Short description Morphology | Morphometrics

Dorsal spines (total): 12; Dorsal soft rays (total): 14-17; Anal spines: 2; Anal soft rays: 13 - 15. Exhibits geographic color variations (Ref. 7247). Body dark in front, becoming abruptly yellow between last dorsal spine and anal fin origin (Ref. 26938).

Biology     Glossary (e.g. epibenthic)

Adults inhabit shallow coral reefs and isolated patch reefs in deeper water. Feed primarily on algae but also on polychaetes, hydroids, copepods and ascidians (Ref. 9626). Aggressively territorial but only around a small area (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). Taken incidentally in traps and small-meshed beach nets (Ref. 5217).

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

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). This species has a juvenile bisexual condition and a typical gonochore testis (Ref. 103751).

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=0.01479 (0.00779 - 0.02808), b=3.01 (2.85 - 3.17), in cm Total Length, based on LWR estimates for this species & (Sub)family-body (Ref. 93245).
Trophic Level (Ref. 69278):  2.0   ±0.00 se; Based on food items.
Resilience (Ref. 69278):  High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153):  Low vulnerability (21 of 100) .
