The whole ridiculous plan was an attempt to get back at his employer, a newspaper called the Daily Mail that had ridiculed him in a recent issue. Wetherall had Dr. Wilson submit the picture to give it more "respectability."

So that's the end of the Loch Ness Monster, right?
Not even close. Die-hard cryptozoologists immediately dismissed Spurling's hoax confession, insisting the resources that he described being used to make the fake monster didn't exist in 1934 (fake monster heads would apparently not be invented until much later).
To this day, the Loch Ness Monster industry is thriving, and every few years there's a new, expensive expedition setting out to find it. There was a 2003 BBC special that employed satellites and 600 separate sonar beams to try to track down the beast once and for all.
So Why Do They Still Believe?
The fact that there are "cryptozoologists" in the world (that is, people who specialize in tracking legendary creatures to prove they're real) should tell you. There are people who have staked their reputations on the creature being real and depend on the income from books asserting such. It's not so easy for somebody in that position to give in to the "wooden head glued to a toy submarine" theory.
