Welcome to the weird and wonderful world of animal alliances, where friends are a force with which to be reckoned. Life has developed an array of unseen abilities to communicate and cooperate - glowing squirrels, snake-imitating owls and even enormous trees are among those that collaborate to find food, escape their enemies and produce the next generation.

Animals go to extraordinary lengths to secure the survival of their bloodlines. In the face of predators, famine and climatic extremes they’ve evolved mysterious abilities to protect and provide for their young. River turtles join forces to predict the future; amphibians poison their young in the name of love; and a mother elephant introduces her calf to the family while it’s still in the womb.
