Short description Morphology | Morphometrics

Dorsal spines (total): 7; Dorsal soft rays (total): 8-9; Anal spines: 1; Anal soft rays: 8 - 9. Characterized by golden brown body color; white on lower head and ventral body; presence of lavender or bluish lateral stripe from upper eye to middle of caudal peduncle; caudal fin base with large dark blotch; elongate and filamentous second dorsal spine; all pectoral rays unbranched; fifth pelvic ray unbranched; longitudinal scale series 25-26; predorsal scales about 12; cheek and opercle without scales; depth of body about 4.0-4.4 in SL (Ref. 90102).

Inhabits coastal to outer reefs, typically in small groups in caves (Ref. 48637). Forms loose aggregations associated with shallow pockets and caves of steep drop-offs. Hovers in a head-up position (often vertical, posture in the water column) and feeds on copepods (Ref. 1602, 58123).

Estimates of some properties based on models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00419 - 0.01894), b=3.07 (2.90 - 3.24), based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic Level (Ref. 69278): 3.0 ±0.00 se; Based on food items.

Resilience (Ref. 69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

Vulnerability (Ref. 59153): Low vulnerability (10 of 100) .
