Elysia ornata? from Bali
July 13, 2006
From: Kevin Lee
Hi Doc,
Just parachuted back home (California) after doing some dives in Bali and Lombok, Indonesia. Didn't see as many sea slugs as hoped, but would appreciate ID assistance for the ones I did.
The following 3 fotos are separate slugs, but am assuming the same species. It was the only slug, and plentiful, I saw during 2 dives, at Secret Bay, Bali, Indonesia. The largest slug, seemed to have only "nubs" for rhinophores; perhaps they were nibbled away by predators or...?
Locality: Secret Bay, Gilimanuk Town, Between 7 and 15 feet, Bali, Indoneisa, Java Sea, 12 June 2006, Muck dive, mostly muddy sand. Length: approx. 1 inch; 1.5 inches; 2 inches [upper to lower photos]. Photographer: Kevin Lee.
Best regards,
K:-)

This is a good example of why there seems no easy soluttion to whether Elysia ornata and E. grandifolia are one or two or perhaps even more species. You'll notice that both the upper animals have a distinctive yellow submarginal border on the parapodia but it is absent in the larger lower animal. But in that animal the black spots are more numerous. The intensity of the green colour is unimportant because it reflects the amount of green algal material in the digestive system rather than genetic differences.
At present I am putting most of the elysiids with this colour pattern under E. ornata, but I suspect there will have to be some splitting when this group is studied in detail. I agree that the shortness of the rhinophores in the lower animal is most probably the result of interaction with a predator.
Best wishes,
Bill Rudman
