Taxonomic Group: Algae


Colpomenia claytoniae is a brown seaweed which grows as a baglike or globular algae attached to hard substrates. It is native to Asia from Japan, Korea and China, and its native range may also extend into the Indo-Pacific. An introduced population was collected in Southern California in 1999, and it full non-native distribution on the West Coast of North America is unclear. It typically grows on rocky substrates in the low intertidal zone and no ecological or economic impacts have been reported.
