Wildlife photographer Steve Winter and cameraman Bertie Gregory capture the lives of jaguars in the Pantanal of Brazil; a mother jaguar teaches her cub how to survive, while a male jaguar dives headfirst into a river to tackle a six-foot-long caiman.

Scientists dive deep on the mysterious and unusual predatory behavior of orcas attacking great white sharks, and the disappearance of the other sharks after these attacks.

Takes viewers into the center of five animal families - lions, jackals, cheetahs, hyenas and meerkats - as they raise their young in the wilderness. Innovative camera techniques are used to follow the animals' tender, emotional and often stressful stories from the moment their babies are born through different stages in their maturity.
