Pacu fish, cousins to the piranha and known as "frugivores," have human-like teeth that can crack nuts and fruits.
Also known as the "Vampire Fish," The Payara earns its "vampire" nickname with a set of two-inch daggers thrusting up from its bottom jaw.

Vampire fish, having 2 different sets of teeth, one that has human looking teeth and one that has reptilian snake looking teeth. Why did evolution spit out these fish and their funky teeth?! It will be interesting to see what attributes it has in a few million years!
