Épines dorsales (Total) : 0; Épines anales: 0.

Found on the continental shelf and littoral areas (Ref. 247).A sluggish and inactive species that buries itself in sand or mud (Ref. 247). Also found around rocks, heads of submarine canyons, and sometimes near kelp forests (Ref. 247). Feeds on bottom and epibenthic fishes, including croakers, California halibut, and squid (Ref. 247). Ovoviviparous (Ref. 50449). Can whip up its head and snap very quickly when touched, provoked, harassed, or speared, and can inflict painful lacerations (Ref. 247).

Estimates based on models

Preferred temperature (Ref. 123201): 12.5 - 25.9, mean 21 °C (based on 60 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5000 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00676 (0.00293 - 0.01558), b=3.07 (2.88 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).

Niveau trophique (Ref. 69278): 4.1 ±0.4 se; based on diet studies.

Résilience (Ref. 120179): Très faible, temps minimum de doublement de population supérieur à 14 ans (K=0.15-0.16; tm=8-13; tmax=35; Fec=6).

Fishing Vulnerability (Ref. 59153): High to very high vulnerability (67 of 100).

Catégorie de prix (Ref. 80766): Medium.

Nutrients (Ref. 124155): Calcium = 17.5 [3.6, 86.6] mg/100g; Iron = 0.795 [0.206, 2.275] mg/100g; Protein = 19.9 [17.8, 21.8] %; Omega3 = 0.363 [0.162, 0.801] g/100g; Selenium = 26.5 [7.5, 76.0] μg/100g; VitaminA = 9.99 [3.53, 27.74] μg/100g; Zinc = 0.421 [0.203, 0.760] mg/100g (wet weight);
