Lobiger from Gulf of Mexico

September 20, 2002
From: Anna L. Bass

Hello Dr. Rudman,
This interesting animal tricked me. I thought it was a random piece of algae stuck in the corner of the tank. I was quite happy to see that it wasn't just algae. I believe it came in on Caulerpa racemosa, but am not positive. It is 1cm in length. Is it Lobiger viridis?
Regards,
Anna

Dear Anna,
Thanks for these photos of the Caribbean Lobiger. As you will see amongst the messages on the Lobiger viridis page there is considerable confusion as to whether there is one circumtropical species or a separate Caribbean species. Until that is resolved I guess it is better to err on the side of conservatism and call the Caribbean species Lobiger souverbii. As it is the older name any way, that is what they all should be called if there turns out to be one species. One distinction I wondered about was that the Indo-West Pacific animals had secondary rolled flaps on their parapoda while the Caribbean animals just had a crenulated edge. Certainly your photos don't show the rolled secondary flaps but I don't know whether the difference is a constant feature in either the Caribbean or the IWP.
Best wishes,
Bill Rudman.
