This document discusses several cryptozoological creatures including Bigfoot, the Loch Ness Monster, and the Chupacabra. It provides brief histories and eyewitness accounts of sightings of each creature. While cryptozoology seeks to study rumored or unknown species, it is not accepted as a science by the mainstream scientific community due to a lack of evidence and skepticism. The document outlines some skepticism of cryptozoology but also notes that species once thought mythical like the Giant Panda have later been scientifically proven.
