Short description
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).

Estimates of some properties based on models
Phylogenetic diversity index (Ref.
82805): PD
50 = 0.7500 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.00178 (0.00072 - 0.00441), b=3.15 (2.93 - 3.37), in cm Total Length, based on LWR estimates for this (Sub)family-body shape (Ref.
93245).
Trophic Level (Ref.
69278): 3.4 ±0.4 se; Based on diet studies.
Resilience (Ref.
69278): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Vulnerability (Ref.
59153): Low vulnerability (25 of 100) .
