Green Marine Worms - Jersey 2008. Symsagittifera roscoffensis - Thanks for ID Perseus1
From what I can remember being told by our guide, these swarming bright green marine worms (common name Mint Sauce Worms) are rather uncommon, (or maybe he said uncommonly seen??) so just a bit of a record shot to back up the image from my laptop. The tidal range on Jersey is one of the highest in the world - the tide can rise and fall in excess of 40 feet twice a day. It's a great place and I will definitely return.
