Winner: Grand Prize and Nature
An Indochinese tigress named Busaba shakes herself dry after a swim at Khao Kheow Open Zoo in Chonburi, Thailand. Titled "The Explosion!" the photo was the winning entry in the 2012 National Geographic Photo Contest.
The Indochinese tiger—found in parts of Myanmar (Burma), Thailand, Laos, Vietnam, and Cambodia—is one of six tiger subspecies, all of which are endangered or critically endangered. It's estimated that only about 350 Indochinese tigers exist in the wild.
