Comment from Alexander Martynov on photo #4032
This is a colour variation of common North Atlantic species Polycera quadrilineata (Müller, 1776). It is an interesting case when some colour morphs of one species (e.g. Polycera quadrilineata) may approach colour variants of another species of the same genus (e.g. Polycera atra), significantly differs in other features.Locality:
