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
Old stories often describe sawfish as highly dangerous to humans, sinking ships and cutting people in half, but today these are considered myths and not factual. Sawfish are actually docile and harmless to humans, except when captured where they can inflict serious injuries when defending themselves by thrashing the saw from side-to-side. The saw is also used in self-defense against predators such as sharks that potentially may eat sawfish. In captivity they have been seen using their saws during fights over hierarchy or food.
