Found this and several other sea grass (Zostera marina) plants washed up on the little beach called Porthmynawyd near Pointz Castle, north Pembrokeshire on saturday. This a subtidal species which only occurs in a few places in Pembrokeshire; in Milford Haven and in north haven, Skomer island. The plants were very fresh and were brought ashore by the stiff southerly breeze and I'm guessing from north haven on Skomer. Unless there is some uncharted sea grass bed nearby, though unlikely as sea grass like shallow, sheltered conditions. I might be going for a snorkel near this beach in the summer just to check! Nice find anyway...
