The dragon in the loch

Unexplained Mysteries - The dragon in the loch: "People have always believed in and often reported seeing strange creatures unknown to zoologists. Today, such unknown animals, like the Yeti or Sasquatch are called “cryptids,” meaning simply that they are hidden or little understood, if they exist at all. Although new types of animals and plants are discovered all the time, usually the animals are insects or other small creatures, but sometimes, as with the discovery of a new species of ungulate in northern Vietnam a few years ago, they are quite large. And new species are discovered fairly regularly in the oceans, which average about three miles in depth and cover very roughly three quarters of our planet. Even large and previously unknown varieties of shark and squid are found from time to time."
