Animal translucent white with bright yellow papillae around the anterior mantle edge. The papillae near the gills are also yellow, as are the tips of the gills and the rhinophores. There is also a median yellow line from the gills to the tip of the posterior foot. Thompson & Brown (1984) also report that black patches can sometimes be present. They also report that in the British Isles this species feeds on the colonial bryozoans Crisia denticulata, Cellepora pumicosa and Bugula plumosa. It can grow to 45mm in length.
