Tarpons are fish of the genus Megalops. They are the only members of the family Megalopidae. Of the two species, one (M. atlanticus) is native to the Atlantic, and the other (M. cyprinoides) to the Indo-Pacific Oceans. The two species of tarpons are M. atlanticus (Atlantic tarpon) and M. cyprinoides (Indo-Pacific tarpon). M. atlanticus is found on the western Atlantic coast from Virginia to Brazil, throughout the Caribbean and the coast of the Gulf of Mexico. Tarpons are also found along the eastern Atlantic coast from Senegal to South Angola. M. cyprinoides is found along the eastern African coast, throughout Southeast Asia, Japan, Tahiti, and Australia. Both species are found in both marine and freshwater habitats, usually ascending rivers to access freshwater marshes. (Source: Wikipedia.org, CC BY-SA)
