Kappaphycus and other Gigartinales species are grown commercially for the extraction of carrageenan, a gel used in many food products. However, other studies have suggested Archaeplastida is paraphyletic. Around 6,500 to 10,000 species are known, nearly all of which are marine, with about 200 that live only in fresh water.

The finest organic seaweeds lovingly hand-harvested from the nutrient-rich Atlantic Irish shores. Several species of this type of algae are used as food crops in parts of the world. Because there has been a bit of discussion recently on 'beard' algae (both on this list and in the May issue of FAMA), I thought I would share an article that I have been working on.
