Hypselodoris picta from the Adriatic Sea
July 1, 2001
From: Buga Berkovic
Hi!
I have found something which looks very much like the photos on the Forum of Hypselodoris picta & the slug from Florida only it's more green, in fact it is dark green with lot of yellow dots that sometimes form lines. There were six of them together, about 3 meters deep and not more than 15 meters from the coast. Bottom was mostly sand, some rocks, covered with vegetation.
My problem is this: I can't find any literature on it, or whether anything like it has been found in the Adriatic sea, where I've found them. So the most important thing I wish to ask you is if you know do they live here, and if yes - which species.
I'm just an amateur-diver (not yet SCUBA, but soon) so unfortunately I don't have an underwater camera, but I took these animals out and put them in a bucket full of water and took the pictures. I was watching them for 5 days - every day I found them somewhere near the location where I found them the first day. I have total of allmost 35 photos! If needed, I also have a picture of a baby, about 0.6 cm long!
Animals range in length from about 5 cm to around 17 cm when fully stretched (see on the picture!). I found them in south Adriatic near Dubrovnik area (island of Korcula). I hope you can tell me what are they, because I have started to be very interested in them, and I'm even going to try to study marine biology in Vienna so I could professionaly work on them in future! If any more details are needed just say and I'll try to give them to You!
Thanks a lot!

Dear Buga,
I am pretty sure your animal is Hypselodoris picta, which is quite variable in colour. However there are quite a few similarly coloured species in the Mediterranean and nearby waters so I think we should wait for confirmation from one of the European workers more familiar with the local fauna. Do all the animals you have found have spots, like in the photos, or do some have lines instead? If there are lined specimens a photo of one of these would be interesting.
We know very little about the basic natural history of these animals so if you were able to find what sponge it was feeding on, and perhaps photograph it, and photograph its egg ribbon, that would be useful. I realise that this may all be impossible, when you are limited to photographing in a bucket, but I am always optimistic.
Best wishes,
Bill Rudman
