Identification
The thallus of this red seaweed is composed of cylindrical, fairly brittle branches that taper towards their tips and towards their basal branching point. Branching may be opposite or from all angles of the main axis (radial). This species' colour varies from light pink, to dark red or reddish brown, to straw yellow when bleached in summer. It grows 10-40 cm tall.
Habitat & Range
Sarcodiotheca gaudichaudii grows on rock and other hard substrates, particularly small stones and shells, in the lower intertidal to upper subtidal. on the west coast of North America its recorded range extends from Alaska to Baja California. It has also been recorded in parts of South America, as well as Britain where it was likely introduced. The above specimens were found growing on rock embedded in sand, on Calvert Island's North Beach.
