David Attenborough narrates a programme which follows several thousand pioneering young penguins as they invade Boulders Beach, a busy resort in Cape Town, in an attempt to establish a new colony amid the striped umbrellas and sun loungers.

Dinosaurs may be dead and gone, but can a living reptile now help uncover secrets of the dinosaurs' lost world? Green iguanas, adorned with impressive spikes and claws, were once cast as dinosaurs in B movies. Although they are not directly descended from the dinosaurs, new research reveals that the social lives of these modern lizards may show us how the dinosaurs behaved. David Attenborough takes us deep into the jungles of Central America and reveals a chilling cast of prehistoric-looking reptiles locked into battles every bit as dramatic as those played out by the dinosaurs.

David Attenborough looks at how research has finally revealed the secret behind the remarkable sticking power of the gecko's foot. This discovery could offer truly futuristic ways of sticking objects together, and may even help NASA to explore distant planets. Including a look at the urban-dwelling tokay gecko that happily resides alongside the citizens of Bangkok as one of the few reptiles tolerated in homes.
