Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 15 - 16; Dorsal soft rays (total): 9 - 10; Anal spines: 3; Anal soft rays: 6 - 8. Diagnosis: dorsal fin membrane pale, without dense black band; no strongly marked vertical bars on flanks; caudal of males with some rows of dark to reddish maculae but these never extend over entire fin; normally no markings on flanks, although stressed individuals sometimes with 2 horizontal bands; no blue iridescence on cheeks, opercle and anterior body (Ref. 81260).

Biology     Glossary (e.g. epibenthic)

Pair-bonding, ovophilic mouthbrooder (Ref. 52307, 81260) with delayed uptake (Ref. 81260). Spawns on open substrates; both parents brood offspring (Ref. 81260).

Estimates based on models

Phylogenetic diversity index (Ref. 82804):  PD50 = 0.5156   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01445 (0.00674 - 0.03099), b=2.99 (2.82 - 3.16), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trophic level (Ref. 69278):  3.3   ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179):  Medium, minimum population doubling time 1.4 - 4.4 years (Assuming Fec<1000).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (10 of 100).
