The Loch Ness Monster: just about everyone has heard of it. A large number of people claim to have seen the long-necked, humped leviathan of the deep. Some have even photographed and filmed it. Nessie, as the beast is affectionately known, has been a staple part of the world of the unexplained since 1933, when the phenomenon of the monster exploded in spectacular, planet-wide fashion. Since then, millions of people have flocked to the shores of the 22.5 miles long and 744 feet deep loch, all in the hopes of seeing the elusive creature. Attempts have been made to seek out Nessie with sonar-equipment, aircraft, balloons, and even submarines. Theories abound as to what Nessie is – or, far more likely and correctly, what the Nessies are. Certainly, the most captivating theory, and the one that the Scottish Tourist Board, moviemakers, and the general public find most appealing, is that which suggests the monsters are surviving pockets of plesiosaurs. They were marine reptiles that the domain of zoology assures us became extinct tens of millions of years ago. The possibility that the monsters are actually giant-sized salamanders holds sway in more than a few quarters. As does the idea that perhaps massive eels are the culprits. Then there are scenarios involving sturgeon, oversized turtles, catfish, and even crocodiles, giant frogs, and hippopotami! Yes, really.
