White Bengal tigers are distinguished by the color of their fur. White fur caused by a lack of the pigment pheomelanin, which is found in Bengal tigers with orange fur. Compared to Bengal tigers, white Bengal tigers tend to grow faster and heavier than the orange Bengal tiger. They also tend to be somewhat larger at birth and as adults. Bengal white tigers are fully grown when they are 2 to 3 years old. Male white tigers reach a weight of 200 to 230 kilograms (440 to 510 pounds) and can grow up to 3 meters (9.8 feet) long. As with all tigers, the white stripes of the Bengal tiger are like fingerprints, and no two tigers have the same pattern. Tiger stripes are a pigmentation of the skin; if a person were to shave, their distinctive coat pattern would still be visible.
