The dry season is now upon the animals of the Serengeti, the toughest of times for some but a food bonanza for others. The increasing drought turns the waterhole into a death trap for the herds, but for the lions it's a gift and Kali and her cubs are finally able to enjoy life back in the heart of the pride. Jasari and his wild dog family are under siege from Zalika and her hyena clan, so they must train their pups to fight back if they are going to survive. The black-maned male lions return and kill two cubs from Zalika's clan, but this is just the start of their murderous campaign. Bakari the baboon is living in exile from the troop but spies the leader bullying his adopted baby. When a huge storm ignites a devastating fire, the wild dogs are separated from their pups and struggle to save them. When it threatens the troop, Bakari returns to save the baby. The black-maned lions attack the pride and Kali is once again forced to flee for her life. As the fire takes hold and the tinder-dry Serengeti is consumed by flames, who will survive and how will the land ever recover?

He continues his epic 650-mile journey on foot, following the annual migration of Botswana's 130,000 elephants, and faces his toughest challenge yet. Together with his guide Kane, Lev treks along the route taken by the male elephants through the immense salt pans of the Makgadikgadi, via the frontier town of Gweta, to the edge of the Okavango Delta. Along the way, he narrowly escapes being surrounded by nervous bull elephants, before enjoying the incredible experience of being up close to the same group as they drink at a waterhole.

The wildlife inhabiting the world's oceans, from the shallow seas of the tropics, where predators like the lionfish can become the prey to one of the world's oddest hunters, to the greatest depths, where a massive siphonophore, longer than a blue whale, and a gulper eel with huge jaws are captured on film using specialised vessels designed to withstand the pressure. The episode also features the mating dances of mobula rays and the symbiotic relationship between Columbus crabs and turtles.

This is the story of two tiny animals coming of age. In the wild woods of North America, a young chipmunk is gathering a vital store of nuts ahead of his first winter - in his way are ruthless rivals and giant predators. In the steaming rainforest, a young tree-shrew is forced deep into the jungle to find food. She must draw on all her intelligence and agility if she is to escape the ultimate jungle predator - a reticulated python!

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.
