Mexichromis multituberculata from Egypt

Can you help me? I have some pictures of slugs. It´s from Red sea. I think that it is Mexichromis multituberculata or Mexichromis mariei. What do you think?

Dear Martina,
From the very large tubercles this can only be Mexichromis multituberculata, which makes your find a very large range extension from the Western Pacific.

One thing of special interest is that your photos could have been part of the same series of photos in Jun Imamoto's message [#14106 ] from Japan. In both cases, the animals are feeding on the same sponge, which Dr P.R. Bergquist has identified as a species of Euryspongia [F. Dysideidae]. This is a very valuable addition to our knowledge of the biology of this species.
Best wishes,
Bill Rudman
