What are the physical features of the Loch Ness monster?

The Loch Ness Monster, often affectionately referred to as "Nessie," is commonly described as having a long, serpentine body, with a large, elongated neck and one or more humps protruding from the water. Witnesses have reported it having a small head, akin to that of a snake or a prehistoric creature, and some accounts suggest it may possess flippers or fins. Its coloration is often described as dark or grayish, blending with the loch's murky waters. Despite numerous sightings, no definitive evidence of its existence has been found.
