Korte beschrijving Morfologie | Morfometrie

Dorsale stekels (totaal): 0; Dorsale zachte stralen (totaal): 18-25; Anale stekels 0; Anale zachte stralen: 21 - 27; Wervels: 27 - 30. Two apomorphic color patterns, body bright gray with dark gray to black stripes in males (versus light gray or no stripes; stripes wider than the light interspaces) and a vertically paired black blotch on caudal peduncle of juveniles and females (versus small spots irregularly arranged, or a single round dorsally positioned spot, or no spots on caudal peduncle). Second pharyngobranchial teeth 6-7 and adult males with a rather deep body which sometimes forms a discoid body morphology. Supraorbital neuromasts 16-19, scales on longitudinal series 26-28. Dorsal fin origin anterior to anal fin origin, caudal fin rays 22-25. Caudal fin rounded.

Estimates based on models

Fylogenetische diversiteitsindex (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00891 (0.00396 - 0.02008), b=3.14 (2.94 - 3.34), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisch niveau (Ref. 69278): 3.2 ±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 (10 of 100).
