I've been obsessed with aquariums and zoos since I was a kid, and the Academy of Sciences in San Francisco is incredible. So many creatures and exhibits to see, it's hard to do it all in one day. My favorite was Claude, this albino alligator. For one moment, he was basking in the ray of light that is hitting him in this photo. A second after this photo was taken, he jumped in the murky water to the right.
