Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 14 - 18; Dorsal soft rays (total): 8 - 11; Anal spines: 1; Anal soft rays: 18 - 21. Red and orange, marbled with white, broad orange or red bar on caudal peduncle of female, black head "mask" and caudal peduncle in male, and reddish caudal fin. Head, chest, and pectoral-fin base scaleless; tiny orbital tentacle; mandibular pores 3-4 + 1 + 3-4. Maximum size to 4.4 cm TL (Ref. 90102).

Adults inhabit rock and coral reefs at 7 m or shallower (Ref. 90102). 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).

Estimates based on models

Preferred temperature (Ref. 123201): 24.7 - 29.3, mean 28.5 °C (based on 1583 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): 3.2 ±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).
