Concerning message #12845:

Dear Bill,

We found this black Thecacera in Puerto Galera, which looks like Thecacera sp. 3. About 1 meter from it were two 2 gray/white animals.
The black one here has several small additional appendages, abnormalities?

Locality: Puerto Galera, 15 m, Philippines, 10 February 2008, sandy bottom. Length: 1 cm. Photographer: Marcel Tanke

Best regards,
Marcel

Dear Marcel,

Thanks for these photos. They solve the mystery of Thecacera sp. 3, as I am sure your greyish animals link the blackish one to the white Thecacera picta. Certainly the greyish ones are T. picta.

Concerning  'abnormal' appendages:  the small orange-tipped papillae at the base of the large appendages by the gills are unusual, but the ones up near the rhinophores are sometimes found in T. picta.  I am not sure about the large flap on the inside of the right rhinophore. It is possibly the sheath that usually surrounds the rhinophore club in this species. If it is, it is possibly misplaced through some damage or abnormality.

Best wishes,
Bill Rudman
