Loch Ness Monster

The Loch Ness Monster, as it is popularly known, is actually the world's largest Kelpie. It's favourite shape is that of a Sea Serpent. Wizard observers from the International Confederation of Wizards discovered it was a Kelpie when they observed it changing into an otter on the approach of a team of Muggle investigators, then back into a Sea Serpent. The Office of Misinformation has worked diligently, convincing the Muggles that all photographic evidence of "Nessie" is actually fake.

Rubeus Hagrid once offered the use of the lake at Hogwarts School of Witchcraft and Wizardry to house the creature.
