One of a number of tritoniids described by Ruppell & Leuckart from the Red Sea. Jochen Scholtyssek's photo matches the original illustration quite well. At this stage we do not know if the many available names for these soft-coral feeding tritoniids represent good species or colour variations.

Thanks for this. It's always good to get another piece to fit in the puzzle. The animal in this photo could have been the one used in the painting of Tritonia rubra in Ruppell & Leuckart (1831), so I have no doubts in identifying it as Marionia rubra. One feature characterising this species are the many bushy gills down each side of the body

Here are some Video-Pictures of a new seaslug. It is 4cm long.
Is the name Marionia rubra ?

Yes I think this is Marionia rubra. This group of tritoniids needs more work. At the moment it is hard to say how many species there are in the tropical Indo-West Pacific. It is possible that species vary in colour depending on the colour of the soft-corals they are feeding on but basically we don't know.
