“Pirana” is simply an alternative spelling of "piranha," a carnivorous freshwater fish known for its sharp teeth. They live in South American rivers. Just like the proper spelling, 'pirana' refers to a group of fish known for their strong jaws and sometimes aggressive behavior. They are often feared, although their actual danger to humans is often exaggerated. Whether you spell it 'piranha' or 'pirana,' you're talking about the same fish.
