Dear Bill,
I think you are right in thinking our Dendronotus is not Dendronotus dalli. Thanks, I will update my slide index. Do you think it could be a Dendronotus albus for we saw many of them on the trip? Do they have the indicative white line also?

Concerning your question about eggs - No, those are not eggs in the background, they are the club-tipped tentacles of the sea anemone Corynactis californica.

Dear Bruce,
Now that you tell me, I can see the orange trunk of the sea anemone in the photo.

Concerning the identification of the Dendronotus, I hesitate to comment on the Californian fauna when there are so many others better qualified to do so. My understanding is that D. albus also has the opaque white line on the 'tail' but it usually has more than four pairs of cerata (usually 5-7), and usually has the cerata tipped with orange-yellow, although in rare cases this colour is absent. D. diversicolor has a white form that looks like your photo but I would rather a local expert confirms its identity for us.

A photo of 'typical' D. albus would be a nice addition to the Forum if you have any.
Cheers,
Bill Rudman
