Loch Ness Monster
Most scientists believe that the Loch Ness Monster is not real, and they say that many of the sightings are either hoaxes or pictures of other mistaken existing animals. However, a popular theory among believers is that "Nessie" is a plesiosaur, an extinct meat-eating aquatic reptile that lived in the Mesozoic era. The Loch Ness monster has also been described as an elephant, eel, and other animals.
