Bengal tigers are the only subspecies of tiger to have color variations. In addition to the typical orange with black stripes, Bengal tigers exhibit three alternative colorations, namely white with black stripes, golden tabby, and pure white. The most common of these variations is white tigers, animals that are white with black stripes. The white coloration is caused by a mutation affecting pigmentation, and is neither albinism nor an adaptation for snowy weather as is sometimes believed. Though possible in the wild, the coloration is extremely rare and wild white tigers have shorter lifespans as they are poorly camouflaged for the Indian jungle. Bengal tigers live in southern Asia and are endangered with fewer than 2500 left in the wild.
