Cryptozoology - one of the most interesting areas of modern biology. Representatives of the non-academic (yet) a scientific discipline are searching for non-existent and mythical animals, including those that are thought to be extinct. Tigers blue color - one of the most popular legends of this kind: according to some sources, these animals have seen in China nearly a century ago.
Blue or Maltese, tigers have attracted the world's attention in 1910 when one of the missionaries, traveling to the Chinese province of Fujian, noticed unusual animal blue to black stripes. First, the traveler thought it was a man in the blue striped dress, but coming closer, surprised to realize that the tiger in front of him, only wool bluish tint.
Missionary did not believe the story, so he announced the reward for the capture of the animal. Many experienced hunters tempted by big money, took part in the search, but out on the trail of a unique predator could not - the word missionary and left nothing the confirmed "Bike».
After the incident with missionary information about these animals occasionally come from different corners of the globe. For example, many have reported birth blue tiger cub at the zoo Oklahoma in 1964, but the photos, imposed as an "evidence", one can not say what color was the cub, which, by the way, soon after birth, expelled their mother. < br />
Although it is documented the existence of the Maltese tigers have been recorded, cryptozoologists suggest that may cause blue wool tigers. In theory, this phenomenon may be due to a deviation in the agouti gene, which is responsible for striped color present in many cats, dogs and other animals. In some cases (usually in domestic cats), there has been a violation of the production of the pigment pheomelanin, whereby instead of yellow and orange color coat has a bluish color.
