Appearance
This species can grow to 25 cm high and can reach a diameter of 1 metre, making it one of the largest species of anemone. The tentacles are long and slender, taking the shape of a red column. The tubercles on the column are big and rough, having a white colour. They are organized in circular rows which protrude from the column. Unlike other species which may accumulate matter, the tubercles do not attach to ocean debris such as bits of shell. The column is red in colour.
No special spherules are present around the external rim of the oral disk beyond the tentacles.
