Maroon Anemone

Actinia bermudensis attaches itself to a rock surface by its pedal disc, which can reach 4 centimetres in width. The column is narrower at the top than the base and can reach 5 centimetres in height. Near the top is a ring of bulges called acrorhagi which contain many cnidocytes. The oral disc has a central mouth and two irregular whorls of 96 to 140 short, retractable, tapering tentacles which are armed with cnidocytes. The general colour of the anemone is dark red or maroon.

Actinia bermudensis occurs in the West Indies, Bermuda and northern Florida, Greece, Caribbean pool, West Atlantica and there is a further, isolated population off Brazil. It is found in the intertidal and the sublittoral zone. It is usually found near the base of rock walls, under overhangs, in caves, in crevices and under boulders.
