The Dobhar Chu is a mythical monster that has inhabited British lakes since ancient times. Thought to be a cross between a giant otter and a hound, the Dobhar Chu is about seven feet long, or about the size of a crocodile. As recently as 2003, Irish artist Sean Corcoran and his wife Miranda had a surprise encounter with a similar creature while camping on Omey Island in Ireland’s County Galway.
