The harmless-looking silver and brown speckled piranha is the deadliest fish in the world. This blood-thirsty fish of South America’s Amazon River has jaws containing triangular-shaped teeth as sharp as razor blades. A school of these meat-eaters can strip an animal or a human being down to a skeleton in just a few minutes.

Because the piranha has a huge appetite, it will go after any bait on a fisherman’s hook. But once it is hooked and unable to free itself, the rest of the school of piranhas will strip its bones clean too.

South American natives use the piranha’s sharp teeth as tips for their arrows!
