Description

The largetooth sawfish is a giant, shark-like ray of the family Pristidae (sawfishes) reaching about 6.5 metres (now usually treated as a synonym of Pristis pristis). Its most striking feature is the long, flat snout studded on both sides with pairs of large teeth, like a double-edged saw; with it the ray slashes through fish schools and roots prey from the bottom. The body is shark-like with two dorsal fins. The species lives in shallow coastal water, estuaries and the lower reaches of rivers on both sides of the tropical Atlantic and, as a juvenile, runs far into fresh water. Through heavy fishing and habitat loss it has collapsed worldwide and is assessed as Critically Endangered (CR).
