Short description Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 18-20; Anal spines: 2; Anal soft rays: 12 - 13. This species is distinguished by the following set of characters: D IX,18-20; A II,12-13; pectoral rays 17-18; tubed lateral line scales 33-48; gill rakers 5-6 + 11-12; opercular spinules 8-11; body depth 2.2-2.6 in SL; color generally pinkish brown, usually grading to yellowish or orange on lower side of body including abdomen; white stripe on midline of snout extending posteriorly on forehead and along base of dorsal fin; fins whitish to semi-translucent (Ref. 85605).

Biology     Glossary (e.g. epibenthic)

This species is generally commensal with the anemone Heteractis magnificus (Quoy & Gaimard, 1833) at depths between about 4-10 m (Ref. 85065). 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

Phylogenetic diversity index (Ref. 82805):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01122 (0.00514 - 0.02450), b=3.04 (2.87 - 3.21), in cm Total Length, based on all LWR estimates for this body shape (Ref. 93245).
Trophic Level (Ref. 69278):  2.8   ±0.3 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 (12 of 100) .
