Nessie The Loch Ness Monster is a phenomena that has often been investigated over the years. There has never been an conclusive information to confirm, or deny, the truth of the Nessie stories.
Numerous photographs have been taken and inspected by experts who were almost determined to detect fraud, but a few of these have never been explained.

This was published in a local newspaper in Loch Ness, Scotland.
This loch monster was first photographed in 1933 after many years of rumours about its existence. 'Nessie Watching' is still a popular pastime in this area. The Loch itself is dark and moody and given to sudden changes of light and weather, so it provides the perfect back drop for monster stories.
Scientists have explored the Loch using sonar and radar and Japanese team even used a mini submarine, but the evidence is still inconclusive. It has been suggested that Nessie could be some kind of pleiosaur that has been left behind from the age of the dinosaur. However, it is doubtful that Loch Ness could provide sustenance for pleiosaurs.

The debunkers of the story say that all the photographs taken are of driftwood, bark and weed. A new theory currently being investigated is the Nessie is in fact a giant European eel that has become sterile and doesn't make its way back to the Sargasso Sea to breed. This would account for some of the out of the water sightings.
