The most popular theory about Nessie is considered to be the version with the ancient aquatic plesiosaur, and the theory of a huge eel is most often mentioned among modern ones. But biologist Henry Bauer has his own point of view.
Retired chemistry and biology professor Henry Bauer claims that after years of researching the elusive monster nicknamed Nessie from the Scottish lake Loch Ness, he finally understood what exactly this creature is.
According to Bauer, people have been fooled for several hundred years by large prehistoric sea turtles, a small population of which supposedly lives in Loch Ness.
These turtles, according to his theory, once accidentally got into this lake from the ocean in ancient times, when the water level here was much higher. And when the water subsided, the turtles were trapped. Over the next centuries, they have adapted well and adapted to live in local conditions.
It is known that sea turtles in our time can reach very large sizes, reaching a length of one and a half meters, and in antiquity there were also much larger specimens.
And the version that Nessie is a species of sea turtles that has survived to our times, unknown to science, seems to Bauer much more plausible than those who consider Nessie an aquatic dinosaur.
Turtles breathe air, but they spend most of their time in the water, going to land only during the breeding season (laying eggs). They can have rather long necks, and their flippers are very similar in structure to the flippers of extinct aquatic dinosaurs like the plesiosaurus or mosasaurus.
Thus, when people saw a head with a large mouth on a long neck or long leathery flippers in the water, they could only see a large turtle.
Bauer analyzed many eyewitness accounts, as well as video and photo evidence of Nessie’s existence, and came to the conclusion that the hypothesis that Nessie is a huge eel (currently the most popular) does not stand up to criticism, but the version about a large turtle is very suitable.
By the way, even critics of the existence of a mysterious monster in Loch Ness admit that the lake is very large and deep, and there are so many fish in it that it can even feed a whole group of large predators.
I think it is just sturgeon. Its the only thing that could survive in Loch Ness which is a constant 6C temp.
Reptiles can not survive in such temps. And a mammal would have to have a thick load of fat or blubber, and there would be countless air and surface breaches all day long.
Its nothing or its sturgeon who occassionally surface in 3 or more goving the illusion of a continuous serpent.
My two cents.
