This solitary sea squirt may grow to a length of 6 cm. It is usually pale green or beige in color. There are small red or white spots around the openings (siphons). The inlet siphon is at the top and the outlet siphon at one third of the body height.
This sea squirt is probably widespread along the entire coast of Norway, although it is not as common on diveable depths as A. mentula and A. virginea. It is usually found on stones or shells from lower shore to deep waters, but also lives in crevices where it fills the space available. This may explain why it rarely seen by scuba divers.
It is registered along the European coasts, from Norway and the Faroes to the Mediterranean.
