Seaweed



Keyword Definition

Seaweeds are marine macroalgae of which more than 40,000 species are known; approximately 650 species are found in northeast Pacific ocean waters.  They can be classified into three main groups according to their habitat and colour: 1) green seaweeds (Class Chlorophyceae), mostly from the upper tidal zone; 2) brown seaweeds (Class Phaeophyceae), mostly in the mid-tidal zone; 3) red seaweeds (Class Rhodophyceae), mostly from the low tidal zone.  Along the fjorded inlets of western Norway, Greenland and Canada, by far the most common seaweeds in the intertidal zone are the brown rockweeds (Fucus spp.), also known as wrack or bladderwrack.
