Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 7 - 8; Anal spines: 1; Anal soft rays: 7. This species is distinguished by the following characters: cephalic sensory-canal pore system missing only IT pore (pattern 2); dorsal/anal fin-ray formula 7/7 or 8/7; unbranched pectoral-fin rays; 5th pelvic-fin ray 15.9-16.4% of 4th ray; presence of a narrow dark bar at caudal-fin base; with a red line extending down from under eye to jaws; there are 5 postanal ventral-midline spots associated with subcutaneous bars; 2 distinctive black crescent-shaped marks present underneath the pectoral fin (Ref. 113376).

Biology     Glossary (e.g. epibenthic)

Collected from rubble bottom by clove oil at 13.5 m depth (Ref. 113376).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00708 (0.00333 - 0.01504), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.9   ±0.3 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
