Comment: Re :strange jellyfish showing up in East Sooke.
The photo which was sent to you is not a jellyfish, but a floating pelagic snail which are not cnidarians (jellyfish, hydroids, corals ,sea anemones) but mollusks (octopus, snails, squids). Some of the marine snails develop their muscles into jelly, so that they can float like jelly fish, but this is their only similarity with jellyfish.They don’t have stinging cells.The one in the photo is called MELIBE LEONINA with its scientific name, hooded Nudibranch or lion Nudibranch, for its huge mouth and hood tentacles resembling a lion’s mane with its common name.
It is common in protected bays in August and September.
I found it for many years in “Jocks Dock”
