PURE WHITE TIGER AND PURE BLACK TIGER

You will, however, find tigers which are very close to being pure white, but these still have some areas of very faint striping and colour to be found on the lips, nose and paw pads; this means they are not albino animals. Though there is no reason albinism cannot occur within tigers, experts who have been consulted have all stated they have yet to sight a true albino. 


 Black tigers do not exist.


 Yes, they do! Well, they have done. We now have photographic evidence of this colouration occurring, at least in Bengals. It is a simple case of melanism. This means there is an abnormally high amount of dark pigment in the coat. It is also melanism which causes black jaguars and leopards, often termed black panthers.

A black tiger is a rare color variant of the tiger and is not a distinct speices or geographic  There subspecies are reports and one painting (now lost) of pure black non-striped tigers (true melanistic  tigers). Most black mammals are due to the non-agouti mutation. Agouti refers to the ticking of each individual hair. In certain light, the pattern still shows up because the background color is less dense than the color of the markings.


So-called black tigers are due to pseudo-melanism Pseudo-melanistic tigers have thick stripes so close together that the tawny background is barely visible between stripes. Such tigers are said to be getting more common due to imbreeding. They are also said to be smaller than normal tigers, perhaps also due to inbreeding or because large black leopards are misidentified as black tigers. A discussion of black tigers was presented by British cryptozoologist Dr Karl Shueker in his book Mystery Cats of the World.
