Bladder Wrack

 bladder wrackWhen I picked up this piece of bladder wrack at Sandsend it looked fresh but it has dried out so much that I doubt it would plump up if I soaked it in water.

As I mention in the note, it has pairs of gas-filled bladders on either side of the midrib of the frond.

It is found in the middle of the intertidal zone on rocky shores.
