Concerning message #7648:

Dear Bill
I send you here some more pictures of Thecacera sp. 2.
One specimen was really tiny, about 7 mm, probably a juvenile! The large one you see eating a bryozoan.

I have also seen other Thecacera species such as Thecacera picta eating bryozoans (I have sent you a picture separately [#21602 ]). I guess this is their staple food.

Locality: Komodo (small nudi) and Sulawesi, 15-20 m, Indonesia, Pacific, July 2005, sand and rubble with little coral cover. Length: 7 mm (small) and 2 cm. Photographer: Teresa (Zubi) Zuberbühler.

Dear Zubi,

Thanks for these photos. Apart from the feeding record they show the strange ribbed 'plate' at the base of the rhinophore stalk very well. As I have mentioned before it looks a though it could be a sensory structure

Best wishes,
Bill Rudman
