White jaguars are not (generally) albino. Rather, they are leucistic.
Currently there are only two known in the world, twins living at the Aschersleben Zoo in Germany: [link]
But, of course, this lovely jag is neither of those two gorgeous furballs. This is Luca, a regular tawny spotted jaguar who lives at the Toronto Zoo (with a bit of tinkering in photoshop, of course). Although I actually did very little to his eyes... they really are that amazing blue colour!
Wavered a bit between putting this in photo manipulation or digital darkroom photograph. I wound up going with the former, even though I seem to recall that the photo manip category originally specified two or more photos needed to be used. However, I can't find that disclaimer anywhere now, so into the manip category this goes!
