Lobiger souverbii

I'm trying to find out about the sea slug Lobiger souverbii. All I've been about to find out so far is that is covered in small bumps and can be found feeding on green weeds in shallow waters of the Papua New Guinea, Indonesia and the Solomon Islands.

Any info would be much appreciated!

Dear Rosemary,
I am not sure if your interest is in Lobiger souverbii or in the Lobiger that is found in the southwest Pacific.

Lobiger souverbii was described from the Caribbean and has been reported in the tropical and subtropical waters of the western Atlantic as far south as Brazil. Some authors have decided that the Atlantic species is the same as the Indo-West Pacific species Lobiger viridis, but that opinion is by no means unanimous. Certainly both species are similarly coloured and can have dark blue lines on the mantle but there have been differences reported in the anatomy which need checking. One other external difference I think needs checking is the shape of the four parapodial extensions. In animals from the Indo-West Pacific, which I am familiar with, the four primary lobes have secondary lobes along each side. These can be clearly seen in my photos on the Lobiger viridis page. I have never seen Caribbean animals alive, but from drawings and photos there don't seem to be secondary lobes, although there is some crenulation along each edge.

If anyone familiar with Caribbean animals could send some photos, or even a description, it would be very interesting.

If your interest Rosemary, is in the Pacific species then go to the Lobiger viridis page where I discuss some features of this animal.

Best wishes,
Bill Rudman.
