The dark stripes on a vivid white, beige or yellow background is very characteristic for the candy striped flatworm. It cannot be confused with any other species in Norwegian waters. The body may reach a width of 25 mm and a length of 50 mm. The two tentacles at the head end are speckled with a large number of small eyes.
It is often seen on rocky substrate, preferably with a thin layer of sediments. It seems to prefer depths between 10 and 30 meters.
It can be found along the coasts of Europe, from the western Mediterranean to Norway.
