These marine algae have a bulbous base that aids to anchor them to the sandy bottom. They are anisogamous; male and female gametes are borne on different plants. The night before the gametes are released, the whole plant, except for the gametes, loses its green colour. After the gametes are released, the thallus would consists only of the encrusted cell wall. The wall will eventually break down and form part of the sediment.
