Like C. fragile, Codium setchellii patches are composed of a single cell made of interwoven filaments packed with nuclei and chloroplasts.  Individual dark green or greenish black cushions are soft and sponge-like up to 2 cm (3/4 inch) thick and 25 cm (10 inches) in diameter.  It can be found with C fragile on high energy beaches in the lower intertidal.
