Biology     Glossary (e.g. epibenthic)

Facultative air-breathing (Ref. 126274); 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 based on models

Preferred temperature (Ref. 123201): 9.3 - 18.2, mean 10.8 °C (based on 158 cells).
Phylogenetic diversity index (Ref. 82804):  PD50 = 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.).
Fishing Vulnerability (Ref. 59153):  Low vulnerability (13 of 100).
