Codium fragile ,known as green sea fingers、dead man's fingers, Scientific Name：Codium fragile, is a type of seaweed called green algae that is found in warm seas around the world. It is found on rocky reefs in the lower intertidal to subtidal zones of oceans throughout Japan. The branches are long and rounded in cross section, looking like a human finger. It is dark green, 1 cm thick, and grows to about 40 cm in length with bifurcated branches. It was eaten as edible seaweed in the Manyoshu period (710-794), but is no longer edible.
Its Japanese name '海松' is derived from the fact that it is found in the sea and its shape resembles a pine tree. In English, it is called "green sea fingers" or "dead man's fingers" because of its green color, the rounded cross section of its branches and leaves that resemble fingers, and the way its branches hang down from rocks at low tide, making it look like the fingers of a dead man.
