Morphology | Morphometrics
Intertidal (Ref. 31184), commonly found in rockweed (Fucus) masses, in tide pools and inshore areas. May remain out of water under rocks or seaweed (Ref. 31184). Feeds on small crustaceans and mollusks. Breathes air (Ref. 31184) and can stay out of water for 5-20 hours if kept moist (Ref. 51276).

Phylogenetic diversity index (Ref. 82805
= 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00102 (0.00046 - 0.00225), b=3.06 (2.88 - 3.24), in cm total length, based on all LWR estimates for this body shape (Ref. 93245
Trophic level (Ref. 69278
): 3.4 ±0.4 se; based on diet studies.
Resilience (Ref. 120179
): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref. 59153
): Low vulnerability (25 of 100) .
