The legend of Loch Ness Monster originated in 1930s. At that time, Boulte Ram Mills, the owner of a British circus, saw the elephants in his circus swimming and bathing in Loch Ness, and immediately realized that the Loch Ness Monster recently seen by someone nearby was just the elephants in his circus.

The circus owner "plays along". Mills did not reveal the secret of "Loch Ness Monster" to the world, but used it as a way to promote the circus. 1933, he issued a reward order, announcing that anyone who caught a Loch Ness monster for his circus would receive a reward of 20,000 pounds. The Loch Ness Monster and Mills Circus became famous immediately. So the Loch Ness monster is just a deceptive trick in the original work.

But in recent ten years, the Loch Ness Monster has been regarded as a very huge eel. In April 2008, two giant eel carcasses floated on the lake. Fishermen found it, and one of them was 2 meters long. It may have been attacked by a bigger eel, which was more than 15 meters long. Some scientists believe that among thousands of moray eels, several have lost their reproductive ability during their growth. Such moray eels did not return to the ocean where they were born to lay eggs, but stayed in Loch Ness.

Because the moray eel has no natural enemies in the lake, it keeps eating every day. After decades of growth, these bare sea eels have gradually grown into huge sea eels, which is also the origin of the Loch Ness monster. In any case, all the strange events that people think can be explained by science in the end. Maybe what happened after the truth came out was just an absurd joke.
