Stories of a plesiosaur-like creature living in the depths of Scotland's Loch Ness, a very deep lake, have been surfacing for years. Investigations, searches, sonar studies, and multiple other search functions have been conducted to solve the mystery—so far evidence is still inconclusive. Some think "Nessie" is a modern-day dinosaur that somehow managed to survive the mass extinction the rest of its kind suffered, others think people have taken bad photographs of water birds or small boats. All readers, even the most reluctant, will be intrigued by this fact-filled discussion.
