I think this is Hypselodoris lapislazuli found diving around the Galapagos Islands. Please can you confirm the species (I'm probably wrong). Many thanks!

I am pretty sure you are right with this identification. The East Pacific has quite a few chromodorid species with this colour pattern but this seems to be the only one with the plain white, or bluish white, mantle border. I am glad to get this photo because it is not a very well known species so every record is valuable - if only to give us a better idea of its colour variability.
