Knifetooth sawfish can grow to be 15ft long. Furthermore, the pollution from these activities degrades the water quality. Coastal development, coastline urbanisation, and an expanding mining industry result in the modification and destruction of critical habitat. Two toothed jaws of a knifetooth sawfish, Anoxypristis cuspidata (LATHAM, 1794), which also lives off the coast of New Guinea. Discover (and save!)

[10], On September 10, 2010, WildEarth Guardians petitioned the US National Marine Fisheries Service (NMFS) to list six sawfish species - the Narrow Sawfish; the Dwarf Sawfish, the Freshwater Sawfish, the Common Sawfish, the Narrowsnout Sawfish, and the Smalltooth Sawfish - as endangered or threatened under the Endangered Species Act.
