Catching Flies

Archerfish and baseball outfielders appear to use different strategies to snag a projectile.

Archerfish (Toxotes jaculatrix) are famous for their unusual way of hunting insect prey. Upon spying an insect on a twig or a piece of foliage hanging above the water surface, the fish shoots it down using a strong, accurately aimed jet of water. Once dislodged by a shot, the insect tumbles down, following a roughly parabolic path.
