1. Fangs are just super-pointed teeth! Fangs are special long, sharp teeth (usually canine teeth) designed for grabbing, holding onto, or puncturing food.

2. Snake fangs work like doctor needles. Venomous snakes have hollow fangs with little tubes running through them. When they bite, venom squirts through the fangs directly into their prey, just like a shot from a tiny syringe!

3. Vipers have fold-up fangs. Rattlesnakes and vipers have fangs so long they can't close their mouths with them stick straight out. Instead, their fangs fold back against the roof of their mouth like a pocketknife when they aren't using them!

4. Vampire bats use fangs as razor blades. Vampire bats have sharp, leaf-shaped front fangs that make tiny, painless cuts while their prey is asleep so they can lap up blood.

5. Sharks don't have fangs. Even though sharks have tons of sharp, scary teeth, they aren't technically called fangs because they aren't specialized long canine teeth!

6. Snakes can regrow lost fangs. If a snake breaks or loses a fang while hunting, don't worry—they have extra backup fangs waiting behind the main ones that pop forward to take their place.

7. Walrus tusks are actually giant fangs. A walrus’s long white tusks are actually overgrown canine teeth! They use these giant fangs to haul their heavy bodies up onto slippery ice, break breathing holes, and fight off predators.
