The identification is based on what others suggested the last time I saw at octopus as this location.
Part of the same hatch as the previous observation.
I can't tell if that dark spot is the "eye" marking on O. bimaculoides or not.
The East Pacific red octopus (Octopus rubescens) is the most commonly occurring shallow-water octopus on much of the North American West Coast, and a ubiquitous benthic predator in these habitats. 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.
