The ones below were found at Schmitz Park beach in West Seattle. One had limpets on the outside of the shell and narrow grooves on the inside. A few others had worm tubes attached to the shells that left marks where removed but not real grooves. So we are no nearer to the answer to the mystery except that our octopus expert does not see this as the work of an octopus...so I'm dropping that suspect.
Just to keep things interesting a jellyfish showed up with what appears to be 10 lobes....red in color and only palm size. Will need some work on the keys to figure this species out as our common Fried-egg Jellyfish has 16 lobes and the Red Sea Blubber has 8.
Opalescent Sea Slugs are showing up on Moon Snail sand collars along with their eggs.....as well as the green eggs of the green polychaete worm Phyllodoce williamsi.
