The highest mountains on Earth are home to snow leopards, golden eagles, mountain goats, barnacle goslings, and gelada monkeys; only the toughest of animals can endure the extreme weather, scarce food supplies and limited oxygen on these peaks.
They might be young and vulnerable, but every second of these baby animals' lives is a training ground, preparing them for their destiny as an elite predator. Watch as young lions, coyotes, cheetahs, and foxes engage in the kind of play that prepares them for life at the top of the food chain.
Sharks are among the most misunderstood predators on the planet, but an international team of scientists is trying to change that. Their research is revealing that sharks can be sociable and intelligent, and they could even help solve some of the toughest medical challenges of the 21st century. However, their breakthroughs come just as many sharks face extinction. Science may now be the only way to save them.
David Attenborough narrates the story of Rodrigo Medellin. Since he first kept vampire bats in his bathroom as a child, Rodrigo has dedicated his life to saving them. Now Mexico's most famous export, tequila, is at stake. Rodrigo's beloved lesser long-nosed bat is crucial to the liquor - pollinating the plants the drink is made from. To save both, Rodrigo must track the bats' epic migration across Mexico - braving hurricanes, snakes, Mayan tombs and seas of cockroaches. The threats are very real for not only Rodrigo and the bats, but also for anyone with a taste for tequila.
