The most distinctive feature of the Flower Butterfly Seaslug (Cyerce sp. /Cyerce cf. bourbonica) is its translucent, brownish cerata adorned with spots, scattered white marks, and highlighted edges that bear a resemblance to a mollusk shell. The rhinophores are forked and transparent. The juveniles are more colorful than the fully grown butterfly sea slugs of this species. This species is still undescribed.

Please note that this Cyerce is not Cyerce bourbonica, who has cerata with margins that are pale violet-blue with creamy orange patches and black spots.
