What is Seaweed?

The term "Seaweed" refers to a variety of macroalgae (or large algae) that may be found in the ocean, rivers, lakes, and other bodies of water. 


Seaweed comes in a plethora of colours, shapes and sizes, totalling around 10,000 different species, including at least 555 species in Indonesia alone. Seaweeds are often classified by their colour: Rhodophyta (red), Chlorophyta (green) or Phaeophyta (brown). Seaweeds vary greatly in size, from only a few millimeters long, to massive kelp that grow in dense “forests” and rise like underwater trees from their seafloor roots.
