Payara

You know you?re a weird-looking fish if a popular nickname for you is ?vampirefish.? The two long fangs on its lower jaw make it look like one of those fish found in the deepest, darkest parts of the ocean, but they are actually native to the Amazon Basin and Orinoco River in Venezuela. Those fangs can grow to be 4-6 inches long, pretty big for a fish that rarely grow much bigger than a foot. What do they use the big teeth for? Well if one of your primary targets is a piranha, another Amazon fish famous for its teeth, youd do thankful to have some long, sharp teeth too.
