This species grows to about 25 mm in length. It is distingusihed by the reddish brown or black streaks and patches on the body, and the cerata which have reddish brown or black terminal spots on the ceratal tubercles, and similarly coloured streaks on the ceratal skin between the tubercles. There are 7-8 pairs of cerata, each with seven circlets of rounded tubercles. This species feeds on the calyptoblastic hydroid Kirchenpaueria pinnata. Described by Lemche from Galway Bay, Ireland, D. dunnei is now known also from west Scotland (near Oban), from Northern Ireland and from Lundy Island in the Bristol Channel. Outside Britain it is known only from Galicia (northern Spain).

There are many species of Doto reported from the North Atlantic. Bernard Picton's website Nudibranchs of the British Isles has a comprehensive coverage of most of the species.
