Reunion, Etang salé on the rocky coast, less 1 m, 2 January 2012, size : 12 mm

Remarks :

  This species looks like Polycera japonica and Polycera sp. 5 in South Africa in NSSI, Nudibranch & Sea Slug Identification, Indo-Pacific, Gosliner, Valdés & Behrens, 2015
    The presence of large irregular opaque white tubercles all over the body could be considered as polymorphism of P. japonica or aother species, so for the moment I use the term of Polycera cf. japonica
