Solar-powered sacoglossans in Norway?

March 9, 1999
From: Jussi Evertsen

Dear Bill.
Thank you very much for your help. I am also very curious about if any of the Elysia species found here in Norwegian waters might show "solar power" affinities. Do you have any clue to which longtitude this solar power affinities work? Is this simply a tropical trait?

Your sincerely

Dear Jussi,

There are sacoglossans in quite northern latitudes with symbiotic chloroplasts. For example Elysia chlorotica in Nova Scotia and Elysia viridis in England. Also the photosynthetic flatworm Convoluta roscoffensis lives in the North Atlantic.

I have posted a list of publications on chloroplast symbiosis which may be useful. Any updates would be welcome.

One active research worker in the field, who could give you up to date advice is Cynthia Trowbridge whose address is:

Best wishes,
Bill Rudman.
