Red Seaweeds can be many colors including, but not limited to, bright red, pink, purple, deep red, grey and black. They are the most abundant of the three divisions of seaweeds in our Pacific Northwest waters with approximately 265 species.  They do not require as much light to grow as the green or brown seaweeds so they are found from the intertidal areas to depths of 25m.  Red seaweeds are commonly harvested for their carrageenan, which is added to food to give it a smooth, creamy texture. Porphyra is harvested for nori used in asian cuisines.
