Chester Zoo taken over by robotic 'super predators'

Thirteen enormous super predators have taken over Chester Zoo as part of a new robotic exhibition.

Spanning more than 200 million years of history, the creatures range from a 13-foot snake through to the largest shark of all time, the Megladon.

The exhibition has a serious message. It's aim is to highlight that extinction is forever.

Take a look at the video to see the mega beasts in action.
