It's Shark Week and we're diving to the depths of the blue planet to take a closer look at one of nature's most fascinating and fearsome predators.
Did you know there are over 500 species of sharks living today or that this unique fish evolved around 420 million years ago?
Did you know that sharks are the apex predator in every ocean ecosystem worldwide or that over half of all shark species live in the deep ocean, below 660 feet (200 m)?
You likely know that whale sharks are the largest known fish on earth, but did you also know that many species of sharks are endangered? This is largely due to human activity, as nearly 100 million sharks are killed annually for human consumption.
In his fascinating text on shark behaviour, Sharks: Ancient Predators in a Modern Sea, leading shark research scientist Salvador Jorgensen invites readers to explore the undersea world of sharks in every ocean.
To get you started, we've created a shark-spotting map of where many different species of shark call home. Check it out below, and head to our Facebook page to enter our Shark Week giveaway. You're gonna need a bigger bookshelf...
