Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8 - 10; Anal spines: 1; Anal soft rays: 8 - 10. Characterized by translucent with broad red to brown, internal midlateral stripe from head to caudal fin base; 3-5 white to yellowish spots posteroventrally above base of anal fin; caudal fin base with presence of diagnostic black hour-glass shaped mark; all pectoral rays unbranched; longitudinal scale series 22-24; ctenoid scales, none on head, nape and base of pectoral fin; separated pelvic fins, thin membrane joining bases; fourth pelvic ray with 4-9 branches; depth of body 5.0-5.6 in SL (Ref. 90102).

Inhabits clear coastal reefs and protected outer reef coral habitats. Usually at moderate depths of 10 meters or more, swimming near sponges or corals when feeding on plankton (Ref. 48637). Hovers in groups above branching corals of protected reefs (Ref. 9710).

Estimates based on models

Preferred temperature (Ref. 115969): 27.1 - 29.3, mean 28.7 (based on 1396 cells).

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): 3.2 ±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).

Price category (Ref. 80766): Very high.
