Theories: What kind of animal is Nessie?

Perhaps the most exciting theory is the one that tells us that the Loch Ness monster is in fact a kind of dinosaur.

When the food chain of the loch was analyzed, it was estimated that the amount of salmon would not be enough to feed such an animal, and, if we take into account that the soil is poor as regards vegetation due to the pit, such a big animal would not have enough food to survive. Due to what has been explained, this theory is no longer valid.

Is Nessie an eel?
