Good to see the Forum up and running again!
I want to expand the list of sacoglossans, and add here Elysia thompsoni Jensen, 1993, (many thanks to Kathe Jensen helping me identifying it). The specimen in the picture was collected at Rat Island, Houtman Abrolhos, Wstern Australia, July 21st this summer. We found at least a good 20 individuals around the jetty at 2-4 meters depth under dead coral blocks. Later we also found this species (two specimens) in Shark Bay at Eagle Bluff near Denham just near the shore at 1.5 meters depth.
It also showed active photoynthesis, and these results will hopefully be published in the Records of the Western Australian Museum soon.

It's good to get another sacoglossan to add to the Forum, especially a solar-powered one. I look forward to reading more about it in your publication. It would be interesting to know if it feeds on Acetabularia, as it has many similarities to Elysia timida.
