Oxynoe viridis life cycle

May 31, 2002
From: Amanda Edwards

Hi Dr Rudman,
My name is Amanda Edwards and I am currently doing an Honours project at Wollongong University with Andy Davis and Jeff Wright. My project involves looking at fauna associated with a number of Caulerpa species. It also involves a set of feeding trials on Caulerpa taxifolia and C. filiformis with Oxynoe viridis . At the moment I have not been able to obtain much useful information on the Oxynoe viridis life cycle or how to raise and culture them in a lab. Could you please give me an idea of how to do this and the names of some web sites or books that could help me? Also, do you know what species of opisthobranchs are associated with different Caulerpa species. Your help would be much appreciated.
Thanks heaps!

Dear Amanda,
Your project sounds very interesting and I look forward to hearing of your results. I don't know of any life history / life cycle studies on Oxynoe viridis but I am pretty sure it has planktotrophic eggs so will be difficult to breed in aquarium conditions unless you have facilities to culture phytoplankton-feeding veliger larvae. Concerning feeding, have a look at the Sacoglossan Feeding and Sacoglossan Biology pages for some background information. There are references and messages there discussing the food of Australian species.

There is also a lot of information on feeding scattered through various messages so it would pay to use the search facility on the Forum to search for food and feeding. Another way would be to look through the sacoglossan species in the Species List. There are many photos of species on their probable food algae.
Best wishes,
Bill Rudman
