Mjukstrålar i ryggfenan (totalt) : 76 - 85; Mjukstrålar i analfenan: 51 - 58; Ryggkotor: 44 - 46. The species is characterized by the following: vertebrae 13-14 + 30-32 = 44-46, dorsal fin rays 76-85, anal fin rays 51-58; body with scales; posterior infraorbital pores 3; ventral spine on maxilla positioned behind rear of eye; single pair of pseudoclaspers straight, spiny, short, about half the length of penis, without fleshy appendices; otolith with rounded posterior tip and weak postdorsal angle, otolith length to height ratio 2.0, sulcus with nearly fused colliculi (Ref. 57886).

Occurs on rocky shores down to 17 m, most commonly deeper than 5 m (Ref. 57886).

Estimates based on models

Phylogenetic diversity index (Ref. 82804): PD₅₀ = 0.5312 [Uniqueness, from 0.5 = low to 2.0 = high].

Bayesian length-weight: a=0.00389 (0.00180 - 0.00842), b=3.12 (2.94 - 3.30), in cm total length, based on all LWR estimates for this body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.3 ±0.5 se; based on size and trophs of closest relatives

Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
