General Description

Firm, globe-shaped alga attached to rock surfaces. Dark green. Up to 12 cm diameter (thallus).

Biology

Like all Codium species, this seaweed is composed of only a single cell and can repair itself if damaged. It appears fluffy underwater and feels velvet-like out of water due to hundreds of tiny hair-like filaments on its surface.
