Naturalist Steve Backshall and a team of dive experts embark on an expedition to Mexico’s Eastern Pacific. Steve joins forces with renowned shark scientist Mauricio Hoyos to dive the largest marine protected area in North America – the Revillagigedo National Park. Here, they hope to witness some of the richest marine life on the planet – whale sharks, Galapagos sharks, hammerhead sharks and giant manta rays are known to gather here in huge numbers. From the Baja Peninsula in Mexico, the team travels over 700 kilometres into the open ocean. Their goal is to dive unexplored areas of the remote volcanic island of Clarion to discover where shark pups are born. Shark populations are crashing globally as they are targeted by the illegal shark fin trade. Sharks are slow breeders – some species only have a few young at a time and they take a long time to reach maturity. When commercial fishing boats catch one shark – it’s not just one life lost – it can be a whole generation. If Steve and Mauricio can discover where shark mothers give birth, they can help protect a new generation of these ocean giants.
