The Indo-Pacific tarpon is a large, silvery fish of the coastal waters of the Indian and Pacific Oceans. The species can reach about 1.5 metres and has a streamlined, laterally compressed body with large scales, large eyes and an upward-pointing mouth; the last dorsal-fin ray is greatly elongated. Adults usually live at sea, while juveniles enter river mouths, bays, mangroves and even fresh inland waters. With a richly vascularised swim bladder the species can gulp air and so tolerate low-oxygen water. It is fished locally and is harmless to humans.
