In a race to find out what great pressures confront life in our ocean, the team continue their mission to investigate the effect human impact has had on our marine ecosystem.
The penultimate instalment investigates the primates, whose defining characteristics are forward-facing eyes for judging distance, and gripping hands with which to grasp branches, manipulate food and groom one another. The programme begins in Madagascar, home to the lemurs, of which there are some 20 different types. Two examples are the sifaka, which is a specialised jumper, and the indri, which has a well-developed voice. Away from Madagascar, the only lemur relatives to have survived are nocturnal, such as the bushbaby, the potto and the loris. The others were supplanted by the monkeys and a primitive species that still exists is the smallest, the marmoset. However, Attenborough selects the squirrel monkey as being typical of the group. Howler monkeys demonstrate why they are so named their chorus is said to the loudest of any mammal and their prehensile tails illustrate their agility.

Hybrids can be bizarre and they can be deadly. We look at two hybrid animals that owe their existence to human interference - the pizzly bear (a cross between a polar bear and grizzly), which has come into being because of global warming, and the killer bee, brought into existence because of the transfer of African bees to South America.

In the heart of the Atlantic, Gordon Buchanan joins a team looking to discover why huge numbers of devil rays, fish with 'wings' nearly four metres across, and gather every summer near the Azores archipelago. In northeast Turkey the on-board cameras are carried by brown bears as part of a study trying to understand why so many bears survive in a small patch of forest. In southern France on-board cameras help scientists trying to prove that guard dogs can help protect sheep flocks from wolf attacks. The night-vision cameras show how the dogs work together as a team to fend off the wolves.

The Rockies are the spine of North America, a beautiful wilderness of snow-capped peaks and hidden valleys. Cougars hunt in abandoned ranches, wolverines search the deep snow for food and grizzly bears hunt in the high mountain meadows. Daredevil wingsuit flier’s leap from mile-high cliffs and Native American tribes compete in breakneck horse races. It is also the range of surprises, with tiny cannibal salamanders hunting in mountain ponds and hummingbirds making enormous migrations

Under the waves and tropical sun, each of Hawaii’s volcanic islands host a unique ocean landscape teeming with biodiversity. But one predator reigns supreme – the shark. With 40 species of shark calling these warm waters home, scientists are seeing new animal behavior around every corner. Whitetip reef sharks “sleep” in tight volcanic tunnels. In the deep water, everything is on the menu for the hunting Tiger shark, from birds to Humpback whales. Hopping from island to island, uncover surprising moments of cooperation, rarely seen hunting tactics and striking insights into these predators of the world’s paradise.
