Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 6.4 cm TL male/unsexed; (Ref. 2850)
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).
