Trumpet anemone.

The base is sticky as a suction cup has a column 20 cm long, smooth, not divided into regions and funnel. It is yellowish brown and striped column is sometimes white or blue. The oral disk, which is usually marked by blue or green fields that radiate from the mouth (due to the presence of symbiotic algae), is surrounded by about 100 long and strong whitish tentacles can retract and reach about 6cm (maximum 15cm) long, with tapered ends. The tentacles are of different size and are formed as circles.
