7 Sets Of Teeth That An Orthodontist Would Love
The time for plastic vampire teeth is over. When it comes to spine-tingling smiles, these guys have you beat by a million.
1. Dragonfish
If you live shrouded in eternal darkness at the pitch black bottom of the sea, why not grow an extra set of teeth ... on your tongue?
2. Tufted Deer
Why anyone would name a deer with fangs after a tuft on its head is a mystery. The fangs are present only in males, who use them how most deer use antlers - to fight over mates.
3. Babirusa
Male babirusas use their huge tusks not as weapons, but as shields to protect their eyes during fights. Their tusks grow continuously, and without enough wear, can curve around and pierce the animal's skull.
4. The Northern Snakehead
These aggressive, highly invasive carnivorous fish not only have razor sharp teeth - they can move snakelike across land, and can live outside of bodies of water for several days at a time.

5. Sheepshead Fish
This beautiful fish has a set of strange human-looking teeth, with distinct molars and incisors. It only gets more interesting from there - the sheepshead is hermaphroditic, and can transition either from male to female or the other way round - or, they can be gonochorists, or unisexual.
6. Crabeater Seal
Don't let the name fool you, these Antarctic seals don't eat crab at all - they eat krill. Their pointed teeth actually branch out, creating a sieve-like structure that can filter for krill.
Crabeater seal teeth are shaped like this:
7. Vampire Fish
You know everything you hear about piranhas? Vampire fish eats piranhas for breakfast. Literally.
