Ulva clathrata is a species of seaweed in the family Ulvaceae that can be found in such European countries as Azores, Belgium, Ireland, Netherlands, and the United Kingdom. It is also common in Asian and African countries such as Israel, Kenya, Mauritius, South Africa, Tanzania, [1] Japan, Portugal and Tunisia. It has distribution in the Americas as well including Alaska, Argentina, Brazil, Cuba, Grenada, Hispaniola, and Venezuela. [2] Besides various countries it can be found in certain gulfs, oceans and seas such as the Gulf of Maine and Gulf of Mexico, Indian Ocean and European waters (including Mediterranean Sea). [1]
The plant is light green in colour and is 20–80 millimetres (0.79–3.15 in) in height. The thin cylindrical threads are 1–3 millimetres (0.039–0.118 in) in width. [3]
It is used in biochemistry, since it has 20-26% content of protein, 32-36% of which are crude proteins. The plant also contains glucose (10–16%), rhamnose (36–40%), uronic acids (27–29%), and xylose (10–13%). [4]
The species is also known by this names in other countries: [1]
The sea lettuces comprise the genus Ulva, a group of edible green algae that is widely distributed along the coasts of the world's oceans. The type species within the genus Ulva is Ulva lactuca, lactuca being Latin for "lettuce". The genus also includes the species previously classified under the genus Enteromorpha, the former members of which are known under the common name green nori.
Sargassum is a genus of brown macroalgae (seaweed) in the order Fucales of the Phaeophyceae class. 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. 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.
Ulva lactuca, also known by the common name sea lettuce, is an edible green alga in the family Ulvaceae. It is the type species of the genus Ulva. A synonym is U. fenestrata, referring to its "windowed" or "holed" appearance, Despite the name, it is not a lettuce
Porphyra is a genus of coldwater seaweeds that grow 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 60–70 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. The species Porphyra purpurea has one of the largest plastid genomes known, with 251 genes.
Caulerpa lentillifera or sea grape is a species of ulvophyte green algae from coastal regions in the Asia-Pacific. This seaweed is one of the favored species of edible Caulerpa due to its soft and succulent texture. It is traditionally eaten in the cuisines of Southeast Asia, Oceania, and East Asia. It was first commercially cultivated in the Philippines in the 1950s, followed by Japan in 1968. Both countries remain the top consumers of C. lentillifera. Its cultivation has since spread to other countries, including Vietnam, Taiwan, and China. C. lentillifera, along with C. racemosa, are also known as sea grapes or green caviar in English.
Ulva intestinalis is a green alga in the family Ulvaceae, known by the common names sea lettuce, green bait weed, gutweed, and grass kelp. Until they were reclassified by genetic work completed in the early 2000s, the tubular members of the sea lettuce genus Ulva were placed in the genus Enteromorpha.
Caulerpa prolifera is a species of green alga, a seaweed in the family Caulerpaceae. It is the type species of the genus Caulerpa, the type location being Alexandria, Egypt. It grows rapidly and forms a dense mass of vegetation on shallow sandy areas of the sea.
Ulva compressa is a species of seaweed in Ulvaceae family that can be found in North America, Mediterranean Sea, and throughout Africa and Australia.
Ulva flexuosa now generally referred to as Enteromorpha flexuosa J. Agardh). is a species of seaweed in Ulvaceae family that can be found worldwide.
Blidingia minima is a species of seaweed in the Kornmanniaceae family. It was described by Johann Kylin in 1947.
Blidingia marginata is a species of seaweed in the Kornmanniaceae family.
Bryopsis plumosa, sometimes known by the common names green algae or hen pen, is a type of green seaweed.
Dictyota is a genus of brown seaweed in the family Dictyotaceae. Species are predominantly found in tropical and subtropical seas, and are known to contain numerous chemicals (diterpenes) which have potential medicinal value. As at the end of 2017, some 237 different diterpenes had been identified from across the genus.
Wrangelia is a genus of red algae in the family Wrangeliaceae.
