In Australia, only two rays, Pristis microdon (freshwater sawfish) and Himantura chaophraya (freshwater whipray), and three sharks Carcharhinus leucas (bull shark), Glyphis sp. A (speartooth shark) and Glyphis sp. C (northern river shark), occur in oligohaline environments of the upper reaches of rivers far from the coast. While information on the occurrence, biology and distribution of these ‘freshwater’ species remains limited, recent surveys of rivers throughout northern Australia by Thorburn et al. (2003), and Morgan et al. (2002, in press) documenting the inland fishes of the Fitzroy River, have identified the Fitzroy River, Western Australia, as a significant habitat for several of these rare species.
