Short description Chiavi di identificazione | Morfologia | Morfometria

Spine dorsali (totale) : 9 - 10; Raggi dorsali molli (totale) : 17 - 18; Raggi anali molli: 16 - 18. Head large, without deep occipital groove. First dorsal spine serrate anteriorly, second spine not elongate. Lateral line scales plate-like expanded vertically. Breast and anterior part of belly without scales. Vertebrae 36-37 (13-14 precaudal and 22-23 caudal). Pectoral fin with last 3 rays free. Snout steep, prolonged forward by a denticulated and bilobed flattened rostrum.

Occasionally forms schools. Found over sand and gravel, crag, and rocks in the continental shelf (Ref. 2723). Feeds on benthic crustaceans, other invertebrates and bottom-dwelling fishes (Ref.4697).

Estimates based on models

Preferred temperature (Ref. 115969): 7 - 15.8, mean 10.1 (based on 667 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5010 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00794 (0.00661 - 0.00955), b=3.05 (3.00 - 3.10), in cm Total Length, based on LWR estimates for this species (Ref. 93245).

Trophic level (Ref. 69278): 3.8 ±0.1 se; based on diet studies.

Resilienza (Ref. 120179): Medio, tempo minimo di raddoppiamento della popolazione 1.4 - 4.4 anni (K=0.3; tm=2).

Prior r = 0.98, 95% CL = 0.64 - 1.46, Based on 1 data-limited stock assessment.

Fishing Vulnerability (Ref. 59153): Moderate to high vulnerability (46 of 100).

Price category (Ref. 80766): Very high.
