Distinguishing features
This is the largest of the fish-hosting anemones, up to a metre in diameter. The oral disc follows the contours of the substrate, held in place by orange to purplish adhesive warts (veruccae) on the white column. The column attaches to hard substrate, usually on reef slopes, The colours of the column and veruccae are distinctive but the colour of the tentacles is variable. Tentacles are mostly short (10 to 20 mm) but some in patches may be longer; tentacle tips are blunt or slightly pointed.
