The Loch Ness is a lake in Scotland that holds the largest volume of freshwater in the United Kingdom. But rather than being known for its size, it is famous for the mysterious legend of the Loch Ness monster. For hundreds of years, people have reported catching a glimpse of a huge creature in the lake while others have shared photos they claim to have taken of this sea creature. The legend is so great that even scientists have been intrigued and many have conducted experiments and come up with theories to try and explain what people could be witnessing.It has been proposed that Nessie, as the Loch Ness monster is commonly called , could be a prehistoric creature called a plesiosaur, an animal that spanned up to ten meters in length and has long been considered to be extinct. Adrian Shine, the leader of a British team called the Loch Ness Project, has spent over 30 years trying to rationally explain the monster sightings by researching the ecology of the region.

If in fact a large creature was living in the lake, there would have to be evidence of a food chain for it to survive. A creature like the Loch Ness monster would most likely eat fish, which in turn would live off large quantities of microscopic animals called zooplankton. There would have to be enough zooplankton in the lake to support populations of larger animals.

This dont really make sense to me. The legend must be old about a huge creature living in Loch Ness, i cant remember but i think i've seen photographs + reports dating back to around 1800 - 1900, from them til today, the creture itself must be over one century in age! Ok, turtles, clams etc can live longer but still, big creatures dont always live long. Plus, if its a Plesiosaur as scientists predict, thats going to blimin' huge to live in a 'River'!! Also, huge animals - lots of food + lots of space. It'll need a lot of food + space to survive, in a river wouldnt be enough... would it? 10m long? Also, if Plesiosaurs do not live long, how can one survive this long? wouldn't there be more than one for the legend to continue and still be 'active' in 2007? Still, wat i can see here is a Huge immortal/long living, thought to be extinct creature living in a river in the UK, sounds a bit odd to me really, but if this 'Plesiosaur' really exists with hard evidence, cant wait to hear about it!!

I think that there are underwater passageways that Nessie swims through that lead to other bodies of water nearby. Our Earth is covered nearly 97% with water, that leaves many unobserved and unknown areas. If one did exist in the late 1800's then it is understandable to believe it to be dead but why can't there be multiple Nessies? Just think of how much is still undiscovered in our waters!
