Concerning message #16583:
Dear Bill,
I found yesterday three specimens of Umbraculum umbraculum, with Philibert Bidgrain (Reunion Seaslug site). The first one [lower right photo] was the biggest we have ever seen (180 mm), and the others were relatively standard(140 mm). We can see the mouth in middle left photo. It seems a good season to find them.
Locality: Etang-Salé, Côte Rocheuse, 0,5 metre, Reunion Island, Indian Ocean, 28 November 2006. Length: 180 mm and 140 mm. Photographer: Hugues Flodrops.
Regards.
Hugues

Thanks Hugues,
I guess the sizes you give are shell lengths? It is interesting how your animals seem to be without any growths on the shells, while in some parts of the world the shell is always covered in algae and colonial animals. Thanks for the photo of the mouth [middle left photo]. I have added a close-up [middle right] to show the front of the body. You would expect the mouth to be up near the eyes and head tentacles [rhinophores] which can be clearly seen at the top of the body, but in this strange animal the mouth is far away on the sole of the foot. Running down the front of the body, from the eyes to the mouth, is a deep vertical groove, which contains the openings of the reproductive system
Best wishes,
Bill Rudman
