Scientists Calculate Odds That Loch Ness Monster Is a Giant 20 Ft Eel (newsweek.com)
The likelihood of the legendary Loch Ness Monster actually being a massive eel has been calculated—and it's not looking good for those who believe the cryptozoological icon is actually an elongated fish.
A preprint paper written by Floe Foxon has investigated the chances of the "eel hypothesis"—that sightings of large creatures in Loch Ness in Scotland as actually huge eels—being true.
Previous DNA studies of the lake found large levels of eel DNA, leading researchers to suggest that monster sightings might instead be large eels. According to the paper, however, the chances of finding a large eel in Loch Ness are around 1 in 50,000 for a 3.2-foot specimen, with probability of finding a specimen larger than 19.6 feet essentially zero.
