Short description Morphology | Morphometrics

Dorsal spines (total): 13 - 14; Dorsal soft rays (total): 11-12; Anal spines: 2; Anal soft rays: 11 - 12. This species is distinguished by the following: Dorsal rays XIII-XIV, 11-12, usually XIV, 12; anal rays II, 11-12, usually 12; pectoral rays 18; spiniform caudal rays 3; tubed lateral-line scales 15-17; gill rakers 7 + 20-21 (total 27-28); body depth 1.84-1.99 in SL. Color of the adults when fresh is dull brownish yellow with nine thin lavender-gray stripes on the side of body; a prominent black spot on dorsal half of pectoral-fin base (Ref. 59379).

Biology     Glossary (e.g. epibenthic)

Adults inhabit deep outer-reef slopes at depths of 85-120 m, usually in the vicinity of rock outcrops with small holes and caves, and around limestone talus; usually found in small groups and observed feeding low in the water column (Ref. 59379). Oviparous, distinct pairing during breeding (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205).

Estimates of some properties based on models

Preferred temperature (Ref. 115969): 12.8 - 27.4, mean 25.2 (based on 5 cells; Ref. 115970).
Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01778 (0.00793 - 0.03989), b=3.00 (2.83 - 3.17), in cm Total Length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic Level (Ref. 69278):  3.0   ±0.1 se; Based on size and trophs of closest relatives
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (22 of 100) .
