Remarks :

Identification confirmed by Kathe Jensen
    According Kathe Jensen :" Your Elysia sp. 3 looks like the species labelled Elysia sp. 6 in Terry Gosliner's old book from South Africa (Elysia sp 8 in Gosliner, 2008), or the one called Elysia sp. 10 in the Sea Slug Forum "

Bibliographic data :

The lobes gradually diminshing in size from the front to the back
    The background colour of the body and parapodia ranges from translucent clear to greenish, probably dependent on the stage of the feeding cycle.
    This species is similar to Elysia lobata but has a distinctive color pattern. In Elysia lobata the rhinophores have a bluish tip and at the parapodial edge there is a broad translucent pinkish marginal band which has regularly spaced deeper pink patches
