Pacific Sea Gooseberry, Pleurobrachia bachei

There are only a few “gooseberry” jellies in the Pacific Northwest and this is perhaps the most common.  It’s more globe-like, circular form initially differentiates it from the two other less common oval-shaped ctenophores, the Euplokamis dunlapae and the undescribed Cydippida  (For more information on plylum Ctenophore,  UC Berkeley’s Museum of Paleontology offers a quick and easily understood introduction).
