Morphology | Morphometrics
Vertebrae: 129 - 138. Head short and very broad. Body robust with inflatable stomach; with dark, mottled and blotched color pattern, and mostly with a dark median stripe on the belly. Labial furrows absent. Denticles large and widely spaced.
Eastern Indian Ocean: southern Australia, from Western Australia to New South Wales.

Estimates of some properties based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00324 (0.00152 - 0.00691), b=3.10 (2.92 - 3.28), based on LWR estimates for this Subfamily-body shape (Ref. 93245
Trophic Level (Ref. 69278
): 4.3 ±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
): Very high vulnerability (80 of 100) .
