The continuous ridges, the encircling rings, and all-black rhinophores are typical of P. rosans.Comment from Richard Willan on photo #21221

A very atypical individualComment from Richard Willan on photo #1530
A typical individual as regards the elongate and sinuous shape of the pustules on the mantle, but the pale areas on top of these pustules are severely overexposed – they are normally pale rose-pink in life (not white).Additional comment from Dr. Nathalie Yonow: Afraid I can’t ID this one. No rhinophores, no size, and not too clear. Probably a Phyllidiella. It has a pale mantle margin like pustulosa, but it isn’t Phyllidiella pustulosa. Both Phyllidiella burni and Phyllidiella nigra have black mantle margins. Sorry.
