Morphology | Morphometrics
(total): 13 - 14;
soft rays: 8;
Vertebrae: 26. This species is distinguished by the following characters: Dorsal fin with usually 13 spiny rays, 10 soft rays, with the anterior 4 spines forming a separate lobe; A II,8; P 13; vertebrae 26, with 4 praeopecular spines; vomer with teeth; presence of developed papillae on cheeks, lower surface of the head and on the maxillare plate; isthmus whose apex, by far, does not reach the level of the fifth mandibular pore. This species is represented by a dark morph and a light morph (Ref. 86262).
This species, by all probability, keeps at gravel sites at the boundary of the coral reef and of sands on coral banks (Ref. 86262).

= 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
): 3.3 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months ().
Vulnerability (Ref. 59153
): Low vulnerability (10 of 100) .
