Man may be entering the Information Age, but the animal world has always had its own intricate forms of delivering the message. Hosted by David Attenborough, this film takes you to a swamp in Panama, where frogs jam to the chorus of mating calls or to Kenya, where light is the medium for the message of fireflies that pluse in perfect syncopation, and to the bottom of the sea, where obscure jellyfish link signals like small underwater UFOs. From simple insects to sophisticated dolphins, this is a celebration of exchange.
