Specifically, a couple of lines from "Here Comes The Flood":
Stranded starfish have no place to hide
Still waiting for the swollen Easter tide.
In this case, our strand-ee happens to be a jellyfish of unknown type (the Moon Jelly being the most common found in California waters, but the coloration doesn't seem to match.)
Note: photos were taken at extreme low tide. The next high tide will be come up past this point, hopefully providing safe passage back to the ocean.
