Laminaria digitata. Laminaria digitata is a tough, leathery, dark brown seaweed that grows to 2 or 3 metres (6 + 1 ⁄ 2 or 10 ft) long. The holdfast which anchors it to the rock is conical and has a number of spreading root-like protrusions called rhizoids.
Laminaria is a genus of brown seaweed in the order Laminariales (kelp), comprising 31 species native to the north Atlantic and northern Pacific Oceans. This economically important genus is characterized by long, leathery laminae and relatively large size.
In Russia, especially in the Russian Far East, and former Soviet Union countries several types of kelp are of commercial importance: Saccharina latissima, Laminaria digitata, Saccharina japonica. Known locally as "Sea Cabbage" (Морская капуста in Russian), it comes in retail trade in dried or frozen, as well as in canned form and ...
Laminaria hyperborea is a species of large brown alga, a kelp in the family Laminariaceae, also known by the common names of tangle and cuvie. It is found in the sublittoral zone of the northern Atlantic Ocean. A variety, Laminaria hyperborea f. cucullata (P.Svensden & J.M.Kain, 1971) is known from more wave sheltered areas in Scandinavia.

Fucus species can also be used for thalassotherapy, along with other species such as Turkish towel (Chondracanthus exasperatus), feather boa (Egregia menziesii), and finger kelp (Laminaria digitata). [9] In 2005, it was announced that bacteria grown on Fucus have the ability to attack and kill the MRSA superbacterium. [10]
It may reach lengths of about 2.5 m. It overlaps to a small degree (+) in distribution with Fucus serratus and somewhat more with Laminaria digitata. It has low and high light limitation values of about 5 and 70 W per square meter respectively. Its distribution is also limited by salinity, wave exposure, temperature, desiccation and general stress.

In a representative species Laminaria, there is a conspicuous diploid generation and smaller haploid generations. Meiosis takes place within several unilocular sporangium along the algae's blade, each one forming either haploid male or female zoospores. The spores are then released from the sporangia and grow to form male and female gametophytes.
