Documentary following the lives of two generations of big cats during the fleeting wet season in arid Botswana. This is an intimate portrayal of lion and cheetah families pushed to the edge by nature's raw power - eight weeks' of heavy rainfall - and only those that can adapt will survive.

What happens when two of the world's most deadly and ancient predators go head to head? Drawing on spectacular UGC from around the world, and the latest scientific research, shark and croc experts Dr Mike Heithaus and Dr James Nifong unpack and analyse the evidence. With growing signs crocs and alligators are pushing far out to sea and deep in to shark territory, are clashes on the rise?

The clock starts just before sunrise - when the temperature begins to rise. It’s hard work being the world’s biggest lizard on Rinca island. Competition is so fierce he can’t afford to slow down. For the biggest male on the island, an ever- warming environment and shrinking hunting grounds threaten his survival across every hour of the day.

500 lbs of pure predator, three-inch long canines and retractable claws like switchblades. Big cats areamong the fiercest four legged beasts on the planet - capable of taking down fleet-footed antelope, two tonne elephants and even human beings.NGT takes you inside the world's biggest cats - lions and tigers - to unlock the secrets of these maximum predators. New science will deconstruct the engineering of these legendary man-eaters, revealing what they are capable of, and what they're really after.Using CGI we'll peel back the layers of these top predators. A 360° CT scan of a big cat's head and jaws, plus actual dissections, reveal new insights into their engineering, sensory systems and intelligence. Archive footage and recreation of documented attacks on humans will propel us into the science and mechanics of these big predators - revealing how they think, how they work, how they hunt, and what makes them the rulers of the landscape.Crawling through Africa, we'll stalk, capture and reveal the physique, teeth, claws and ambush tactics of big Cats. GPS tracking devices will show how much land - and prey - these predators need to survive. We'll reveal their maximum appetite (over 50 pounds of meat at one sitting) and the lions' unique 'team approach' to hunting.And we'll investigate a case in Tanzania where cats have hunted humans. We'll also reveal the newly discovered ways that big cats kill. The brutish stereotype is wrong - they kill with the pinpoint accuracy of an assasin, not the clumsiness of a butcher - and we'll compare a shock troop of lions to the lone stealth of a tiger and reveal which extreme predator truly deserves the title of 'Super Cat'.

In 2009, National Geographic Pristine Seas explored the southern Line Islands and found pristine coral reefs, thriving ecosystems teeming with sharks and huge schools of fish. But in 2015-16, an unprecedented ocean warming event killed half of the corals. The Pristine Seas team returned in 2021, hoping to see some signs of recovery. What they found instead was the most spectacular recovery of coral reefs ever witnessed.
