Another slug on my way today. It should be Trapania lineata. It was feeding the sponge Reniera fulva may be? Would you have any information about their food ? Could it be this sponge ?
Locality: Cap d'Antibes, 13m, France, Mediterranean sea, 29 June 2006, vertical rock. Length: 3mm. Photographer: Dominique Horst.
It is so small that I've found it by chance. If this sponge is possibly their food, then I will watch them with more attention.
Many thanks in advance,

Thanks for the photos. We thought for a long time that species of Trapania fed on the sponges they were so often associated with, but thanks to a lot of input from Forum participants, we now know better.
They feed on small stalked animals called Entoprocts [or Kamptozoa] which seem to live in association with some sponges. See good photos of this can be seen in Bernard Picton's earlier message [#3767].
