These amphipods were provided with a choice of macrophyte material representing brown and red algae and seagrass in a series of preference experiments in the laboratory and field. While seaweed is a type of algae, the two have major differences, in terms of history, the range of species, habitats, and even the cellular structure. Red, brown, and green algae are the three types of algae mainly classified based on the type of photosynthetic pigments present in them. farming of seaweed. one important phycocolloids used as stabilizer and emulsifier in manufacture of dairy products and etc. ...

Intertidal or shallow soft bottom habitats include mudflats and seagrass meadows, which are economically and ecologically important, but in geographic terms comprise only a small part of this extensive habitat type. Further, the macrofaunal community structure in seaweed farms showed more similarities to that on the sand bank than in the unfarmed seagrass beds. However, there is no particular definition for the term seaweed, as there is no one common ancestor to seaweeds, but is a more common term to describe a certain group of plants with distinctive properties. Sushi is made from seaweed, another denizen of the shallow coastal waters — but the similarities end there. Most people assume it's seaweed or grass because of its surface similarities, but in fact, is quite different.
