External morphology Body elongate, thick, background colour transparent to beige with darker dorsum. Cerata rounded, globular, beige to semi-transparent in colour, with blunt and dark brown digitations on top and white dots concentrated under these digitations. Rhinophores divided into a ‘Y’ shape. Ecology Specimens found on unidentified red algae; juveniles were found in February. Slugs were active at night and usually under rocks in areas with abundant algae during the day. Distribution Originally described from Greece (Thompson 1988); the Adriatic Sea and Italy (Ballesteros et al. 2012–2021); Spain: Balearic Islands (GROC 2009–2021), Catalonia (Ballesteros et al. 2016; this study). Remarks Easily differentiated from other Mediterranean Cyerce species by its rounded parapodial margin and digitate cerata tips, whereas C. cristallina has an angular parapodial margin and roughened but not digitated cerata apexes (Thompson 1988).
