Environment: milieu / climate zone / depth range / distribution range Ecología

marino; salobre demersal; rango de profundidad 1 - 20 m (Ref. 116378). Tropical; 20°N - 25°S, 46°E - 155°E (Ref. 114953)

Distribución Países | Áreas FAO | Ecosistemas | Ocurrencias, apariciones | Point map | Introducciones | Faunafri

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).

Short description Claves de identificación | Morfología | Morfometría

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.

Biología     Glosario (por ej. epibenthic)

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).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5234   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (0.00198 - 0.01270), b=3.05 (2.83 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Nivel trófico (Ref. 69278):  3.8   ±0.6 se; based on size and trophs of closest relatives
Resiliencia (Ref. 120179):  Bajo, población duplicada en un tiempo mínimo de 4.5-14 años (Fec assumed to be <100).
Fishing Vulnerability (Ref. 59153):  Very high vulnerability (90 of 100).
