Isn't it odd:
The Welsh have dragons. So powerful is this image in Welsh lore that they even put one on their flag.
The Scots have fabled beasties or monsters in Loch Ness and Loch Morar.
The English have a tradition of giant Worms.
Dragons beasties wormes and monsters turn up in the lore of unrelated and unconnected peoples around the world.
Maybe there is something going on that most people have failed to notice.
