Hi Bill!

Thanks for your reply. I really have not detected your mistake spelling Roboastra.

I have no photographs about the feeding of Roboastra europaea, but a video movie of some laboratory experiences in which it can be seen several attacks on some nudibranchs. It also can be seen that it doesn't attack other nudibranch species that were offered. The scenes of the attacks are really impressive! Most of the victims cannot escape from the Roboastra at the first (and single) attack.

A question very interesting to study is if one species of Roboastra with a wide geographical range has always a preference to some preys or these can change depending of the geographical area.
