Sargassum miyabei is a species of seaweed native to East Asia and Southeast Asia, from eastern Russia and Japan to Vietnam and the Philippines. It belongs to the subgenus Bactrophycus, section Teretia of the genus Sargassum . [1]
The Prorocentrales are a small order of dinoflagellates. They are distinguished by having their two flagella inserted apically, rather than ventrally as in other groups. One flagellum extends forward and the other circles its base, and there are no flagellar grooves. This arrangement is called desmokont, in contrast to the dinokont arrangement found in other groups. Accordingly, the Prorocentrales may be called desmoflagellates, and in some classifications were treated as a separate class Desmophyceae.
The brown algae, comprising the class Phaeophyceae, are a large group of multicellular algae, including many seaweeds located in colder waters within the Northern Hemisphere. Most brown algae live in marine environments, where they play an important role both as food and as a potential habitat. For instance, Macrocystis, a kelp of the order Laminariales, may reach 60 m (200 ft) in length and forms prominent underwater kelp forests. Kelp forests like these contain a high level of biodiversity. Another example is Sargassum, which creates unique floating mats of seaweed in the tropical waters of the Sargasso Sea that serve as the habitats for many species. Many brown algae, such as members of the order Fucales, commonly grow along rocky seashores. Some members of the class, such as kelps, are used by humans as food.
The Sargasso Sea is a region of the Atlantic Ocean bounded by four currents forming an ocean gyre. Unlike all other regions called seas, it has no land boundaries. It is distinguished from other parts of the Atlantic Ocean by its characteristic brown Sargassum seaweed and often calm blue water. A similar Sargasso sea is not found in the South Atlantic Ocean
Sargassum is a genus of brown macroalgae (seaweed) in the order Fucales. Numerous species are distributed throughout the temperate and tropical oceans of the world, where they generally inhabit shallow water and coral reefs, and the genus is widely known for its planktonic (free-floating) species. Most species within the class Phaeophyceae are predominantly cold-water organisms that benefit from nutrients upwelling, but the genus Sargassum appears to be an exception. Any number of the normally benthic species may take on a planktonic, often pelagic existence after being removed from reefs during rough weather; however, two species have become holopelagic—reproducing vegetatively and never attaching to the seafloor during their lifecycles. The Atlantic Ocean's Sargasso Sea was named after the algae, as it hosts a large amount of Sargassum.
The Dolly Varden trout is a species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. It is in the genus Salvelinus of true chars, which includes 51 recognized species, the most prominent being the brook, lake and bull trout, as well as Arctic char. Although many populations are semi-anadromous, fluvial and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus or Arctic char complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.
Nostoc is a genus of cyanobacteria found in various environments that forms colonies composed of filaments of moniliform cells in a gelatinous sheath.
Porphyra is a coldwater seaweed that grows in cold, shallow seawater. More specifically, it belongs to red algae phylum of laver species, comprising approximately 70 species. It grows in the intertidal zone, typically between the upper intertidal zone and the splash zone in cold waters of temperate oceans. In East Asia, it is used to produce the sea vegetable products nori and gim. There are considered to be 60 to 70 species of Porphyra worldwide and seven around Britain and Ireland where it has been traditionally used to produce edible sea vegetables on the Irish Sea coast. Porphyra is a chief source of plant-based vitamin B12.

Acer miyabei is a species of maple native to Japan, where it occurs in Hokkaidō and the Tōhoku region in northern Honshū.
Saccharina japonica is a marine species of the Phaeophyceae plant, a type of kelp or seaweed, which is extensively cultivated on ropes between the seas of China, Japan and Korea. It is widely eaten in East Asia. A commercially important species, S. japonica is also called ma-konbu (真昆布) in Japanese, dasima (다시마) in Korean and hǎidài (海带) in Chinese. Large harvests are produced by rope cultivation which is a simple method of growing seaweeds by attaching them to floating ropes in the ocean.
Oxyrrhis is a genus of dinoflagellates. It includes the species Oxyrrhis marina.
Sargassum muticum, commonly known as Japanese wireweed, is a large brown seaweed of the genus Sargassum. It is an invasive seaweed with high growth rate. It has an efficient dispersion thanks to its floats.
Sargassum pallidum is a species of seaweed native to East Asia and Southeast Asia. It belongs to the subgenus Bactrophycus, section Teretia of the genus Sargassum. Along with Sargassum fusiforme, S. pallidum is often dried and processed into a traditional Chinese medicine known as Hai Zao or Herba Sargassi.
Cystoseira crassipes is a species of seaweed native to northeast Asia.
Perkinsidae is a family of alveolates in the phylum Perkinsozoa, a sister group to the dinoflagellates.
