Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 0; Dorsal soft rays (total): 0; Anal spines: 0; Anal soft rays: 0; Vertebrae: 121 - 133. Body light brown, with dendritic pattern. Corner of mouth with a dark brown spot, preceded on lower lip by a large white blotch (often followed by another above and behind corner of mouth); upper and lower jaw pores usually in prominent white spots. Vertebrae 121-133.

Occurs in shallow coastal reef flats, usually found in less than 5 m water depth, but ranges to deep water rubble reefs (Ref. 48635). Benthic (Ref. 58302). Minimum depth reported taken from Ref. 86942.

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=0.00054 (0.00036 - 0.00081), b=3.24 (3.12 - 3.36), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.9 ±0.6 se; based on size and trophs of closest relatives

Resilience (Ref. 120179): Medium, minimum population doubling time 1.4 - 4.4 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (40 of 100).
