East Pacific red octopus
''Octopus rubescens'' (Commonly the East Pacific red octopus, also known as the ruby octopus, a preferred common name due to the abundance of octopus species colloquially known as red octopus) is the most commonly occurring shallow-water octopus on much of the North American West Coast, and an ubiquitous benthic predator in these habitats.〔Onthank, K.L. (2008). . M. Sc. Walla Walla University, College Place, WA: 91〕 Its range extends from the southern Gulf of California at least to the Gulf of Alaska, but may also occur in the western Pacific Ocean. ''O. rubescens'' occurs intertidally to a depth of 300 m.〔Hochberg, F.G. (1997). ''Octopus rubescens''. Proceedings of the workshop on the fishery and market potential of octopus in California. Smithsonian Institution (Washington, DC).〕
==Taxonomy==
In the years prior to the description of this species in 1953, ''O. rubescens'' was widely considered to be a young ''Enteroctopus dofleini''. Many early descriptions were based on a combination of ''O. rubescens'' and ''E. dofleini''.〔〔Hochberg, F.G. (1998). ''Octopus rubescens''. In: P.V. Scott & J.A. Blake (Eds.) ''Taxonomic Atlas of the Benthic Fauna of the Santa Maria Basin and the Western Santa Barbara Channel: Vol. 8''. (pp. 213–218). Santa Barbara, California, Santa Barbara Museum of Natural History.〕 To date, the taxonomy of this species remains somewhat unresolved. S.S. Berry’s 1953 description is in truth a brief diagnosis,〔Berry, S.S. 1953. Preliminary diagnoses of six west American species of ''Octopus''. ''Leaflets in Malacology'' 1:51–58.〕 and considering the exceptionally wide range of the species, the animals currently covered under ''O. rubescens'' may prove to represent several subspecies or a species complex.
