located on shell bottom 38 feet. It was probably clearing the area under the rock because the rock was moving up and down. It came out a bit.
Very large one, but I think not a Giant Pacific (alas).
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.
