Peltodoris is a genus of sea slugs, dorid nudibranchs, shell-less marine gastropod molluscs in the family Discodorididae.
This genus differs from Discodoris by its lack of labial armature. It feeds on sponges, favouring two genera.
And some of these species, such as Peltodoris nobilis, give off a strong lemony scent when rubbed vigorously.The Seaslug Forum : Peltodoris nobilis
