Historically, the Grey Nurse Shark is regarded as having a broad inshore distribution, primarily in subtropical to warm temperate waters around the main continental landmasses, except in the eastern Pacific off North and South America (Compagno 1984a). In the Western Atlantic, this shark occurs from the Gulf of Maine to Florida (USA), in the northern Gulf of Mexico, around the Bahamas and at Bermuda, and also from southern Brazil to northern Argentina. In the eastern Atlantic it is found from the Mediterranean to the Canary Islands, at the Cape Verde Islands, along the coasts of Senegal and Ghana, and from southern Nigeria to Cameroon. In the western Indian Ocean it ranges from South Africa to southern Mozambique, but does not occur around Madagascar. This species has also been reported from the Red Sea and may occur as far east as India (where it appears to have been referred to as C. tricuspidatus; see Compagno 1984a). In the western Pacific, it has been reported from Japan and Australia, but not New Zealand (Last and Stevens 1994).
