Perhaps the notorious film is an exaggeration, but the piranhas are really bloodthirsty, and you can see this with your own eyes while fishing! Even just as a piece of meat touches the water surface it seemingly starts "boiling" as piranhas have their dinner. These fish are so proficient that you may find all your bait gone without a single fish hooked. Just look at the protruding jaws and sharp teeth—real monsters indeed. The fish is indigenous to the Amazon Basin and is found aplenty in the pampas during the dry season from May to October. Fishing season is on, but swimming is to be avoided. If you still venture in the piranha-infested waters, at least opt for the night time, as then they are less active than in the daytime. However, if you do not fancy a personal encounter with live piranhas, you might also order a fried plate and observe the menacing jaws in delicious safety.
