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.

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5234   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00490 (0.00193 - 0.01241), b=3.05 (2.83 - 3.27), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.8   ±0.6 se; Based on size and trophs of closest relatives
Widerstandsfähigkeit (Ref. 69278):  niedrig, Verdopplung der Population dauert 4,5 - 14 Jahre. (Fec assumed to be <100).
Verwundbarkeit (Ref. 59153):  High to very high vulnerability (71 of 100) .
