  • side of nape - black spot
  • head and lower body: many dark dots
Dorsal rays XVIII to XX, 9-12 (usually XIX, 11); anal rays II, 18-20 (usually 19); pectoral rays 13-15 (usually 14); lateral-line scales 53-61; no scales on midline in front of dorsal fin, present on breast of males only, and sometimes present on the prepectoral area; jaws with single row of large conical teeth; roof of mouth with teeth at front but not sides; cirri present on nostrils, above eye, and on nape.

A double row of dark greenish-brown blotches on side; head and lower half of body with numerous dark spots; a black pupil sized spot on side of nape.

Estimates based on models

Preferred temperature (Ref. 123201 ): 22.3 - 29.1, mean 26.1 °C (based on 230 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00912 (0.00399 - 0.02083), b=3.06 (2.87 - 3.25), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.5   ±0.4 se; based on size and trophs of closest relatives Fishing Vulnerability (Ref. 59153 ):  Low vulnerability (10 of 100). Nutrients (Ref. 124155 ):  Calcium = 122 [67, 225] mg/100g; Iron = 0.805 [0.483, 1.319] mg/100g; Protein = 18.8 [17.7, 19.8] %; Omega3 = 0.164 [0.095, 0.274] g/100g; Selenium = 20 [10, 39] μg/100g; VitaminA = 209 [68, 636] μg/100g; Zinc = 2.15 [1.46, 3.04] mg/100g (wet weight);
