In the pages linked below I’ve posted photos and a little text about the cnidarians and ctenophophores you might encounter in the exposed rocky intertidal or washed up on northern Oregon beaches. I’ve split my treatment into separate pages for sea anemones, jellyfishes, and ctenophores.

Identifying some of these species can be tough for a non-expert like me. Still, I can’t resist trying to put a name on all species I encounter. My pages keep getting new additions because the more I learn, the more I see. All this effort at naming isn’t mere collecting or listing. Learning to identify helps me understand and communicate connections. And that’s fun. I make no promises that the IDs I propose are correct. If you see a mistake or an out-of-date usage, I hope you’ll let me know.
