This crowded continent hides the most surprising animals in pockets of wilderness. Above Gibraltar, Europe’s only primate lives a life of kidnapping and high drama, whilst in the cemeteries of Vienna grave robbing European hamsters do battle with each other. Come nightfall, the Italian mountain villages are the hunting grounds for rarely seen wolves, whilst lynx lurk in the forests of Spain. Deep underground in Slovenia’s caves, baby dragons live for up to a hundred years. Meanwhile, on the surface the continent has been developed beyond recognition.

This episode focuses on the Jurassic period, a time when the first giant killers stalked the Earth and lurked in the seas; a time when the slightest advantage meant the difference between life and death. In North America the iconic allosaurus, an ambush hunter with a lethal bite, dominated. Not even the heavily-armoured stegosaurus was safe from this killer, and incredible evidence reveals a glimpse of a vicious battle between these two giants. Life in Jurassic oceans was no easier; in 2008, a fossil was dug out of a frozen island high in the Arctic. It was a colossal marine reptile, twice as big as most ocean predators, at 15 metres long and weighing about 45 tonnes. This was Predator X. Its skull alone was nearly twice the size of a tyrannosaurus rex's, and its bite force unmatched by anything in the Jurassic seas. The balance of power between predator and prey is a fine one, as prey continually evolves different ways to avoid predators. But for the most successful and enduring predators, the battle to survive has always been tipped in their favour.

There is an electric grid submerged deep within the Amazon River, made up of a fascinating community of fish that have technological superpowers. Biologist Will Crampton ventures into this world, one which few have ever seen, on a mission to find, catch, and study electric fish. Armed with his own electric devices, join him as he uncovers the fighting style of the jaw lockers, the navigational skills of the knifefish, and the remarkable hunting technique of the electric eel.

Fish dominate the planet's waters through their astonishing variety of shape and behaviour. The beautiful weedy sea dragon looks like a creature from a fairytale, and the male protects their eggs by carrying them on his tail for months. The sarcastic fringehead, meanwhile, appears to turn its head inside out when it fights. Slow-motion cameras show the flying fish gliding through the air like a flock of birds and capture the world's fastest swimmer, the sailfish, plucking sardines from a shoal at 70 mph. And the tiny Hawaiian goby undertakes one of nature's most daunting journeys, climbing a massive waterfall to find safe pools for breeding.

120 metres down off the wild coast of South Africa lives an animal once thought to have been extinct for 65 million years - the coelacanth, locally known as Gombessa. A dinosaur fish, a living fossil, that remains the only link connecting fish to terrestrial tetrapods: its fins contain the beginning of reptile and mammal leg bones! And what about the vestigial lung found at the back of its huge mouth? …
