The Loch Ness Monster could actually be a huge catfish.
Nessie hunter Steve Feltham claims that the legendary Scottish beast could be from the giant wels species, imported by aristocrats in the 19th century for sports fishing.
They are the largest freshwater fish in Europe and are said to be able to live for up to 100 years.
The first photo of the Loch Ness Monster was taken 90 years ago, although there have been apparent sightings of the beast since the 7th century.
Feltham - who has spent three decades searching for the monster - told Saga Magazine of the wels: "They fit the description. If introduced in Victorian times, they would have been coming to maturity in the 1930s. The population would now be dwindling, which explains fewer sightings."
