperate areas, across equatorial waters by means of tropical submergence into cooler, deeper water, is suspected.
