Dear Rie,
I think this is a juvenile form of Discodoris lilacina. There are a number of relatively common large 'flat' dorids which I suspect are all forms of the same species, though I would be happy to hear other people's views. At present I know of no good characters to separate the various colour forms. If they are all one species, it appears that the juveniles are more transparent in colour, as in your photo. What they all seem to have in common are two or three white or white and brown patches in the dorsal midline and the habit of breaking off the mantle skirt when they are disturbed.

Best wishes,
Bill Rudman.
