Dear Chay Hoon,
Thanks for this very interesting observation. When I looked at your photo before reading your message, my first thought was that the prey was Philinopsis lineolata being held at its posterior end. Did you have a look at the prey or did you decide not to disturb Gymnodoris while it was feeding? It would be nice if it was a chromodorid because it would suggest they target that family, but unless you have further information I cant be sure if it is Philinopsis or Chromodoris.

My plan this year is to finish a revision of the genus Gymnodoris which has been almost complete for about 5 years, so any other observations on feeding would be a valuable, and timely contribution.

Best wishes,
Bill Rudman
