The Loch Ness Monster is alleged to be a creature inhabiting Loch Ness in Scotland. Popular interest and belief in the animal has fluctuated since it was brought to the world's attention in 1933. Evidence of its existence is largely anecdotal, with minimal and much disputed photographic material and sonar readings. The scientific community regards the Loch Ness Monster as a modern-day myth, and explains sightings as a mix of hoaxes and wishful thinking. Despite this, it remains one of the most famous examples of cryptozoology. The legendary monster has been affectionately referred to by the diminutive Nessie (Scottish Gaelic: Niseag) since the 1950s.

Bigfoot, also known as Sasquatch, is an alleged ape-like creature purportedly inhabiting forests, mainly in the Pacific Northwest region of North America. Bigfoot is usually described as a large, hairy, bipedal humanoid. Many believers in its existence contend that the same or similar creatures are found around the world under different regional names, most prominently the Yeti of the Himalayas.

The Yeti or Abominable Snowman is an apelike cryptid said to inhabit the Himalayan region of Nepal and Tibet. The names Yeti and Meh-Teh are commonly used by the people indigenous to the region, and are part of their history and mythology. Stories of the Yeti first emerged as a facet of Western popular culture in the late 1800s.
