Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 12 - 13; Anal spines: 2; Anal soft rays: 12 - 13.

Adults inhabit inshore rocky reefs and weed beds (Ref. 7247). 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).

Estimates based on models

Preferred temperature (Ref. 123201): 24.6 - 27.7, mean 26.9 °C (based on 255 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01259 (0.00571 - 0.02773), b=3.03 (2.84 - 3.22), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 2.6 ±0.29 se; based on food items.

Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).

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

Chromis dasygenys (Fowler, 1935)
