A vizcacha, close relative of the chinchilla, rests on an outcropping in Chile's Atacama Desert. These sleepy-eyed herbivores are among few species who thrive in the higher, drier regions of the Atacama. They make their living off the sparse vegetation and grasses that manage to grow in this forbidding desert.
