Across the planet, animals are joining forces. They are doing so in surprising and diverse ways, whether it is to hunt, build a home, or solve complex problems. Partnerships were once thought rare in the animal kingdom, but now more and more are being discovered. Some are what we might expect from animals of the same species – elephant matriarchs helping a baby elephant, a pod of killer whales hunting as a team, or a troop of capuchin monkeys scheming together to steal a meal from a snake. What’s really astonishing is that often completely unrelated species such as the finch and the tortoise, the lizard and lions, and the raven and the wolverine become unlikely collaborators. Such teamwork involves considerable brainpower, revealing just what animals are really capable of. By teaming up, animals can achieve incredible things, becoming greater than the sum of their parts.
