White tigers are a pigment variation of the Bengal tiger and can live in a wide variety of habitats across India, Bangladesh, Nepal and Bhutan including tropical forests, mangroves and grasslands. Due to its lack of pigmentation, the white tiger can have difficulty surviving outside of captivity.
Siberian tigers are also rumored to be white in rare instances, although no official confirmation exists. White tigers are not true albinos, as they only lack the functioning genes that control red and yellow pigment. An additional gene mutation can result in the absence of the white tiger's stripes, making its fur almost completely white.
