Avanc

The Afanc (Welsh pronunciation: [ˈavaŋk], sometimes also called Addanc, [ˈaðaŋk]) is a lake monster from Welsh mythology. Its exact description varies, being described as resembling a crocodile, beaver or dwarf-like creature, or a platypus and is sometimes said to be a demon. The lake in which it dwells is also uncertain and it is variously said to live in Llyn Llion, Llyn Barfog, near Brynberian Bridge or in Llyn yr Afanc, a lake near Betws-y-coed that was named after the creature.
