The map depicts the global distribution of 207 freshwater megafauna species, including 130 fishes, 44 reptiles, 31 mammals and 2 amphibians. Fifty-four per cent of all freshwater megafauna species are threatened due to intense human pressure as high exploitation and increasing threats from dam construction.
