A study of the evolution and habits of amphibians and reptiles, it is the sixth and last of Attenboroughs specialised surveys following his major trilogy that began with Life on Earth.
The series comprises five 50-minute programmes, each one followed by Under the Skin, a 10-minute section that features Attenborough interviewing the scientists whose work has led to the sequences included in the main programme. It also examines the challenges faced by the crew and reveals some of the techniques used to film the series.
The series won the 2009 BAFTA Television Award in the Specialist Factual category.
1. The Cold Blooded Truth
The first episode discusses the keys to success of reptiles and amphibians, looking at thermoregulation, parental care and the time-scales on which reptiles operate.
2. Land Invaders
The second programme explores the world of amphibians, of which there are some 6,000 known species. Attenborough visits Australia to illustrate how they became the first back-boned creatures to colonise land: the lungfish, which is capable of breathing air, and whose ancestors became the first amphibians.
3. Dragons of the Dry
The third installment takes a look at the immense diversity, social skills and displays of the lizards. While they are highly adept at camouflage, occasionally there is a need to break cover in order to ward off rivals.
4. Sophisticated Serpents
The fourth episode focuses on the most modern reptiles, the snakes, exploring how they have managed to become successful despite their elongated body shape.
5. Armoured Giants
The final programme covers the most ancient of the reptiles: the crocodiles and turtles.
