Indo-Pacific: East Africa to southeastern Oceania and from Australia northward to Japan. This species has been referred to as Gymnocranius robinsoni in recent literature.

Biology     Glossary (e.g. epibenthic)

Inhabits offshore reefs (Ref. 9710), trawling grounds of the continental shelves and offshore rocky bottoms (Ref. 30573). Juveniles inshore on muddy substrates (Ref. 48635). Solitary or in small groups (Ref. 90102). Feeds mostly on bottom invertebrates and small fishes (Ref. 30573). Potential commercial fish if sufficient stocks can be located (Ref. 9775). Marketed fresh (Ref. 9775); sometimes with a strong and unpleasant flavor (Ref. 11888).

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5039   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.01124 - 0.03382), b=2.89 (2.74 - 3.04), based on LWR estimates for species & Subfamily-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.4   ±0.5 se; Based on diet studies.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (K=0.23).
Vulnerability (Ref. 59153):  Moderate vulnerability (42 of 100) .
Price category (Ref. 80766):   High.
