Cnidarians & the Like

In the pages below I’ve posted photos and a few words about the common cnidarians and ctenophophores you might find in the rocky intertidal or washed up on northern Oregon beaches. These pages aren’t by any means complete treatments, they just show examples of anemones, hydroids, jellies, and ctenophores I’ve been lucky enough to come across.
