Chemical Defences in nudibranchs
April 30, 2000
From: Victor Bonito
Dear Bill,
I am interested in learning more about the aposematic colouration of flatworms and nudibranchs. While a lot of books refer to nudibranchs as being aposematic and sequestering chemicals from their food sources, I can not find any literature to support this. In the cases of flat worms mimicking nudibranchs, is there literature to support the fact that the nudibranchs
are in fact chemically defended (other than L. Newman's work with flatworms)? I am especially interested in Phyllidids, and any feeding assays that have been done with chemicals extracted from them.
Thank for your direction in finding some publications in this area.
Sincerely,
Victor Bonito

Bonito, V., 2000 (Apr 30) Chemical Defences in nudibranchs. [Message in] Sea Slug Forum. Australian Museum, Sydney. Available from http://www.seaslugforum.net/find/2336Dear Victor,
There is certainly a lot of published evidence to show that some groups of nudibranchs retain chemicals, from their food, for their own defence.
I have compiled a page of •references to chemicals in Phyllidiidae for you. It also includes two references to two major reviews which have excellent bibliographies.
If you use the SEARCH button you will find a lot of references to defence and mimicry in the Forum. In particular have a look at the pages on:
•Opisthobranch defence mechanisms
•Mimicry
•Defensive mantle glands.
There are references associated with those pages as well. Also look at the messages on each page because they also contain comments and references which may be worth following up.
Best wishes,
Bill Rudman.
