Thanks to motion-triggered digital camera traps, scientists have a powerful tool for studying reclusive animals in remote, inaccessible areas -- and also for generating animated .gifs of gorillas scratching their stomachs. Okay, perpetually looping scratching gorillas aren't the point of camera-trap research. But they're a very fun byproduct, along with up-close-and-personal photographs of animals glimpsed in unguarded moments. The jaguar above, filmed in Peru's Manu National Park, represents the 1 millionth image gathered by camera traps belonging to the Tropical Ecology Assessment and Monitoring Network.
