Loch Ness Monster (Scottish)
The Loch Ness Monster affectionately known as Nessie, is a mythical creature in Scottish folklore that is said to inhabit Loch Ness in the Scottish Highlands. It is often described as large, long-necked, and with one or more humps protruding from the water. Popular interest and belief in the creature has varied since it was brought to worldwide attention in 1933.
In 1968 F. W. Holiday proposed that Nessie and other lake monsters, such as Morag, may be a large invertebrate such as a bristleworm; he cited the extinct Tullimonstrum as an example of the shape. According to Holiday, this explains the land sightings and the variable back shape; he likened it to the medieval description of dragons as "worms". Although this theory was considered by Mackal, he found it less convincing than eels, amphibians or plesiosaurs.
