Short Description
A heavily-bodied sawfish with a short but massive saw which is broad-based, strongly tapering and with 14-22 very large teeth on each side; space between last 2 saw-teeth on sides less than 2 times space between first 2 teeth [536]. Pectoral fins high and angular, 1st dorsal fin mostly in front of pelvic fins, and caudal fin with pronounced lower lobe [536]. Greenish, grey or golden-brown above, cream below [536].

Indo-West Pacific: East Africa to New Guinea, north to the Philippines and Viet Nam, south to Australia. Also Atlantic and eastern Pacific if Pristis perotteti and Pristis zephyreus are synonymized with this species. The original description of Pristis microdon did not give a locality, but most authors have used the name Pristis microdon for the Indo-West Pacific sawfishes of this species group as contrasted from the Atlantic Pristis perotteti and the eastern Pacific Pristis zephyreus.
