2、Suppose you discovered an unusual animal, one not described in any present zoology book. How would you begin to identify a creature that may一or may not—exist? Or suppose you came upon an animal that scientists thought had died thousands of years ago. These are exactly the kinds of puzzling situations that crypto—zoologists deal with every day.

    Crypto comes from the Greek words kryptos, which means hidden, and zoology, the study of animals. Of course, crypto—zoologists must acquire a thorough and complete knowledge of all kinds of animals, both living and extinct, such as dinosaurs. In addition, they must be able to tell the difference between a real discovery and a case of mistaken identity.

    You may have heard of people who claim they’ve seen the Loch Ness Monster or Bigfoot. Most crypto-zoologists doubt that proof of either Nessie or Bigfoot will ever be found. But they have many discoveries of 1ess impressive creatures, like the pseudoryx, to investigate（调查）.

The pseudoryx, from the Vietnamese rain forest, looks like a goat, but it is really more closely related to the ox. The evidence for the pseudoryx was pieced together from the villagers’ collection of bones, and hides. Even though the researchers could not find an actual pseudoryx, a talented Vietnamese taxidermist was able to reconstruct a model from the parts the researchers brought to him. Scientists also analyzed the genetic material from a pseudoryx’s bones. Their analysis confirmed that the pseudoryx was certainly a unique new species, unlike any that had been identified before.

      Other crypto-zoologists are presently working to prove the existence of a small ape called the orang-pen-dek on the island of Sumatra. Still others are looking into sightings of the moa, a flightless bird which was thought to be extinct for hundreds of years.

      New types of animals are continuing to be discovered. The crypto-zoologist is constantly analyzing the facts and trying to solve the mysteries. For every mystery that is solved, a new one is likely to appear.
