The Loch Ness Monster is a very large animal, supposed to live in Loch Ness (It's a very deep lake in Northern Scotland.) People say that the Loch Ness Monster doesn't look like any other animal alive today. Although some people believe this creature really exists and say they have seen it, there is no scientific proof and for most people it's just a story. It is often shown in pictures as a creature like a large black or green dinosaur.
