The Loch Ness Monster could actually be a whale's penis.
Professor Michael Sweet has suggested that people have previously confused a whale's private parts for the mysterious creature during mating sessions.
Sweet claims that travellers used to draw what they had witnessed at sea but the interpretations may not have been accurate.
The professor took to Twitter to explain his outlandish claims.
He told his thousands of followers: "Back in (the) day, travellers/explorers would draw what they saw.
"This is where many sea monster stories ie. tentacled and alienesque appendages emerging from the water - giving belief to something more sinister lurking beneath... however, many cases it was just whale d****.
"Whales often mate in groups so while one male is busy with the female the other male just pops his d*** out of the water while swimming around waiting his turn. Everyone's gotta have a bit of fun, right?"
