Collects over fifty true stories of heroic animals rescuing people, including a pot-bellied pig, parrot, dolphin, and half-breed wolf, with current scientific research about the human-animal bond.

Describes the ways animals use color as camouflage, warn predators they're poisonous, and communicate with friends and enemies. Some animals change colors when they get hot or cold, or when they are scared, while others change color as they age. Features two-page spreads of animals from each color of the rainbow and animals in multiple color combinations.
