Loch Ness monster might just be a giant eel, says study

Scotland’s fabled Loch Ness monster could possibly be a giant eel, scientists said on Thursday after an intensive analysis of traces of DNA in the Loch’s icy waters. The results ruled out the presence of large animals such as dinosaurs, they said.

But there was a lot of eel DNA in the Loch, Neil Gemmell, a geneticist from New Zealand’s University of Otago, told reporters.

“Eels are very plentiful in the loch system — every single sampling site that we went to pretty much had eels and the sheer volume of it was a bit of a surprise,” Mr. Gemmell said.

“We can’t exclude the possibility that there’s a giant eel in Loch Ness but we don’t know whether these samples we’ve collected are from a giant beast or just an ordinary one.”

Mr. Gemmell noted however that despite the idea of a giant eel having been around for decades, nobody had ever caught a giant one in the Loch.

The international team of scientists took their samples of so-called environmental DNA (eDNA) in June last year.

The use of eDNA sampling is already well established as a tool for monitoring marine life like whales and sharks. Whenever a creature moves through its environment, it leaves behind tiny fragments of DNA from skin, scales, feathers, fur, faeces and urine.

This DNA can be captured, sequenced and then used to identify that creature by comparing the sequence obtained to large databases of known genetic sequences from hundreds of thousands of different organisms.

The most famous picture of Nessie was taken in 1934 and showed a head on a long neck emerging from the water. The photograph was revealed 60 years later to have been a hoax that used a sea monster model attached to a toy submarine.
