Beadlet anemone  (Actinia equina)

Very common on most rocky shores of Britain. Elsewhere, this species is found from the White Sea in Russia to the West coast of Africa, and is found in the Canary Islands and the Mediterranean (4).

This anemone attaches to hard surfaces and is found from the upper to lower shore, down to depths of 20 m (2). It can also tolerate brackish water and may be found in estuaries (1).
