Unnamed Dendronotus

Dave Behrens reports that this is possible a weird white Dendronotus frondosus, or it could be a new species.

Information from Dr. Hans Bertsch on Nudibranch specimen collection. Note - this should only be used for research or identifying new species that cannot be identified from photographs. No need to kill anything without a good reason.

1. Use a large clean plastic jar to put them in. Don't squeeze or injure them during collection.
2. It's OK to put 3 or 4 per jar. Fill the jar with water and freeze it.
3. Keep notes on location (lat & long if possible), depth, size alive, who collected, etc.
4. Write the note in pencil on a piece of index card and add it to the frozen jar.
5. Keep the jar frozen until you can get it to the experts.

Nudibranch Eggs

This a beautiful nudi egg cluster. Several large Diaulula nobilis were noted in the area.

Unnamed Dendronotus with eggs.
Ship Rock, Catalina Island, CA

Nudibrach eggs are near the chain. Hermissenda Crassicornis in the upper left.

This is a collection of the nudibranch pictures from my other pages. I try to put the best example of each species on this page to help me keep track of which ones I've photographed. I'm a neophyte slug hunter so If you see any errors in my nudibranch identification please send me an email.

"PCN pXX" is my shorthand for the page number of "Pacific Coast Nudibranchs, Second Edition" by David W. Behrens. This book is a great resource for SoCal Nudibranch ID.
