Yesterday I saw a Piranha movie and thought that these fish are really demonic. I don't think they exist in the real world. Does the Piranha exist in the real world? Or is it just fiction?
Yes piranhas really exist.here's a clip of some attacking another fish. http://www.youtube.com/watch?v=VZ3YIlT1ZDM
They have been known to skeletonize a cow in just a couple of minutes. The movie Piranha 3D tweaks them, but they are nasty buggers.
