Feeding habits of Roboastra

April 30, 1999
From: Juan Lucas Cervera

Hi Bill!

I have readed the different messages and replays about the subject 'Tambja affinis v. Roboastra luteolineata' recently. I'm absolutely in agreement with you respect to the identification of nudibranchs in many of beautiful books of photographers. Some people send me slides of opisthobranchs for their identification, and many times I reply that I would need the specimen/s to examine the internal anatomy.

I'm very interested to receive all the known information about the feeding of Roboastra, that is poor except for Roboastra tigris. I am finishing a paper about the feeding habits of the European species Roboastra europaea. I have examined the digestive contents of more than 30 specimens, moreover to have carried out field and laboratory experiences in which specimens of Roboastra europaea meet different species of the same or different families of nudibranchs.

I think it would be very interesting to compare our results with those of other species of Roboastra.

Regards.

Juan Lucas Cervera.

Dear Lucas,
I'm afraid I have no feeding records of Roboastra in Australia and New Zealand. I hope some of our New Zealand friends have made a mental note to look for and photograph them in the act! One of my aims with the Forum is to provide a place where people can report such finds and publish photos for everyone's benefit.

Your work on Roboastra europaea sounds fascinating. Any chance of a photo for the Forum? I planned to restrict the Forum to Australia and New Zealand, but it didn't take long to realize its definitely World Wide, so I am happy to receive photos of any of your interesting and equally beautiful animals.

Best wishes,
Bill Rudman.
