Although an archerfish's main diet consists of worms, shrimp and other small animals, the 9-inch swimmer is also able to shoot insects off overhanging foliage with a forceful stream of water droplets. In this way the keen-eyed fish is actually more like a repeating BB gun than a bow and arrow. To minimize the effects of refraction and maximize the odds of a bull's-eye, the great striped hunter positions itself directly under its unsuspecting prey and flicks its unique tongue, sending water jets as high as 5 feet. If it misses the target, the determined fish will usually reload and re-aim. Sometimes, however, it forgoes the ammo and instead leaps from the water to snag its dinner with sure-fire jaws.
Grebes also eat their own feathers, and even feed feathers to their newborns.
In the stomach the feathers break down into a feltlike ball, leading to speculation that the practice is protection against the sharp fish bones. Or maybe they just taste good. Enter your choice and then go to the podium for the medal ceremony.
