The Loch Ness environmental-DNA survey
In June 2018 a team led by Neil Gemmell of the University of Otago sampled water across Loch Ness for environmental DNA, looking for traces of every living thing in the loch.

The account
The results, announced in 2019, found no reptile DNA (ruling out a plesiosaur) and no sturgeon or catfish, but very large amounts of eel DNA.
The sceptical view
The team said a giant eel could not be excluded but there was no evidence for one; the survey is the strongest evidence against a large unknown animal.
