Witness the planet's most teeth-chattering fang-bearing creatures. See how millions of years of evolution have produced a variety of weird and wonderful canine contraptions used to do much more than simply chew. We'll span the globe and showcase beasts with choppers that can crush bone, dagger-like tusks that can fight off the competition, a beak that can snap off your finger, and the monster fangs that rule them all: two-inch-long hypodermic needles that carry a lethal dose of poison.
