Spots or blotches on body form reticulations and crossbands; paler ventrally. Gill membranes ventrally free from the isthmus. Posterior otic sensory canal pore present. Cephalic sensory canal pores not pigmented.
Body shape (shape guide): elongated; Cross section: compressed.

Biology     Glossary (e.g. epibenthic)

Inhabits coastal waters, often in brackish conditions (Ref. 48636). Found hidden amongst rocks or coral rubble (Ref. 48636). Reproductive activity appears to be cyclical and the species may not be a protogynous hermaphrodite (Ref. 2077). Also found in coral reefs among crevices (Ref 90102).

(Ref. 82804) 		PD50 = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic level
(Ref. 69278) 		4.0   ±0.67 se; based on food items.
Resilience
(Ref. 120179) 		Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).
Fishing Vulnerability
(Ref. 59153) 		Moderate vulnerability (44 of 100). 🛈
