Summary:

A look at some of the planet's great gatherings, creatures that come together in inconceivable numbers, sometimes in millions, billions, and even trillions. Some gather to breed, migrate, for protection, or simply to keep warm. But in the process, a kind of super-organism is created in which individual intelligence is superseded by a collective consciousness that shares information and moves with a single purpose for the benefit of all.
