I came across a couple invertebrates on the last dive to the oil rig Eureka (off Long Beach, CA) and I can't seem to find a source to ID them. Any pointers are greatly appreciated. Both were at about 50-70ft.

Also does anybody know of a good ID book for "jellies" in the widest sense? Either there are a lot more in the water this year or I am just taking more interest to them lately. Either way, they are pretty cool and I'd like to be able to ID them.

Thanks, Sergio

They're not jellyfish, they are pelagic tunicates. The first is a salp, maybe Salpa aspera. The second appears to be a colony of Pyrosoma atlanticum.

There is an excellent book: Pacific Coast Pelagic Invertebrates, by David Wrobel and Claudia Mills.

First one is the pteropod Corolla, not a salp. Nice pic showing the pseudoconch inside.


I second the recommendation of Wrobel and Mills, if you can find a copy...
