    I recall seeing something similar at a little museum in B.C.: balls of pine needles tossed about in a river/creek/stream. Fascinating!

    Everyday, I learn something new or see something beautiful on this page. What a wondrous world we live in and don’t even see. Even this tiny ball of grass is a marvel to behold.

    Also somewhat reminiscent of dung beetle balls.

    This is great to see and read about. Having grown up on the the ocean off the barrer reel Island called Plum Island, in Newburyport Massachusetts. I appreicate learning of other parts of the world.
    As a child we often played with ocean plants that would wash up on the beach. After hurricanes many things from far away would show up also.
    Thank you,


    My compliments to the handler on a well maintained cuticle.

    Wow, I’m soooo happy to see this!!! I collected some of these from the beaches of Crete many years’ ago, because I thought they were unusual and beautiful. Always wondered what they were/where they came from & didn’t really know how to go about finding out. Now I know!
    Thank you very, very, very much Daniel and Jackie, you’ve solved a mystery for me. Ahhhhhh…..

    I’m jumping in a bit late here, but I was wondering if anyone had any further information about these claims. It says “scientists”, but I was unable to locate any peer-reviewed sources for that in a cursory search. Any help here?

    Posidonia fanclub – we saw some on a beach in Sardinia this year and Clare met them off the South of France and is in love with them. So much that she’s standing here speechless (very unusual for Clare!). We have a posidonia resting against the keyboard and think its amazing. Rob? posting above – we also took photos of a dung beetle rolling his ball of dung. We still can’t believe it’s the action of the sea that forms such a perfect sphere.

    Thanks a lot for this information. It was a kind of a miracle for me, really couldn’t imagine what these little balls on the beach of Sardegna could be. But now I know :-))
