Distribution Countries | FAO areas | Ecosystems | Occurrences | Point map | Introductions | Faunafri

Eastern Pacific: Trail Island, Wark Channel, northern British Columbia to Bahia Santa Maria, southern Baja California, Mexico. Probably occurring in southeastern Alaska (Ref. 2850).

Biology     Glossary (e.g. epibenthic)

Commonly found on sand bottom, also on mud bottom. Occurs in intertidal areas and up to 142 m depth (Ref. 2850). Feeds on shrimps and other crustaceans (Ref. 4925). Aquarium observations indicate that this is nocturnal (Ref. 2850).

Estimates of some properties based on empirical models

Phylogenetic diversity index (Ref. 82805):  PD50 = 1.0000   [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=-2.41000 (nan - nan), b=3.12 (2.94 - 3.30), based on all LWR estimates for this BS (Ref. 93245).
Trophic Level (Ref. 69278):  3.6   ±0.55 se; Based on food items.
Resilience (Ref. 69278):  Medium, minimum population doubling time 1.4 - 4.4 years (Fec=5,700).
Vulnerability (Ref. 59153):  Moderate vulnerability (38 of 100) .
Price category (Ref. 80766):   Low.
