Despite a few inconsistencies and variations, Nessie is usually described as a creature with two humps, a tail, a long, snake-like neck and a small head. The monster is reportedly 10 to 15 m (30 to 50 ft) long.
A V-shaped was often mentioned, as well as a "gaping red mouth" and horns or antennae on the top of the creature’s head. It is popularly believed to be female.
The creature glides just under the surface for a time and then submerges back into the deep.
