Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 14 - 15; Dorsale zachte stralen (totaal) : 14 - 16; Anale stekels: 3; Anale zachte stralen: 10 - 11. Diagnosis: lower pharyngeal bone about as long as broad, with anterior lamella shorter than toothed area; median pharyngeal teeth broadened when compared to lateral teeth; 3-4 series of scales on cheeks; 4-4.5 scales between first dorsal fin spine and upper lateral line (Ref. 53405). Dark vertical bars narrower than lighter inter-spaces (Ref. 52307, 53405).

Probably pair-bonding, open substratum spawner, with both parents guarding the brood (Ref. 52307).

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01905 (0.00827 - 0.04391), b=3.01 (2.82 - 3.20), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.5 ±0.4 se; based on size and trophs of closest relatives

Weerstandsvermogen (Ref. 120179): Hoog, minimale populatieverdubbelingstijd minder dan 15 maanden (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (15 of 100).
