Is it the one that can roll when the wind is blowing? Oops wait... I guess not. It is not a seaweed, it is a bush :oops:

Please post a picture of the seaweed that you are speaking of. I am currently taking a course on seaweeds, and have a background with them, as well as with algae.

It is nice and mutual coincident! :) I want to ask about Ulva (Chlorophyceae). I need data of its nutritive content. Could you do me a favour, please? Thank you in advance :)

Are you talking about Bull Kelp Nereocystis luetkeana ? These have large ball type structures on the ends of them. Just a guess really.

Edit: He posted the picture. This post is completely wrong now. Ignore it.

I do not know. They look like clumps of dead grass. Good luck with this one.

As for Ulva, I do not know about its nutritional aspects. I would google that one if I were you.

@Dr. Stein... I found a link for you with some information that could be useful to you in relation to your question regarding Ulva.

Otherwise, I have nothing for you. Hope this helps you out.

Where is the photo? :? Why I can't see that? :(

But, since someone mentioned about "dead grass" it brings my mind to TUMBLEWEED, which one of its well-known gebus is Salsola

For your note, it is NOT seeweed, it is Angiosperm-Magnoliophyta :)

@Volvox: THANK YOU! :D

Can you tell me where the picture was taken? The sea around it is important because species are different depending on the region.
