About This Quiz

Everyone has a favorite shark. As a matter of fact, there are so many different species of shark that it's impossible not to pick the one you find most interesting. Consider the fact that there are around 500 species of these crazy creatures (and not all of them have sharp teeth!). While we may all be able to identify the great white or the hammerhead, the multitude of shark species gives us pause to consider what we really know about sharks. Sure, you probably watch Shark Week religiously every year to find out new things and learn about different shark attacks, but would you be able to tell the difference between a tiger shark and a thresher shark? If you can, you might be a shark genius, but there really is only one way to figure out your shark IQ ... and that's by taking this quiz.

We're going to ask you some of the tougher questions about what makes a shark a shark, how to spot one if you're swimming in the shallows and where you can find some of the more well-known (and not-so-well-known) species. Do you have what it takes to swim with the sharks? Take this impossible shark quiz to find out.
