Among the likely creatures to have laid it are species of mosasaurs and plesiosaurs.

It was said to be a sort of plesiosaur, somehow stranded in the loch from 65m years ago.

With a long neck and flippers, a plesiosaur could reach 15 meters in length which would actually match estimations of the sheer size of Nessie.

蛇有着长长脖子和脚蹼，一只蛇可以达到15米之长，蛇长度事实上可以与尼斯湖水怪净长相匹配。
