<strong><a href="http://paranormal.about.com/cs/sealakemonsters/a/aa051203.htm" target="_blank">LENGTH</a>:</strong> 15 to 40 ft. <strong><a href="http://paranormal.about.com/cs/sealakemonsters/a/aa051203.htm" target="_blank">WEIGHT</a>:</strong> About 2,500 lbs. <strong>LOCATION:</strong> Scotland The most famous evidence of the Loch Ness monster, commonly referred to as Nessie, surfaced in 1934, but belief in Nessie goes all the way back to <a href="http://www.timelessmyths.co.uk/loch-ness-monster.html" target="_blank">7th century writings</a>. We owe this now-infamous image, referred to as “The Surgeon’s Photograph,” to Dr. Robert Kenneth Wilson, who snapped it while he was visiting the Scottish Highlands. Many people have claimed they’ve seen the creature since then, but each sighting has yet to be confirmed. Spooky! <em>Correction: A previous version of this slide mislocated the loch in Ireland.</em>
