Grateloupia turuturu (Yamada, 1941)

Devil's tongue weed

Description 1

Alga that attaches to the substrate via a base disc of 5-15 mm in diameter form which a long stipe stretches up to 2 cm, gradually extending to a spear-shaped leaf, 10-35 cm long with sharp petals. The colour varies from intense red to pink, occasionally somewhat faded or discoloured by the sun, speckled by whitish dots.

Biology 1

Rapid growth in spring and summer, reaching a length of 1 m. Grows rapidly at hight temperatures and withstands reductions in salinity. During the microscopic phases and juvenile gametophyte and sporophyte phases it can attach to mussel and oyster shells. Heteromorphic life cycle alternating between gametophyte and sporophyte phases. Reproduces by means of gametophytes and sporophytes of similar morphology and living in the same habitats.

Habitat 1

Semi-exposed and protected environments, on rocks and bivalve molluscs, in rocky of mid intertidal zones and on rocky intertidal and infralitoral platforms. Generally associated with marine cultivation. Suits environments influenced by sand, upon exercising an abrasive effect that leaves the substrate ripe for colonization by this alga. Frequently found in areas close to aquaculture facilities and environment subjected to eutrophication.
