Concerning message #3768:
I've identified this as Trapania pallida. It is the first time I have seen it. It apparently feeds on Cnidarian (Leptogorgia sarmentosa).
Except a friend of mine in mid January I've never read or see anything about this species in Mediterranean...

This certainly looks like T. pallida to me and I can't find any record of it from the Mediterranean so you may have documented an interesting range extension.
Concerning its food. Bernard Picton's message [#3767] was one of the first that clealry showed that species of Trapania feed on entoprocts [Kamptozoa]. Negatives are hard to prove, but I would be surprised if T. pallida fed on a cnidarian - it is certainly not a normal food of any dorid species.
