Usually white, sometimes with a number of milky yellow glands on the mantle skirt. In rare cases the edge, or the whole mantle is tinged with yellow. It feeds on encrusting slime sponges, in particular Halisarca dujardini. It appears to be a winter breeder, the eggs hatching in about 50 days as small crawling slugs, with no planktonic larval stage.
