For centuries, the Scottish Highlanders have told of great water beasts said to inhabit particular lochs and burns. The most famous of these is, of course, the Loch Ness Monster, or 'Nessie,' said to be twenty to forty feet long - far larger than any freshwater animal known to exist in the murky, fathomless lake. In this essential primer, world famous cryptozoologist Ken Gerhard presents the most accurate and indispensable information that's been gathered with regard to the Loch Ness Monster - the best evidence supporting its existence, consensus expert opinions up to this point, the most compelling encounters, and really everything you need to know about the subject in order to become Nessie knowledgeable. In addition, Gerhard discusses other celebrated aquatic cryptids, including Champ, Ogopogo, and so-called sea serpents. The reader will get answers to questions such as: Could they really exist? What do they look like? How many are there? Are they dangerous? Where are the remains? Finally, Ken makes an argument that these elusive creatures may be descended from a line of ancient whales, believed to have gone extinct millions of years ago.
