"Definitely not Nembrotha guttata. Nor is it Nembrotha kubaryana, so I think for now it has to be Nembrotha sp. It can joint that guttata-look-alike, which had white dusting in its pigment pattern. No idea of size, I suppose? There seem to be a clutch of these species with similar spots and colours!"
