Habitat :Codium fragile is native to the Pacific Ocean. The species inhabits the middle and lower intertidal zone as well as subtidal regions of rocky shores.

It is also found in large tide pools permanently filled with water. Therefore it is found at Race Rocks. At Race Rocks in 2001, the species occurred in only two small areas, although it was found when diving in earlier years in larger beds, shallow subtidally on the south side of Bentinck Island just across Race Passage north from Race Rocks. On the north side of the Great Race, there was one plant in a tide pool, and on the South East side, several dozen plants have occurred since the early 1980’s along the zero tide level of the small peninsula island. In 2004 it has been observed in several tidepools however its population still remains limited.

Description:
Codium fragile is a dark green alga, ranging from ten to 40 cm high and consists of repeatedly branching cylindrical segments about 0.5 to 1.0 cm in diameter, and the branches can be as thick as pencil. The segments look like dark green fingers. Its holdfast is a broad, sponge like cushion of tissue. The tips of segments are blunt and the surface is soft, so it is sometimes mistaken as a sponge. Its body consists of interwoven, filamentous cells with incomplete crosswalls forming the inner part of the branches.
