Cratena peregrina at lunch time
January 17, 2007
From: Dominique Horst
Dear Bill,
Back from my morning dive, I've realized on my PC screen, that I was lucky today to get a complete sequence of the lunch of a Cratena peregrina.
So I'm happy to share this on the forum. Having to select just 3 pictures was very hard.
Locality: Cap d'Antibes, 20m, France, Mediterranean sea, 07 January 2007, rocks. Length: 25mm. Photographer: Dominique Horst.
Kind regards,
Dominique

Dear Dominique,
This Cratena must have been down to the last polyp when you found it. I think you have made an excellent choice of photos. Since the skin of these animals is quite transparent you can often see internal structures. In this case I have put a ring around a curved tube which is the intestine, running from the stomach to the anus, which is obscured just behind one of the small cerata. Part of the duct is filled with an orange substance, which is the remains of the hydroids Cratena has been feeding on.
Best wishes,
Bill Rudman
