Talk:Seaweed

Seaweeds are to be found among all the major algal groups: the blue-green, red, green, and brown algae.
This simply isn't true. First, there are no seaweeds among the blue-green algae, which are now often not even considered algae. Second, there are several other major groups of algae, such as the diatoms and dinoflagellates, which do not include any seaweeds. -- Josh
I realize that the dividing line between large filamentous forms and microthallic algae as to the term seaweeds in common parlance is fuzzy -- However, we do have three species regarded as "seaweed" in Hawaiian waters that are in the (old) group of blue-green algae (i.e., cyanophytes), and there are terrestrial and freshwater examples (not "seaweeds" of course). Not sure about your second point? I did not list groups that do not have any seaweeds in them. Marshman
I guess you are saying these others ARE "major groups" -- I'd agree with that point, certainly. I'll reword the text. Marshman
That is indeed what I meant. Checking the blue-green algae bit, it seems you're right, so I've added them back to the article (as cyanobacteria, which is a more common name nowadays). Feel free to adjust as you see fit, of course.
I was going to suggest that if phycologists are purists about this "common parlance" name, we could develop a paragraph about it. Maybe if we get further disagreements. Thanks for input. Marshman
