More photos of Elysia trilobata

Hi Bill,
Not the best photos, but this was quite small. We encountered what looks like an Elysiid sp. in a grassy area that often fruitful for 'branching.
Do you have any idea what this is?

Locality: Eilat, Tables South, Israel. Red Sea (Gulf of Eilat). Depth: 28 m. Length: approx. 1 cm. 16 February 2005. grassy expanse (with occasional small corals) at foot of slope. Photographer: Binyamin and Shulamit Koretz

Thanks again and regards

Dear Binyamin,
As I mention in your accompanying message [#13299], I couldn't identify these as Elysia trilobata from the photos alone because they don't show the typical 'trilobate' shape in this pose. The interesting thing about these photos is that in this contracted pose, the white pigmentation on the lobes is all that can be seen, and may help camouflage the animal in a coral rubble and coral sand locality. In these photo the animal appears to be on a green alga with a distinctive structure like some species of Microdictyon or Boodlea have. Perhaps there is enough structure visible for someone to suggest a possible food plant for this species.
Best wishes,
Bill Rudman
