Snakes have developed the ultimate economy of design and are the most elegant and iconic of hunters. Among the incredible species seen here are blind tiger snakes that hunt using their sense of smell, magnificent African spitting cobras and a bizarre turtle-headed sea-snake hunting on a coral reef. And, for the first time ever, cameras capture a snake ambush in the wild and the beautiful spectacle of yellow anacondas giving birth underwater.

Argentina's northern territory contains one of the largest reserves in the country. Ibera is a vast expanse of swamps, marshes and lagoons, with a biodiversity count to rival the Pantanal. These lands are bursting with life, home to over 4000 animal and plant species. The rainy season in Ibera finds the wetlands in bloom... but unseen perils lurk beneath the surface, and even here, life can be a struggle for survival.

The final programme looks at the superorganisms formed by bees, ants and termites. Attenborough reveals that their colonies, whose individuals were once considered purely servile, are "full of conflict, power struggles and mutinies." They evolved when such creatures moved away from a solitary existence and started building nests side-by-side, which led to a collective approach to caring for their young.

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.

The journey begins on the Galapagos' west side at the youngest and most volcanically active islands in the archipelago, Isabela and Fernandina, which are home to a richly diverse wildlife scene. Here, Liz and the team journey into the clouds above Wolf, the tallest volcano in the Galapagos, where they join a group of biologists hunting for the elusive pink iguana, which teeters on the edge of extinction. But how and why did it come to live on the top of a volcano? Back on the research vessel, Liz boards Alucia's Triton submersible to descend a kilometre into the ocean abyss in search of a new species hiding in the darkness. Liz also travels to one of the most remote locations in the Galapagos, Alcedo Volcano, in search of the largest population of giant tortoises. Plagued by drought in recent months, scientists are keen to find out how this prehistoric species has fared. Finally, Liz helps out with a groundbreaking science experiment to x-ray marine iguanas that have so far stunned the scientific community with a new mutation. As with all life on these remote islands, the key to survival is adaptation.

David Attenborough examines creatures that have baffled us for centuries. This episode looks at two animals that use tools, orangutans and crows.
