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 😳

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! 😀

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

I don’t recognize them but I can offer you this: They are formed by seaweed being ripped from the bottom of the sea shortly from the edge of the sea. In a location where the movement of the waves is moving in. In all likelihood they are made up of multiple different types of seaweed. One possible type that could be in that mess is:

I would recommend that if possible. Get a sample of the seaweed. Take it to a lab and stick it under a fairly high powered microscope. See what it looks like because that will help you. If you can get a picture of the microscopic view to show us. Here is a site that might help you.
