"Rats and cockroaches are definitely two of the grossest animals around. They spread disease and unfortunately flock to wherever people are living. Readers of this spine-tingling volume with vivid photographs are encouraged to decide what would happen if these two pests did battle. They'll be entertained by facts about how the creatures match up in speed, intelligence, and toughness. For example, a cockroach can move around for weeks without its head! Important science concepts such as adaptations and habitats are discussed on each informative and entertaining page"--Provided by the publisher.
