I think Halgerda dalanghita on your site and this animal are similar. They were feeding on the yellow sponge I have photographd them on.
I hope you can recognize that there are two animals in the lower left image.

Thnaks for these photos which give us a bit more information on the species. I have included an enlargement (lower right) of the second animal in your photo so we can see it more clearly.
