Longcomb sawfish
The longcomb sawfish is native to tropical and subtropical waters in the western and central Indo-Pacific. Historically its distribution covered almost and it ranged from South Africa, north to the Red Sea and Persian Gulf, east to the South China Sea, through Southeast Asia to Australia. In Australia, it ranged from Shark Bay, along the northern part of the country, and south to Jervis Bay on the eastern coast. Today it has disappeared from much of its historical range. It can live in colder waters than its relatives, as also evident by the range in Australia where it occurs further south than the other species of sawfish.
Dwarf sawfish
This sawfish feeds mainly on fish, but also eats molluscs and crustaceans. The rostrum has large numbers of pores adapted for electroreception and is probably also used to manipulate prey. Its sensory input helps the fish move about in the muddy waters in which it often lives. Although they are sometimes found in deep water, most movements take place while the tide is either rising or falling, and movements during each tidal cycle may be up to . At high tide the fish tend to forage and rest among the mangroves.
