Korte beschrijving Morfologie | Morfometrie

Greyish above, pale below; fins usually pale. Body shark-like, pectoral fins distinct; head flattened, with a blade-like snout bearing 18-22 pairs of lateral teeth; blade slender, not tapering distally. Nostrils very narrow with small nasal flaps. Rostral teeth short, flattened, broadly triangular, lacking a groove along posterior margins; no teeth on basal quarter of blade. Adults with widely spaced denticles, young with naked skin.

Biologie     Verklarende woordenlijst (b.v. epibenthic)

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).

Life cycle and mating behavior Geslachtsrijpheid | Voortplanting | Kuitschieten | Eieren | Fecundity | Larven

Ovoviviparous. Litter size from 6 to 23, young born in the spring (Ref. 9859).
