* Not a distinct subspecies: White Bengal tigers are not a separate subspecies, but rather a color variation within the Bengal tiger population. They have a recessive gene that leads to their white fur.
* No specific census: Wildlife organizations don't track white Bengal tigers specifically. They focus on total Bengal tiger populations, which are estimated to be around 2,500-3,000 individuals in the wild.
* Rarity: White Bengal tigers are very rare, with only a small percentage of the total Bengal tiger population displaying this white coloration.
Therefore, while we know they are very rare, we don't have a precise count of how many white Bengal tigers are left on Earth.
