Full frontal bristleworm
A terebellida polychaete, probably Lanice sp. They usually poke vertically out of the sand at low water springs but something had hoiked this one out. It was 7cm long. Natural history does not get more exciting than this. Polychaetes are segmented worms that include earthworms in your garden (there is an Earthworm Society of Britain), Ascaris lumbricoides (a parasitic worm that can be more than a food long, lives in the human small intenstine and is estimated to infect more than a billion people worldwide) and an un-named inch-long polychaete that has been seen at the bottom of the Challenger Deep, the deepest sea in the world.
