Adult individuals can hardly be mistaken for any other species in Norwegian waters. The color is usually brown, but red, olive green or purplish black individuals have been reported as well. There are white splashes and small, dark spots on both body and tentacles. In Norway, the length does not exceed 7 cm, but specimen 20 cm long are registered further south. On the head there is a pair of mouth tentacles in the front and a pair of head tentacles at the top.
Aplysia punctata is the most common sea hare in Norway. It is often found between seaweeds, not far below the tidal zone.
This sea hare is registered in the North-East Atlantic Ocean, from Greenland and Norway to the Mediterranean.
