Shark Facts

Whether you need info for a school project or are simply intrigued by this amazing and beautiful creature, this page has some pretty cool facts about sharks that you probably haven’t heard before. Sharks are one of the most misunderstood.


Bite Me! On second thought… Please Don’t!

After you wake up, brushing your teeth might be at the top of your list of things to do. Well, here are a few facts about shark teeth to go with your toothpaste! While you’re brushing in the hopes of keeping your teeth healthy and strong, sharks are continuously growing new rows of triangular teeth that need no jawbone to keep them in place. They are entrenched in the flesh.

Several rows of these teeth are patiently killing time (and whatever else they choose to kill) behind the current row of teeth. A sharks main row of teeth is usually replaced in a mere 8 days! Absolutely no brushing required! The ocean floor is literally covered with millions and millions of shark teeth.

Growing Teeth Forever – A Tooth Fairy’s Dream!!

A typical shark will grow (and lose) thousands of new teeth over the course of its life. So the question is, would you brush your teeth nearly as often if you were going to have 30,000 of them over the duration of your human life? Well that’s about how many a shark will have. So needless to say, he or she is not concerned with the ones left behind, or insomeone’s behind for that matter!

So the next time someone calls you big mouth, think about a shark’s mouth and its ability to hold 300 rows of teeth with hundreds of teeth in each row, then look at them knowing they are fortunate that your mouth is actually quite small compared to a shark.

Busting The Myth About Violent Sharks

It’s the shark’s reputation for being deadly that you’ve probably heard most about. Although we’ve just covered the 30,000 reasons why they can kill you, you might be surprised to discover humans are not part of the sharks diet and they aren’t quite as scary as you may think.


Humans Taste Awful!

Yap, sharks simply don’t like the taste of us. We’re about as untasty as they come. When you think about it, this makes perfect sense. Humans are rarely, if ever, completely devoured by a shark. Seeing how sharks only use their teeth to bite into their prey enough to swallow it down (mostly whole), there must be something else that happens when they bite a human and leave them uneaten. Are they aggressive? Are they protecting their space? Usually, the reason a shark will bit is simply out of mistaken identity or curiosity.


Sharks Are Curious And Intelligent Animals

You see, sharks use a process similar to a human toddler. If they bite into something and if don’t like it, they spew it out of their mouths. They also like to test things with their mouths. If they see something they’ve never seen before, they may “test bite” the object to see if it’s a food source. Many human legs are also mistaken for other animals like seals which are a part of the sharks diet. Once the shark bites and discovers it’s not the tasty treat he thought it would be, the shark will go elsewhere. Unfortunately for the human, the damage has already been done!


How Often Are Humans Hurt By Sharks?

Most attacks on humans are provoked attacks, usually when a shark bites a fisherman. Each year, there are less than 100 shark attacks on humans across the globe and most of those are not fatal. In fact, on average, there are an average of 4.2 fatal shark attacks on humans every year, worldwide.




Sharks Have Been Around For A Very Long Time!

Though many have affirmed a shark’s life expectancy to be up to 25 years, scientists have discovered that the Great White Shark and Spiny Dogfish can live over 100 years. This comes as no surprise since they have a naturally high amount of Vitamin A, but also because they have been around for more than 300 million years! That’s right, sharks have been around since before dinosaurs even roamed the earth. Pretty remarkable, right!? The history of sharks is still shrouded in much mystery, but if you want to learn more, check out our page on the evolution of sharks.

A noted difference between sharks now and those of ancient times is what is known as aprotrusile jaw. Maybe prey in the old (very old) days weren’t as tough as they have become, this protrusile jaw is what gives modern-day sharks their extremely powerful bite.
