Run, Gator, Run!

摘要

alligators, crocodiles, and gharials aren't known for their easygoing nature-and they get even less friendly when you force them to run on a treadmill. But it's worth it, because watching crocodil-ians exercise might teach us how dinosaurs breathed. The problem is, when crocs aren't being ferocious predators they're lazy bastards. To get American alligators to walk the custom treadmill in his lab at Cal State San Bernardino, vertebrate physiologist Tomasz Owerkowicz has to tap the base of their tails. Otherwise they'll just lie there, and Ahe moving belt will dump them off.
