Grateloupia turuturu
Taxonomic Group: Algae


Grateloupia turuturu is a large, conspicuous red alga, often exceeding one meter in length. It is native to the Northwest Pacific from Vladivostok, Russia to Jeju Island, South Korea. It is introduced on both coasts of North America, throughout Europe and North Africa, and in localized regions of Australia and Brazil. It occurs in a wide range of coastal habitats from cold-temperate to warm-temperate regions and grows on a variety of substrates, including bedrock, boulders, cobbles, shells, and artificial substrates, including ship hulls. In some cases, G. turuturu may alter native benthic biodiversity by competing with native algae or reducing invertebrate biomass, but these impacts appear to be localized.
