This is a large, greenish-grey to off-white species, growing to 60–80 mm. It has up to one hundred short, conical tentacles that are transparent to pale greenish to greyish-white, to pale brown, grouped into three rows. On the column, there are vertical rows of adhesive bumps (verrucae) that are relatively darker than the rest of the body. The tentacles also have horizontal black bands. The oral disk varies in colouration, and is sometimes red, green, black or white, and may have streaks of darker colour radiating outward from its mouth. This species can be recognized by gravel, bits of shell or coarse sand that it attaches between its tentacles. Learn more about Sand Anemone
