Incredibly, the Pacific has one quarter of the world's water and more than 20,000 islands, many of which have never been visited by humans.

This series shows us some truly bizarre wildlife, many species of which have amazing adaptations to local environments, like the coconut-opening crabs which are only found on one island. There's also the carnivorous caterpillar which mimics a twig until it's too late for approaching prey to do anything about it.  And many other examples of evolution at work.

This series is beautifully filmed and looks at human as well as animal societies, including the island race whose rite of passage involves jumping from a jerry-built wooden platform hundreds of feet high with only a carefully-measured rope attached to an ankle to prevent impact with the ground - the inspiration for bungee jumping, but a hell of a lot more dangerous.

All the colour, beauty and drama which one might expect from a location like the South Pacific is here, with a lot of surprises along the way. The frequent glimpses into wildlife's strange adaptations to specialised environments are sometimes breathtaking. An excellent series.
