Hypselodoris picta from near Cannes, France

June 9, 2006
From: Dominique Horst


Hello,

I've identified these specimen as Hypselodoris picta. I guess you will confirm. But previously, I got in the literature two different names H. webbi and H. elegans that I could not find in the species list. Are they names for other animals or are they synonyms for the same one ?

Locality: Iles de Lérins, nr Cannes, France, Mediterranean sea, 25 November 2004, vertical rock. Length: 100mm. Photographer: Dominique Horst.

(Colours of the the gills are yellow-blue for one and blue-yellow for the other one on the same picture.)

Kind regards,
Dominique

Dear Dominique,
Yes these are H. picta. Because biologists have had a  lot of trouble sorting out just how many species of Atlantic 'blue chromodorids' there are, the names and their usage has been quite confused - and still remains so in some cases. So it is not surprising that some books still misidentify species or use the wrong names.

Both H. webbi and H. elegans are synonyms of H. picta. Concerning the colour of the gills in your aniamls. I think the difference is just in the intensity of the blue. One animal has quite a deep blue background colour while the in other the blue pigment is almost absent.

Concerning your being unable to find H. webbi and H. elegans in the species list. The Forum species list only includes species at present on the Forum, it is not a list of all opisthobranch names. I often include major synonyms on the Fact Sheets, so if you are looking for a particular name, which may be a synonym, it often pays to use the general Forum Search facility at the top left of each page. If you do, just use the species part of the name - 'webbi' - not 'Hypselodoris webbi'.

Best wishes,
Bill Rudman
