There are just a couple of kinds of octopuses in the tidepools. In addition, several species of squids occasionally wash ashore, and it’s not uncommon to find squid eggs among the sea wrack.
I think this little octopus has characteristics in line with Octopus rubescens, but I have almost no experience with octopuses, so I’m not making the call. However, I’d appreciate it if you’d drop me a line if you can identify this cutie.
