Cerianthus membranaceus is a large tubiform anemone. The oral disc can have a diameter up to 40 cm. There are two spirals of tentacles. Those in the outer spiral are long, slender and armed dicycidocytes (stinging cells) and are used to capture prey. The tentacles in the inner spiral are shorter and work to transfer the captured food to the central mouth.

The tentacles are sometimes banded and are available in a range of colors; white, yellow, orange, green, brown, blue, black and purple. The color of the inner spiral often contrasts with that of the external spiral.

The column of this anemone tube secretes the mucus in which a unique type of cnidocytes are incorporated which come together to form a fibrous structure. Sand and other particles adhere to this and form a leathery protective tube up to 40 cm in length. The tube is open at the base which allows water to escape when the animal retracts.
