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

Western Pacific: Kapingamarangi Atoll, Caroline Islands. Possibly endemic of that atoll. Reports from other areas are likely misidentifications of the juvenile stages of Acanthurus pyroferus (J.E. Randall, pers. comm.), e.g. from Taiwan (Shao et al., 2008).

Size / Weight / Age

Maturity: Lm ?  range ? - ? cm
Max length : 28.0 cm TL male/unsexed; (Ref. 37792)

Short description Morphology | Morphometrics

Dorsal spines (total): 8; Dorsal soft rays (total): 26; Anal spines: 3; Anal soft rays: 24. Caudal fin lunate. Life colour unknown. Preserved specimen is dark brown with two small oval spots, one above and the other slightly behind the upper end of the gill opening, and a dark brown band at the base of the dorsal fin.

Biology     Glossary (e.g. epibenthic)

Found over sand and coral bottoms of clear channels (Ref. 9710). Juveniles probably occur on reef flats (Ref. 9710). Rare and not commercial (J.E. Randall, pers. comm.).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.02344 (0.01103 - 0.04981), b=2.96 (2.79 - 3.13), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278):  2.2   ±0.1 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (18 of 100).
