Entorno: milieu / zona climática / rango de profundidad / gama de distribución
Ecología
marino; salobre demersal; rango de profundidad 1 - 20 m (Ref. 116378). Tropical; 20°N - 25°S, 46°E - 155°E (Ref. 114953)
Indo-West Pacific: tropical Australia, possibly more widely distributed. A nominal record from the Canary Islands may not be this species, but the sketchily known Pristis pristis from the eastern Atlantic is similar and needs comparison to determine if the two species are distinct (Ref. 009859). India (Bay of Bengal), Indonesia to eastern Australia, isolatted record from Réunion (Ref. 114953).

Madurez: Lm ?  range ? - ? cm

Greenish brown, rarely yellowish; white ventrally; fins paler. Body shark-like, pectoral fins distinct; head flattened, with a blade-like snout bearing 18-22 pairs of lateral teeth; blade broad, not tapering distally. Nostrils broad with large nasal flaps. Rostral teeth slender, with a groove along posterior margins; teeth reaching basal quarter of blade. Skin with denticles.
Body shape (shape guide): elongated.
Demersal in shallow coastal inshore habitats in mangrove swamps and embayments (Ref. 114953), intertidal species found in estuaries and on tidal mudflats (Ref. 9859). Ascends brackish areas of rivers (Ref. 9859). Ovoviviparous (Ref. 50449). Pupping thought to occur during the tropical wet season (November to March in Australia (Ref. 114953). Biology little known (Ref. 9859). Males mature at approximately 260 cm TL, females possibly slightly larger; born at 65 cm TL (Ref. 114953). Flesh may be good to eat (Ref. 6871).
