Tethys fimbria from Croatia

Concerning message #21580:

Dear Bill,

Here is a picture I took last week in Croatia, of a Tethys fimbria. From the distance I first thought it was a plastic bag because of the size, since I never had the opportunity before to see a slug of that size. As you can see the oral hood is not in the position (attached to the ground) as shown on the other pictures here. Unfortunately I don't know why.

Locality: Trogir, 43 m, Croatia, Mediterranean, 22 August 2008. Length: 35 cm. Photographer: Matthias Mauser.

Last but not least, I want to congratulate to this very interesting website.

Best Regards from Vienna
Matthias

Dear Matthias,

The oral hood is not always attached like a disc to the ground. The edge of the hood - with the sensory papillae - is very flexible and it moves around often not in a nice circle, feeling for small crustacea in the sand or mud. In your photo it seems to be interested in something on the right side of its head so the hood has moved over that way to feel around.

Best wishes,
Bill Rudman
