On Earth we are bombarded with information in the form of light, sound and electro-magnetic waves. The human senses filter most of this information out, and we experience life through five narrow windows on the world with the curtains barely open. Animals also use their senses to perceive their surroundings, but are receptive to a selection of information different from that of humans: dogs, for instance, have a sense of smell many times greater than our own, and goldfish can see the beam of light from a TV remote control. Linked to a six-part television series, the illustrations and text of this book are interwoven to reveal the remarkable perceptions and senses used by animals to gauge the world around them.
