This species is distinguished by the following characters: A 18-20; scales in the transverse series 12-14 + 1 + 9-10; no scales from head, nape, belly, pectoral base and area immediately adjacent to bases of first dorsal and anal fins; maxilla reaching posteriorly to below pupil; eye diameter 7.4 -8.9% of SL; head length 29.2-32.4% of S.L.; first dorsal spine 7.8-8.7% of S.L.; and its colouration (Ref. 86997).

Inhabits large rockpools (4 m diameter) and among rocks covered in coralline algae at 2 m depth (Ref. 86997).

Estimates based on models

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

Bayesian length-weight: a=0.00562 (0.00258 - 0.01228), b=3.08 (2.89 - 3.27), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref. 93245).

Trofisk nivå (Ref. 69278): 3.0 ±0.3 se; based on size and trophs of closest relatives

Resiliens (Ref. 120179): Hög, lägsta populationsfördubblingstid mindre än 15 månader (Preliminary K or Fecundity.).

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