Short description Identification keys | Morphology | Morphometrics

Dorsal spines (total): 13; Dorsal soft rays (total): 8 - 9; Anal spines: 3; Anal soft rays: 5. Reddish in color (Ref. 4313). Confused with Helicolenus dactylopterus, but easily distinguished by shape of caudal fin and pectoral fin and number of rays in dorsal fin (Ref. 36731).

Found on the continental shelf and continental slope (Ref. 75154).

Estimates based on models

Preferred temperature (Ref. 123201): 2 - 9, mean 6.7 °C (based on 139 cells).

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5156 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00912 (0.00410 - 0.02027), b=3.09 (2.89 - 3.29), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trophic level (Ref. 69278): 3.5 ±0.50 se; based on food items.

Resilience (Ref. 120179): Low, minimum population doubling time 4.5 - 14 years (Preliminary K or Fecundity.).

Fishing Vulnerability (Ref. 59153): Low to moderate vulnerability (33 of 100).
