Korte beschrijving Determinatiesleutels | Morfologie | Morfometrie

Dorsale stekels (totaal) : 6; Dorsale zachte stralen (totaal) : 14; Anale stekels: 3; Anale zachte stralen: 9 - 10; Wervels: 24. Head and body generally dark brownish when fresh. Two indistinct oblique dark bands on body, the first descending from the nape to behind the pectoral fin; the second from base of anterior 2nd or 3rd dorsal fin spines and soft dorsal fin base, curving backward thru the lateral line to soft anal fin and caudal peduncle. Maxillary scales absent. Eye diameter greater than one quarter of the head length. Ten pores on and behind the chin; often with slitlike pores posteriorly. Fleshy lower lip with a cluster of very short dense papillae. At the origin of the dorsal fin is a procumbent spinelike process (exposed tip of first pterygiophore) (Ref. 36944).

Estimates based on models

Preferred temperature (Ref. 123201): 17.6 - 23.2, mean 21.7 °C (based on 14 cells).
Fylogenetische diversiteitsindex (Ref. 82804):  PD50 = 0.5078   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01862 (0.00830 - 0.04177), b=3.01 (2.81 - 3.21), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).
Trofisch niveau (Ref. 69278):  3.9   ±0.6 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 (20 of 100).
