The jellyfish was at Rosario Beach in Deception Pass State Park
The moon snail was in a touching pool at the PTMSC. It's about ten inches long. These snails eat clams and cruise through the sand with only the top of the shell visible. When they find a clam they wrap themselves around it and drill a hole in the clam's shell to get at the goodies inside. All you gardeners should be thankful that these are not a terrestrial species.
Most keyhole limpets have a commensal worm living inside the shell. This photo shows the worm which is about as long as the limpet.
The sunflower star was also at the PTMSC. By seastar standards these guys are fast - maybe four or five meters per hour.
