This is a picture of a Polar Bear sticking his tongue out (not at me, I hope!) from the San Francisco Zoo a little bit ago. A couple of things about this picture stand out to me:

1. The color of the Polar Bear’s tongue is kind of mottled.

2. The skin of the Polar Bear is actually not quite as white as I would have expected. While I assume this to be an issue of the living conditions in a zoo, I think many people think the fur is going to be as white as snow.
