The Loch Ness Monster is an alleged creature, identified neither as to family or species, but claimed to inhabit Scotland's Loch Ness. The Loch Ness Monster is one of the best-known animals studied by cryptozoology. Popular belief and interest in the animal have waxed and waned over the years since the animal came to the world's attention in 1933. Evidence of its existence is largely anecdotal, with minimal, and much disputed, photographic material and sonar readings: there has not been any physical evidence (skeletal remains, capture of a live animal, definitive tissue samples or spoor) uncovered as of 2008. Local people, and later many around the world, have affectionately referred to the animal by the diminutive Nessie (Scottish Gaelic: "Niseag") since the 1950s.

Champ is the name given to a reputed lake monster supposedly living in Lake Champlain. While authorities typically regard Champ as legend, some believe it is possible such a big creature does live deep in the lake.

Like the Loch Ness Monster, Champ is generally believed to be a plesiosaur, an extinct group of aquatic reptiles. A few people believe that the animal is a Tanystropheus, leading to Champ being given an unofficial scientific name, Champtanystropheus, although this theory has received little attention by the mainstream scientific community. A recent sound recording of Champ, consisting of numerous echolocation clicks, suggests that Champ may be a freshwater whale or dolphin. However, sightings of Champ do not describe a dorsal fin.

Bigfoot, also known as Sasquatch, is a figure in North American folklore alleged to inhabit remote forests, mainly in the Pacific northwest region of the United States and the Canadian province of British Columbia. In northern Wisconsin, Lakota Indians know the creature by the name Chiye-tanka, a Lakota name for "Big Elder Brother". Bigfoot is sometimes described as a large, hairy bipedal hominoid, and some believe that this animal, or its close relatives, may be found around the world under different regional names, such as the Yeti of Tibet and Nepal, the Yeren of mainland China, and the Yowie of Australia.

Bigfoot is one of the more famous examples of cryptozoology, a subject that the scientific community classifies as pseudoscience because of unreliable eyewitness accounts, lack of scientific and physical evidence, and over-reliance on confirmation rather than refutation. Most scientific experts on the matter consider the Bigfoot legend to be a combination of folklore and hoaxes. Despite that status, Bigfoot is nevertheless a popular symbol, included as "Quatchi," one of the mascots of the 2010 Winter Olympics in Vancouver, and used to name both a provincial park and the annual Sasquatch Daze event in Harrison Hot Springs, British Columbia.

The Yeti or Abominable Snowman is an apelike animal cryptid said to inhabit the Himalaya 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. Nepalese have various names for Yeti like "Bonmanche" which means "wild man" or "Kanchanjunga rachyyas" which means "Kanchanjunga's demon."

Although the scientific community dismisses the Yeti as a fraud supported by legend and weak evidence, it remains one of the most famous creatures of cryptozoology, the study of unconfirmed animals. The Yeti can be considered a Himalayan parallel to the Sasquatch or man-beast.

This is the most astonishing evidence of Nessie as of now, all of these photos are real:

The surgeons photo was proven fake. I don't know about the other Nessie photos, and the only thing there that's real compelling is the Bigfoot video.

Yea, it was like a toy submarine with a sculpted head attached or something.
