Thanks Bill-- i recognize 3 or 4 different types of sea weed-- and even have been know to eat it-- but I only know two "names": Kelp and Carrigeen-- both of which i have eaten, but I don't know if i would recognize them at the sea shore!

I've eaten kelp chopped, and made into a vegetable pate-- quite good, and carrigeen as a "blache monge". a jellied, milk dessert.
