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.
Sawfish
Relatively little is known about the reproductive habits of the sawfish, but all species are ovoviviparous with the adults females giving birth to live young once a year or every second year. In general, males appear to reach sexual maturity at a slightly younger age and smaller size than females. As far as known, sexual maturity is reached at an age of 7–12 years in "Pristis" and 2–3 years in "Anoxypristis". In the smalltooth and green sawfish this equals a total length of , in the largetooth sawfish at , in the dwarf sawfish about , and in the narrow sawfish at . This means that the generation length is about 4.6 years in the narrow sawfish and 14.6–17.2 years in the remaining species.
