Bigger animals are a living world for smaller ones. Animals are plagued by unwanted visitors just as much as human beings. Some bugs are simply hitching a ride, but others are definitely hungry, treating their particular host as their next meal. Find out in this book what's living on - and in - what. The "What Lives" series introduces kids aged eight-12 to the fascinating domain of bugs and insects. The books are illustrated with magnified colour pictures and scanning electron micrographs and are written in a grippingly gruesome style. Fact boxes highlight important and extraordinary buggy facts from around the world, while games and quizzes test how much knowledge readers have absorbed.
