When naturalist Patrick Aryee is yards away from a giant grizzly bear in the first of this series about the planet’s largest animals, you fear his presenting career is about to be cut short.

Patrick also free-dives with a sperm whale, which looks amazing, and tracks down a giant green anaconda – the planet’s largest snake.

Other animals featured include elephant seals

In between these wildlife encounters, Patrick introduces some of the giant beasts that used to roam the Earth – including a metre-wide snake, an armadillo the size of a car and a three-metre-tall ‘terror bird’ with a bone-shattering beak!

Suddenly that grizzly doesn’t look quite so scary…
