Dear Dr Bill,
here's another photo of Gymnodoris rubropapulosa caught in acton of feeding during my recent dive at Pulau Hantu.
I would love to see if it can really finish the bigger prey but unfortunately I was running low on air.
Locality: Pulau Hantu, 7m, Singapore, South China Sea, 20 December 2008, Silty substrate. Length: 25 mm. Photographer: Toh Chay Hoon.

It certainly seems that the hunting response in some of these 'hunting' nudibranchs (Gymnodoris, Roboastra ) is triggered by 'taste' or 'smell' and size is not taken into consideration. We tell children who take to much food that there 'eyes are bigger than their stomachs' but I guess since the eyes of these nudibranchs can't actually see images they can't judge when their target is inappropriately large.
Best wishes,
Bill Rudman
