Maroon Anemone Video Stock Footage

Actinia bermudensis attaches itself to a rock surface by its pedal disc, which can reach 2.5 centimetres (1 in) in width. The column is narrower at the top than the base and can reach 5 centimetres (2 in) 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. In most of the range, the acrorhagi are blue, but in the waters off northern Florida, they are pink. Actinia bermudensis is an omnivore. The main items of prey are gastropods, isopods and small bivalves. Other food items may include other marine invertebrates and algae. Many sea anemones form a symbiotic relationship with zooxanthellae. Actinia bermudensis often contains these flagellate protozoa living within its tissues but they are of a non-photosynthetic species. It is doubtful whether this should be called symbiosis as the anemone does not seem to derive any benefit from the arrangement. At times of food scarcity, however, the anemone may consume the zooxanthellae. Learn more about Maroon Anemone
