What is Seaweed?

Seaweed Laver Extract Seaweed Extract.CAS.RN.NO:90046-12-1 photo picture image From the polars to the tropics, estimates range from 20,000 to 130,000 species of seaweed can be found, but the real figure is probably around 45,000. Between the United States and Africa in the North Atlantic Ocean, lies a free-floating meadow of seaweed almost as large as a continent. This is the famous Sargasso Sea. Christopher Colombus is said to have discovered it as he sailed toward the New World in 1492. Its presence suggested that land was near and encouraged him to continue on. Seaweed plays an important and vital role in the marine ecosystem, providing food and shelter for a host of creatures such as green sea urchins, lobsters, and young fish. It is also an important resource for people. Almost all are algae, which is one of the simplest forms of plant life because they have no roots, stems, leaves, and flowers. This is perfect for the kind of life they live with the constant pounding by the sea. Most of these seaweeds can be seen thriving in underwater beds, floating along the sea surface, and attached to rocks and piers. Seaweeds are divided into three major groups by color: the greens, the browns, and the reds. They cover rocky shores in horizontal bands, with the green seaweeds growing along the high-tide line, brown seaweeds found between the high-and low lines, and red seaweeds living in the waters below the low-tide line. This zonation is regulated in large part by the light availability and by how sunlight penetrates the seawater. Blue wavelengths penetrate ocean waters to greater depths than orange-red wavelengths. Thus red seaweeds (which absorb mostly blue light) are found at the greatest depths, in some cases to more than 70 feet; brown seaweeds are intermediate, and green seaweeds (which absorb mostly red light) are found near or at the surface. Certain red algae has been recorded at growing depths of 270 m.(885 ft.), far deeper than any other known plant life in earth.
