Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 11; Dorsal soft rays (total): 13 - 15; Anal spines: 4; Anal soft rays: 12 - 13. Fins are uniformly red and lack white leading edges or darker tips.

Inhabits reef flats and seaward slopes to depths of more than 52 m where it is found in groups in caves and under ledges (Ref. 1602). Benthopelagic (Ref. 58302). Feeds mainly on polychaetes, also on crab megalops, hermit crab larvae, and larvae of alpheid shrimps (Ref. 12419). Forms large schools in oceanic locations (Ref. 48635).

Estimates based on models

Preferred temperature (Ref. 115969): 24.5 - 28.7, mean 26.5 (based on 45 cells).

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

Bayesian length-weight: a=0.02089 (0.01283 - 0.03402), b=3.08 (2.94 - 3.22), in cm Total Length, based on LWR estimates for this species & Genus-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.6 ±0.2 se; based on diet studies.

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

Fishing Vulnerability (Ref. 59153): Moderate vulnerability (37 of 100).

Price category (Ref. 80766): Medium.
