Andalusia is a mosaic of extreme habitats. From the deserted Almeria-region to the snowy mountaintops of the Sierra Nevada, from the dried-out ilex woodlands of the Sierra Morena to the nebulous cork oak forests near Cadiz and Granada's shrub-covered cliffs. Over the course of histories human settling and hunting had a fundamental impact on these landscapes and their fauna. But today, many of the animals found in Andalusia have found innovative survival strategies and niches that allow them to reclaim Andalusia (only in some cases with a little help of humans).

In a protected forest on the southern edge of Brazil's Amazon Rainforest, lives one of the most intelligent and agile monkeys of the New World - the white-whiskered spider monkey. Their long tails are like a 5th limb and they rarely leave the treetops for the forest floor. They are the "ambassadors" of their forest.

Meet the unlikely collaborators working to ensure mutual survival in the Kalahari Basin. Learn of an elephant clan's symbiotic link to fruiting anaboom trees, a meerkat's alliance with a feisty drongo bird, and more flora-and-fauna odd couples.

Thirst for rain alongside the animals of the Kalahari, as they endure a brutally dry year. Witness co-operation between elephant herds in their desperate search for water and meet a meerkat's strange babysitter, who helps the next generation survive.

Explore the shores of the Northern Territory and the abundant waters of the Great Barrier Reef. Face flooded roads, hungry saltwater crocs, and killer jellyfish as Lizzie investigates why so many strange, deadly creatures make this remote area home.

After the dry season lowers the waters, siblings Kimba and Maya risk crossing the river to search for their parents. They run the gauntlet of the densest populations of crocs and hippos in Africa, and face an even greater threat on the other side.

During the last few weeks of the dry season, the prides stick close to the only available water in the river. But in Luangwa, that proximity spells danger - especially when the scent of a hippo kill compels the Hollywoods to cross the river.

Feel the heat as rising temps mean that water is getting scarce. The Manzi pack must stand alongside predators to hydrate at a remaining precious water spot. Hunt with Weka's pack to feed the pups, and watch the Stork Colony thrive against all odds.

Travel to the Arctic for a peek at the brutal challenges of life in the boreal forest, then admire some stellar animal adaptations. Witness a secret reindeer superpower, navigate a rodent labyrinth of snow, and learn why moose are gourmets at heart.

In north Tanzania, towering mountains line a dramatic valley. Enriched by ancient volcanoes, its slopes provide a variety of habitats for life to thrive and its great centerpiece holds water through even the driest of times.

Simien Mountains National Park in Ethiopia is home to some of the rarest creatures on earth. Take a glimpse into life on some of the highest peaks in Africa, in the last stronghold of shaggy, grass-grazing Geladas, elusive Simien wolves and horned Walia ibex.

Cabo Pulmo, a tiny ocean community on the shores of Mexico's Sea of Cortez, is home to an extraordinary story of marine recovery. By the mid-1980s, this near-pristine coral reef was all but wiped out - decimated by reckless overfishing. That is, until those same fishermen abandoned their way of life and fought to save what Jacques Cousteau once called 'the aquarium of the world'.

At the northern edge of the Pantanal, in one of the largest tropical wetlands on Earth, is a small pond that is home to an unusual family of rodents. They are not your typical rats or squirrels - these giants are the size of sheep! And in the middle of the dry season, this group has more than a dozen babies to raise and keep safe. It is a challenge because as big as they are, these gentle giants are on the menu of lots of predators.
