A dog walker was left spooked after finding a rubbery pile of strange, worm-like creatures on the beach.
Katie Tootell has walked along the same beach in Anglesey, for 12 years, with her dogs.
After so long, she knows the beach well, and what to expect there, but was left stunned on her walk on Monday 3 April along the beach in Traeth Lligwy, near Moelfre.
