Description synthétique Clés d'identification | Morphologie | Morphométrie

Épines dorsales (Total) : 0; Rayons mous dorsaux (Total) : 56 - 70; Épines anales: 0; Rayons mous anaux: 50 - 59; Vertèbres: 46 - 49. First dorsal reduced to a single ray followed by a band of brush-like filaments; second dorsal with 55-69 soft rays; gill rakers rudimentary (Ref. 9003). Caudal fin rounded. Dark brownish grey to reddish brown, paler below, sometimes with yellowish tinge (Ref. 9003).

Inhabits rock pools and shallow coastal waters; secretive species (Ref. 30464). Feeds on small invertebrates and fish (Ref. 9003). Probably nocturnal (Ref. 9003).

Estimates based on models

Preferred temperature (Ref. 123201): 13.2 - 16.6, mean 14.5 °C (based on 77 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5001 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00479 (0.00208 - 0.01103), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 3.9 ±0.57 se; based on food items.

Résilience (Ref. 120179): Haut, temps minimum de doublement de population inférieur à 15 mois (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low vulnerability (20 of 100).

Catégorie de prix (Ref. 80766): Medium.
