Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 9; Dorsal soft rays (total): 29 - 33; Anal spines: 3; Anal soft rays: 26 - 29. Dark brown, nearly black in color. Erectile spine (sharp and forward-pointing) on each side of caudal peduncle which folds down into a groove. Mouth small, snout noticeably extended. Light blue ring around chin and presence of spot of same color on gill cover at angle of gill opening. Dorsal fin with soft part having longer base than spinous part. Juveniles lack the large orange spot on caudal area.

Biology     Glossary (e.g. epibenthic)

Occurs in clear seaward reefs, usually in groups (Ref. 9710). Benthopelagic (Ref. 58302). Feeds on filamentous and small fleshy algae (Ref. 9267). Monogamous (Ref. 52884). Spine in caudal peduncle may be venomous. Size of metamorphosis from postlarva stage to juvenile is 6 cm (Ref. 9267). This species sometimes hybridizes with A. nigricans (Ref. 9808).

Life cycle and mating behavior Maturities | Reproduction | Spawnings | Egg(s) | Fecundities | Larvae

Monogamous mating is observed as both facultative and social (Ref. 52884).

Estimates based on models

Preferred temperature (Ref. 123201): 25.8 - 28.3, mean 27.4 °C (based on 404 cells).
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):  2.0   ±0.00 se; based on food items.
Resilience (Ref. 120179):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
