What could Nessie Be?

    There are many a thing that Nessie could be, but here are a few, and some of them have been debunked and junked but I'll stop telling you what I think and let you decide for yourself!


 A Plesiosaur
     Plesiosaurs were marine reptiles that died out over 65 million years ago. There are two problems with this theory. One being that Lake Loch Ness is a very cold body of water(the average temperature is 5.5˚C) and an air breathing animal would have to come up for air quite frequently. Secondly if a group of plesiosaurs was there that survived there would have to be a whole population.
    In 2003, a fossilised vertebra of a plesiosaur was found on the banks of Loch Ness, but due to the local geology it was not a fossil bearing type of rock, so many people regard this as a hoax placed there by a prankster.
A Seal   
     Some people can accidentally identify things wrong that they see in the Loch Ness Lake. Several could assume it is the monster because they are at Loch Ness.It has also been said that there is a new species of seal in Loch Ness - a long-necked seal. The unfortunate reality of this is that there is no such discovered species of seal.   
Other Theories
    It has also been said that it was a circus elephant being bathed, an overgrown eel due to its lack of puberty, a sturgeon(even though they haven't been known to even breed in that country), some say a ghost, and even a tulpa(a mirage made up by people who want to believe). There are many more things that have been said and already so many that have been ruled out, so what do you think?
