Uh-oh. Piranhas. What should you do?
It's best to cross piranha-infested waters at night, when piranhas typically rest. Swim or walk across the water quickly and quietly. Try not to awaken the piranhas.
Piranhas usually do not attack humans or large animals--unless they have died or are injured. During the dry season, however, when their food supply is scarce, piranhas can be more aggressive. When driving cattle across a river suspected of containing piranhas, farmers will sometimes sacrifice a sick or injured animal downstream before letting the herd enter the water.
