Short description Claves de identificación | Morfología | Morfometría

Espinas dorsales (total) : 12; Radios blandos dorsales (total) : 15 - 16; Espinas anales: 2; Radios blandos anales: 13 - 14.

Adults inhabit coral and rocky reefs (Ref. 7247). A protogynous hermaphrodite (Ref. 55367). Feeds on zooplanktons (Ref. 89972). 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). Diurnal species (Ref. 54980; 113699).

Life cycle and mating behavior Madurez | Reproducción | Puesta | Huevos | Fecundidad | Larva

Forms permanent harem groups composed of a single male and several smaller females (Ref. 55367). A monandric species (Ref. 55367). Oviparous (Ref. 205). Eggs are demersal and adhere to the substrate (Ref. 205). Males guard and aerate the eggs (Ref. 205). While protogyny was originally proposed for this species such as the report of length at sex change = 6.8 cm TL (Ref. 55367), recent studies confirmed gonochorism in the form of non-functional hermaphroditism (Ref. 103751).

Estimates based on models

Preferred temperature (Ref. 123201): 24.5 - 28.5, mean 27.3 °C (based on 142 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5005 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.02089 (0.00944 - 0.04623), b=2.98 (2.80 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Nivel trófico (Ref. 69278): 3.0 ±0.2 se; based on size and trophs of closest relatives

Resiliencia (Ref. 120179): Alto, población duplicada en un tiempo mínimo inferior a 15 meses (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
