Trapania lineata from Antibes, France

August 10, 2006
From: Dominique Horst

Dear Bill,
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,
Kind regards,
Dominique

Dear Dominique,

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].

Best wishes,
Bill Rudman
