Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Indo-Pacific: Somalia (Ref. 30573 ) and South Africa (Ref. 4392 ) to the Line, Marquesan, and Tuamoto islands, north to southern Japan, south to Rowley Shoals, northern New Zealand and Lord Howe and Rapa islands.

Size / Weight / Age

Maturity: L m   ?   range ? - ? cm
Max length : 16.0 cm SL male/unsexed; (Ref. 9823 )

Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 13; Anal spines : 3; Anal soft rays : 10 - 11. Juveniles easily identified by the color pattern and rounded snout. Males become brightly colored and head usually green with a yellow band following on the body (Ref. 48636 ). Head naked, no scales dorsally on opercle. Initial phase with a broad blackish stripe from snout through eye to caudal-fin base (Ref 9823).

Biology     Glossary (e.g. epibenthic)

Occurs in aggregations over shallow lagoon and seaward reefs (Ref. 9710 ) and on reef flats (Ref. 9823 ). Feeds mainly on crustacean zooplankton (Ref. 1602 ). Spawns at dusk above reefs (Ref. 90102 ). Rarely marketed (Ref. 2334 ). Minimum depth reported taken from Ref. 128797.

Life cycle and mating behavior Maturity | Reproduction | Spawning | Eggs | Fecundity | Larvae

Estimates based on models

Preferred temperature (Ref. 123201 ): 24.8 - 29.3, mean 28.4 °C (based on 3194 cells). Phylogenetic diversity index (Ref. 82804 ):  PD 50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high]. Bayesian length-weight: a=0.00933 (0.00521 - 0.01670), b=3.07 (2.92 - 3.22), in cm total length, based on LWR estimates for this species & Genus-body shape (Ref. 93245 ). Trophic level (Ref. 69278 ):  3.1   ±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 ):  Low vulnerability (10 of 100). Nutrients (Ref. 124155 ):  Calcium = 57.7 [23.1, 122.2] mg/100g; Iron = 0.812 [0.431, 1.709] mg/100g; Protein = 18.8 [15.9, 21.1] %; Omega3 = 0.203 [0.107, 0.398] g/100g; Selenium = 9.28 [4.34, 20.90] μg/100g; VitaminA = 140 [38, 589] μg/100g; Zinc = 1.18 [0.73, 2.12] mg/100g (wet weight);
