A DNA study of water samples from Loch Ness in the United Kingdom showed the presence of about 3000 species—including microorganisms, humans, and lots of eels—but no Loch Ness monster, The Guardian reports. The study, led by researchers at the University of Otago in Dunedin, New Zealand, is one of the largest of its kind. Researchers analyzed 250 samples of Loch Ness water from different areas in the lake and varying depths for DNA. They found every fish known to reside in the lake, the team reports, as well as a surprising amount of eel DNA. Neil Gemmell, the lead researcher on the study, hypothesized that the monster could just be an enormous eel. But even though the team found no evidence of plesiosaurs, Gemmell says, “we can’t prove a negative.”
