Pacu fish, cousins to the piranha and known as “frugivores,” have human-like teeth that can crack nuts and fruits.

They and many other kinds of species of fish with weird teeth are featured in “Hooked,” a new National Geographic Channel series that premieres on U.S. cable television tonight.

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.
