Magnificent Molars

The big bad wolf has nothing on marine animals when it comes to a strong set of chompers. Each of these three species of fish has a mouthful of molars. And we mean mouthful! Which wins your vote for the most magnificent molars?

Parrotfish

Parrotfish
While they can't say "Polly wanna cracker," parrotfish are quite remarkable. Their large front teeth are fused together like a parrot's beak and they use these teeth to chip away at coral reefs. A second pair of teeth is used to grind the coral down into little pieces of sand, edible algae, and coral polyps. What parrotfish don't digest, they excrete. Just one parrotfish may produce as much as a ton of sand each year. That's enough to fill a backyard several feet deep — a great source for those beautiful white sand beaches.

Sand Tiger Shark
The teeth of the sand tiger shark might not look sweet, but they're like Pez® candy. When one tooth gets worn down, another one pops into place. That's because sand tiger sharks, like all sharks, have rows of replacement teeth that move up into place when a tooth gets worn down. In just one year, a sand tiger shark may grow, use, and lose up as many as 1,000 teeth. South Africans call this shark "ragged tooth."
 
Viperfish

Viperfish
A dentist would have a hard time with a viperfish. Its teeth are too big to fit inside its mouth! These fang-like teeth are great for trapping and piercing other fish as well as crustaceans. A viperfish can open its jaw really wide and its stomach can expand to at least twice its normal size. During the day, viperfish hunt deep down in the ocean (deeper than 1,000 feet), but at night they come up to shallower waters where food is more plentiful.
