Piranhas Smell Blood And Go On Feeding Frenzy And It's Caught On Film

They keep coming and coming.

We know piranhas have a scary reputation, but seeing them up close is a whole other story. We're glad there was a computer screen between us and them. 

Nice chompers. Yikes.

To be fair, out of the few documented cases of humans being eaten by piranha schools, it did occasionally occur after the person had already died in the water, either by drowning or heart failure.

A piranha bite is most often a defensive act as a means to protect their school. And even then, according to recent data, the victim is usually bitten on the feet. (Did we say just?)

So now that we know they're not "out to get us," as long as we don't bother them, we'll be fine right? Um, not so fast. 

One study indicated that bites were associated with high density of piranha in the dry season when the water level is lower, high density of swimmers, and disruptions in the water such as splashing or food spillage. 

So, you'd still want to be careful the next time you take a swim in the Amazon. 


According to Smithsonian Magazine, piranhas can pick up the scent of a single drop of blood in 200 liters of water.

Well, then, it's no surprise to see them go on a feeding frenzy when raw meat is thrown into a Brazilian river. 


They get wilder and wilder.

Poor, misunderstood piranha. Still, we wouldn't want to stick our toes in there.
