Short description Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 14-16; Anal spines: 2; Anal soft rays: 12 - 14. Diagnosis: Body and median fins generally brown to nearly black; body paler ventrally; fins grading to smoky gray distally. Margin of scales on sides with blackish streak, appearing as series of transverse bands; few small blue spots scattered on head and sides. Pelvic and anal fins bright blue anteriorly. Lips dusky brown (Ref. 510). Body depth 1.7-2.2 in SL (Ref. 90102).

Biology     Glossary (e.g. epibenthic)

Adults occur close to shore in rocky or dead reef areas where visibility is often reduced due to silting and wave action. Territorial, they maintain and 'weed' filamentous algae patches growing on dead coral (Ref. 9710). 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 based on models

Preferred temperature (Ref. 123201): 25 - 29.3, mean 28.4 °C (based on 2607 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01950 (0.00922 - 0.04124), b=3.00 (2.82 - 3.18), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.0   ±0.00 se; based on food items.
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).
Nutrients (Ref. 124155):  Calcium = 112 [54, 187] mg/100g; Iron = 0.76 [0.45, 1.33] mg/100g; Protein = 18 [17, 19] %; Omega3 = 0.0924 [, ] g/100g; Selenium = 19.9 [10.5, 41.5] μg/100g; VitaminA = 83.8 [19.2, 330.9] μg/100g; Zinc = 2.06 [1.35, 3.15] mg/100g (wet weight);
