THE WALES SEA MONSTER
Sunbathers and beachgoers at Wales were shocked and sickened when a six foot writhing log of gooey tentacles washed up on the shore. It turned out that the monster was actually a colony of goose barnacles attached to what is most likely a log (although it was impossible to see what they were attached to due to the fact that they covered every square inch of it).
Goose barnacles usually live in on the ocean floor. It's possible that currents or rotting caused their perch to become dislodged and float on ocean currents.
