Identification

Back densely covered with small rounded tubercles grouped into larger compound knobs. Colour ranges from greenish or yellowish brown to dark brown, reddish, pink or grey. Rhinophores have dark stalks and pale, white-flecked clubs; gills similar. The diagnostic feature is the large white circular blotches under the mantle skirt.
