Description

The largetooth sawfish is a large, ray-like sawfish (Pristidae) from coastal, brackish and fresh water of the tropical Indo-Pacific that ascends far up rivers and lakes. The species can reach about 7 metres and has an elongate, shark-like body with a long, flat snout set with pairs of large, sideways-projecting teeth, with which it strikes prey fish and stirs the bottom. Through overfishing and habitat loss the species is critically endangered. Not aggressive, but the saw can cause serious injuries in defence or in nets.
