This is a relatively small anemone. It may reach a height of 6 cm, a base diameter of 7 cm and oral disk diameter of 5 cm. In Norway red seems to be the most frequent color, but green, violet and brown individuals exist as well. It has a large number of stout tentacles of moderate length.
The beadlet anemone can often be seen as small, jelly-like blobs, exposed by the low tide. It is rarely registered deeper than 20 meters, and is most frequent in intertidal pools. It is very robust and may survive large temperature variations as well as hours on dry land. For this reason it is a popular inhabitant in many aquariums.
This is a common anemone in the Atlantic Ocean, from the west coast of Africa to Russia.
