Short description Morphology | Morphometrics

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.

Distribution Countries | FAO areas | Ecosystems | Occurrences | Introductions | 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.

Biology     Glossary (e.g. epibenthic)

Inshore and intertidal species found in estuaries and on tidal mudflats (Ref. 9859). Ascends brackish areas of rivers (Ref. 9859). Ovoviviparous (Ref. 50449). Biology little known (Ref. 9859). Flesh may be good to eat (Ref. 6871).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5312   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00501 (-0.19894 - 0.20895), b=3.05 (2.94 - 3.16), based on LWR estimates for this family-BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.7   ±0.6 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  Low, minimum population doubling time 4.5 - 14 years (Fec assumed to be <100).
Vulnerability (Ref. 59153):  Moderate to high vulnerability (50 of 100) .
Price category (Ref. 80766):   Medium.
