Distribution This species is known from New South Wales, southeastern Australia and probably also from Northern New Zealand. Description This brightly coloured species is completely pink. Only the tips of the mantle projections, rhinophores and gills have a darker shade of the same color. It does not have a traditionally shaped mantle, but instead has up to seven lateral appendages or papillae that protrude from the main body.
