Codium tomentosum is a small green seaweed 22cm long with a dichotomously much-branched, cylindrical frond (from 8 to 10 millimeters in diameter), which has a gentle autumn color, a kind of a dry olive green. The frond is solid and spongy with a felt-like touch and has many colourless hairs which can be seen when the plant is immersed in water. The holdfast is disc-like and formed from many fine threads, giving it a uniform appearance. Codium tomentosum is a perennial species of the infra-littoral, attaches to exposed rocks and occurs in deep rock pools on the lower shore.
