Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 14 - 16; Dorsal soft rays (total): 9 - 10; Anal spines: 1; Anal soft rays: 16 - 19. Semi-transparent with indistinct oblique pale and dusky bands on the body (Ref. 48636). Males are heavily pigmented under the head.

Adults inhabit shallow coastal to outer reef crests and slopes but reported to 30 m depth (Ref. 48636). Also found in high isolated tidal pools and wave-swept tops of lagoon reefs (Ref. 1602). Occasionally found in intertidal pools. Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). Minimum depth of 0 m reported from Ref. 90102.

Estimates based on models

Preferred temperature (Ref. 123201): 28.3 - 29.1, mean 28.8 °C (based on 485 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00617 (0.00288 - 0.01322), b=3.04 (2.86 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.1 ±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).
