Piranha Eat Fast

We took the kids over to thePiranha Sign Denver Aquarium today, hoping to take advantage of the New Year holiday and hopefully hit no crowds. For this installment of Today I Learned, I was surprised to find out that a large school of piranha can apparently eat an entire cow in 3-4 minutes. 3. To. 4. Minutes. I’m not sure that a well coordinated pack of human beings could completely clean a carcass of a cow with proper butchering knives. I was a bit skeptical when I read this, but I did a little searching and it turns out that an account of this sort of cow-nivorous behavior (groan) was reported by none other than President Theodore Roosevelt on an expedition to Brazil. Sure, the fish has been corralled and starved for a few days, but hells bells man.
