Planet Earth II teaser: Baby marine iguana gets chased by a dozen racer snakes

As the country grapples with grave levels of air pollution in Delhi and the rising environmental hazards, it stands oblivious of the fact that there are dozens of biomes still left untouched by humanity. These biomes are still ruled by the Darwinian principle – Survival of the fittest.Recently, BBC released a two-minute teaser clip for its documentary series Planet Earth II which demonstrates an instance of survival of the 'quickest'. The clip shows a baby marine iguana being chased down by around half a dozen racer snakes. The narration by the legendary voice of David Attenborough perfectly captures the adrenaline rush and drama that the miraculous escape of the iguana evokes.[caption id="attachment_3094620" align="alignleft" width="380"] The iguana and the snake.

Narrated by Attenborough, it was the most expensive nature documentary produced by BBC at that time and also the first one to be filmed in High Definition.In order to take its sequel to the next level, BBC has announced that it will be its first documentary which will be produced in Ultra-High Definition, according to this Digital Spy report.While the animated Attenborough returns as the narrator of the series, the makers have also roped in celebrated music composer Hans Zimmer to produce the background score. Zimmer has composed the music for films of colossal proportions like Interstellar and Inception. Given his track record, the documentary series is all set to transcend the limitations of the foreseen and the imaginable.The sequel will not limit itself to the wild but will extend its scope to the urban areas where animals coexist with humans peacefully. However, the focus will not be on the man vs. beast conflict but on how the fauna have adapted to the urban landscape and manage to survive braving all odds.The broadcast of Planet Earth II commenced in the UK on BBC One and BBC One HD. It is slated to be broadcasted internationally on BBC Earth but the date of telecast in India remains uncertain.
