Working on Okenia zoobotryon

April 9, 1998
From: Alana Synhoff

I am a graduate student at UCF and I am working on Okenia zoobotryon, a small dorid nudibranch found in the Indian River Lagoon (east coast of Florida near Daytona Bch, FL). Okenia zoobotryon feeds upon the bryozoan Zoobotryon verticillatum which produces a bromo-alkaloid, 2,5,6-tribromo-methylgramine which has shown to act as an antifouling substance in barnacle cyprids.

Any info on this topic would be appreciated. It appears that not much is known about O. zobotryon, and just a little more is known about Z. verticillatum. I need info on any other bromo-alkaloid relationships between slugs and their prey (even if they are not dorids). Any chemistry relationships in general would also be useful to my research.
Thanks!

If you could send me a photo of Okenia zoobotryon it would be interesting to put it on the site. I have often wondered what this apparently common little species looks like. The drawings which have been published are either of preserved animals or not that informative. Your Okenia seems to be just the sort of species which could become a world traveller, so it would be useful if we could keep an eye out for it. I suspect your bryozoan, Zoobotryon, is found here. Concerning your more specific enquiry about bromo-alkaloids, perhaps Tony Wright (a.wright@tu-bs.de), who sent a question on Reticulidia halgerda could help you
