[edit | edit source]It is a large, open species with floats longer (4–10 mm) than broad (3–6 mm). The final branches are long (20–60 mm) and thin (1–2 mm). The side branches have smaller branches arising at irregular intervals from all sides, rather than the seaweed having branches in the one plane.[3]
Biochemistry
[edit | edit source]This species contains phlorotannins of the classes of phlorethols and fucophlorethols (phloroglucinol, difucol, tetraphlorethol-E, pentaphlorethol-B, hexaphlorethol-A, fucotriphlorethol-G, fucotriphlorethol-H, fucotetraphlorethol-J, fucotetraphlorethol-K, fucopentaphlorethol-E, bisfucoheptaphlorethol-A, difucofucotriphlorethol-A, difucofucotetraphlorethol-B, terfucohexaphlorethol-B, terfucoheptaphlorethol-A, diphlorethol, triphlorethol-A, tetraphlorethol-C, fucophlorethol-B, fucodiphlorethol-D, fucotriphlorethol-B, fucotetra-phlorethol-B, bisfucotriphlorethol-A, bisfucotetraphlorethol-A, bisfucopentaphlorethol-A, bisfucopentaphlorethol-B, difucophlorethol-A, difucofucotetraphlorethol-A, terfucopentaphlorethol-A and terfucohexaphlorethol-A).[4] There are also halogenated phlorethols and fucophlorethols (chlorinated, brominated and iodinated derivatives).[5]
