Identification confirmed by Nathalie Yonow (Seaslugs of the Red Sea, p 155)
This specimen look like to A. pikokai, a species
known from Hawaii and Marshall Ids, Aldisa sp 6 in NSSI, Nudibranch & Sea Slug Identification, Indo-Pacific, Gosliner, Valdés & Behrens, 2015 and et à Aldisa sp 1 du livre de Yonow (2008)
and Aldisa sp 1 from Yonow (2008)
Bibliographic data :
Species of Aldisa
tend to be very good at camouflaging themselves to look like sponges.
They often have two or three marks or pits in the midline to mimic the
exhalant pores (oscules) of the sponge colonies. This animal has
certainly developed the imitation pores to a greater degree than we can
recall in any other species.
This specimen looks like Aldisa fragaria , but in Aldisa fragaria there are brown to black tubercules surrounded by a lighter ring
