Main Ref.	Wirtz, P., O. Ocaña and T. Molodtsova, 2003
Remarks	Occurs at the water line, especially in sheltered places such as the inside of harbor walls (green Actinia), red Actinia can occasionally be encountered in the intertidal zone of Azores (Ref. 201)); Common run on the rocks, the surface to a few meters of depth (Ref. 363). Also found in infralittoral zones (Ref. 85338). Solitary (Ref. 2377).
