The body colour is white, while the cerata are light blue with a yellow tip. There can be a pair of orange marks on the head between the rhinophores and oral tentacles. The orange brown rhinophore clubs are papillate posteriorly but along the sides the papillae appear to coalesce into ridges. The foot corners are tentaculiform. They feed on sea anemones and grow to 70 mm in length. Atlantic-Mediterranean species, quite common in temperate-warm waters
