Animal green, often with translucent white spots all over. There is a characteristic pattern of mottled white pigmentation. The rhinophores are mottled white and there is a band of this colour extending along each side of the head from the base of each rhinophore. A similar coloured band runs around the edge of the parapodia, and along the edge of the foot, and forms a median line down the foot, behind the parapodia, to the posterior tip. The parapodia and foor have scattered papillae which are often pigmented white.
