BBC’s Elizabeth White talks about Emmy Award-winning series Frozen Planet

A snake slithers out of the rocks in Galapagos Island. A baby iguana, which has to cross the snake, stands still. “A snake’s eyes aren’t very good. But they can detect movement,” Sir David Attenborough’s commentary informs us. The snake is too close. The hatchling does well to remain still. But once the snake comes in contact with its tail, the iguana takes off. Sensing violent movement, several snakes slither out of the rocks. Three of them manage to catch and try to constrict the iguana. Just when you think it is all over for the iguana, it slips away, sprints, jumps, evades a snake-bite by a few centimetres and gets to safety. Just a few days after birth, it escapes death.
