Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 0; Spine anali: 0. Head depressed. First dorsal fin poorly developed, with only three short rays. Color uniformly dark brown or bluish brown; the lips and the distal areas of all fins paler except for the pectorals.

Lives in coastal waters at shallow depths, generally from 10-20 m, more seldom from 75-100 m, on rocky bottom with seaweeds. Solitary and secretive, undertakes only limited local movements. Spawns from May to September at 50-70 m depth near the shore throughout its entire range. Feeds on sea stars, crustaceans, worms, mollusks and small fish (Ref. 1371).

Estimates based on models

Preferred temperature (Ref. 115969): 8.5 - 12.5, mean 10.4 (based on 120 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 1.0000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.01072 (0.00412 - 0.02789), b=3.06 (2.83 - 3.29), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.56 se; based on food items.

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