The Loch Ness Monster, bigfoot and the yeti have long held a fascination for people the world over. Debates about their actual existence or what they might really be have continued for decades, if not centuries. Known also as cryptids, they have spawned a body of research known as cryptozoology. This entertaining book looks at the evidence of these mysterious monsters and others and explores what they might really be (if they exist at all), why they have been represented as they have and the development of cryptozoology and how it has collected data to discover more about these unknown creatures.
