Morphology | Morphometrics
spines: 0. Diagnosis: adipose fin large, its origin close to dorsal fin; pigmentation not in a banded pattern, colour pattern striking with varied dark brown patches and spots with clear white interspaces, caudal fin clear with narrow black bands; eyes widely spaced (interorbital width 2.3-3.7 times orbit diameter); origin of dorsal base less than head length behind head; dorsal base before origin of pelvic fins; dorsal fin rectangular with leading (simple) ray shorter than length of leading edge; caudal fin with 6+7 principal rays; caudal peduncle compressed, short, 5.7-6.4 times in SL, slightly longer than deep (length 1.3-1.5 times depth); snout long, half of head length; eyes placed equidistant from hind margin of head and tip of snout (mid-way along head)(Ref. 81646).

Estimates based on models
Phylogenetic diversity index (Ref. 82805
= 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01000 (0.00244 - 0.04107), b=3.04 (2.81 - 3.27), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.0 ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec < 10,000).
Vulnerability (Ref. 59153
): Low to moderate vulnerability (32 of 100) .
