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
Sawfish have a strong shark-like body, a flat underside and a flat head. "Pristis" sawfish have a rough sandpaper-like skin texture because of the covering of dermal denticles, but in "Anoxypristis" the skin is largely smooth. The mouth and nostrils are placed on the underside of the head. There are about 88–128 small, blunt-edged teeth in the upper jaw of the mouth and about 84–176 in the lower jaw (not to be confused with the teeth on the saw). These are arranged in 10–12 rows on each jaw, and somewhat resemble a cobblestone road. They have small eyes and behind each is a spiracle, which is used to draw water past the gills. The gill slits, five on each side, are placed on the underside of the body near the base of the pectoral fins. The position of the gill openings separates them from the superficially similar, but generally much smaller (up to long) sawsharks, where the slits are placed on the side of the neck. Unlike sawfish, sawsharks also have a pair of long barbels on the rostrum ("saw").
