Short description Morphology | Morphometrics

Dorsal spines (total): 13 - 14; Dorsal soft rays (total): 10; Anal spines: 7; Anal soft rays: 9 - 10; Vertebrae: 23. Coloration highly variable; influenced by substrate's color and mood of the fish.

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01773 (-0.11870 - 0.15415), b=3.01625 (2.93528 - 3.09721), based on LWR estimates for species & genus-BS (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 (tmax=2.5).

Vulnerability (Ref. 59153): Low vulnerability (24 of 100) .

Price category (Ref. 80766): High.
