I found this animal which was very like the photograph of Shinji Kitagawa message #12463.
Here is a photo of an animal I don't think is Pseudobornella orientalis, although I saw typical Pseudobornella orientalis at the same place.
Although Pseudobornella orientalis has branched dorsal papillae like shown of the Anatomical Information Page, this animal has only one a pair of these branched papillae and a single long unbranched papillae on the tail.
What do you think?
Date: 13 March 2004 at night diving

I think this is a damaged individual. The unbranched papilla on the tail is almost certainly a branched one that had lost its branches. You can see some bumps on it which may be the 'stumps' of the lost branches. Even though your animal is damaged, your close-up photos of the rhinophore stalks and the gill-like branches on the mantle cerata are a valuable addition to out knowledge of this strange animal.
