About the Show
Swim into a month of razor sharp encounters with the world’s most feared predators in the Nat Geo Wild timeslot on Saturdays. Explore underwater caves where sharks mysteriously gather and the hidden nursery where Great Whites grow into fierce hunters.

Sharkville
The great white shark is a formidable predator. Its killing prowess is well documented and observed the world over. But what it does when it's not killing seals is a mystery. Scientist Ryan Johnson sets out on a six year study to reveal a little more of the great white's secretive life. What he finds exceeds anything anyone could have imagined. His study base: Mossel Bay, a fishing and tourist town on the Southern Coast of Africa. This is the bay that unlocks the secret of these sharks. Ryan finds that they hunt, live, rest and grow up in this bay. He uncovers one of the largest resident populations of great white sharks in the world and one of only two know nursery sites. But that's not all… Ryan's most intriguing finding is that these sharks hunt seals at night.

Secret Shark Pits
The discovery of what native Mauritian diver and keen naturalist Hugues Vitry calls “shark pits” is the origin of unanswered questions about the unusual behaviour of sharks in underground caves off the coast of Mauritius. Why do dozens of sharks aggregate in these pits? Why do they act so strangely while there? In a bid to answer these questions, Hugues teams up with shark scientist Ryan Johnson, to enter the underwater world of Mauritius and explore the mysteries of the “Shark Pits”.
