Dorsale stekels (totaal) : 8 - 10; Dorsale zachte stralen (totaal) : 16 - 19; Anale stekels: 0; Anale zachte stralen: 13 - 15. Caudal fin barely rounded.
Intertidal (Ref. 31184). Occurs in rocky areas and in kelp beds (Ref. 2850). Usually caught from lower tide pools (farthest from shore) (Ref. 2850). Can leave tide pools when aquatic conditions become inhospitable (Ref. 31184). Breathes air when out of water (Ref. 31184).

Estimates based on models
Preferred temperature (Ref.
123201): 8.5 - 17.1, mean 10.1 °C (based on 205 cells).
Fylogenetische diversiteitsindex (Ref.
82804): PD
50 = 0.5625 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00676 (0.00300 - 0.01523), b=3.17 (2.98 - 3.36), in cm total length, based on LWR estimates for this (Sub)family-body shape (Ref.

Trofisch niveau (Ref.
69278): 3.1 ±0.3 se; based on size and trophs of closest relatives
Weerstandsvermogen (Ref.
