Pointed sawfish (Anoxypristis cuspidata) fish species information

Scientific Name
Anoxypristis cuspidata

Common Name
Pointed sawfish

Biology
Found inshore, often in river deltas and estuaries; penetration well up rivers needs confirmation (Ref. 9859). Common in sheltered bays with sandy bottoms. Feeds on small fish and cuttlefish (Ref. 9859). Ovoviviparous (Ref. 50449). Generally harmless but its saw-like snout may cause serious injury when caught: it is known thrash violently and vigorously (Ref. 9859). Caught for its flesh and liver (which is rich in oil) in some parts of Asia (Ref. 6871). Maximum lengths of up to 610 cm TL are based on unconfirmed reports (Ref. 9859).
