Dendronotus on oil rigs off California

February 9, 2005
From: Bruce Wight

I was out at the oil Rigs off San Pedro, California, for the first time in April 2004 and saw this Dendronotus I need help in identifying.

Take care,
Bruce Wight

Dear Bruce,
I am afraid your message is part of my large backlog but it deserves posting as the Dendronotus seems very interesting. I am pretty sure it is the animal Dave Behrens has as Dendronotus sp. 1 in his Pacific Coast Nudibranchs (Edition 2).

I have made a Fact Sheet for it as Dendronotus sp. 3
Best wishes,
Bill Rudman
