Feeding record - Trapania lineata from Antibes, France

Concerning message #17030:
Dear Bill,
When I saw three Trapania lineata, I was surprised about their black colour. Usually they are transparent or light yellow... After looking at the picture, I've realized it's because they were eating the small black animals and this reminded me of your reply to my previous message about Trapania lineata [#17030 ].
I guess you will confirm, that these Trapania were feasting and stuffing themselves with Entoprocts.

Kind regards,

Dear Dominique,
Thanks for this nice observation of its feeding behaviour and of how they can change colour. When you are transparent like this, its a bit hard to hide what you have been eating.
By coincidence, Lucas Cervera has kindly sent me a copy of a paper of work that Luis Sanchez Tocino and he have published on the diet of Trapania maculata and T. hispalensis. They report that both species feed on a kamptozoan [= entoproct] of the genus Loxosomella, which is a nice addition to David Abecasis's photos of T. hispalensis [#14717] apparently feeding on kamptozoans.

Best wishes,
