This book introduces children to the six groups of life forms ("Kingdoms") that scientists have defined as anything that grows, reproduces, and eats: Archaea, Bacteria, Protists, Animals, Plants, and Fungi. Illustrated in Allen-Fletcher's inimitable, bright, style, it is a journey through all life forms as we know them, from bacteria that are invisible to the naked eye, to mold and mushrooms (Fungi), and to the animals that thrive in all manner of conditions. "Our world is full of wonders, but there is so much left to discover. We know more about the moon than he deepest parts of our oceans. Every year, more and more incredible discoveries are made. What will we discover next?"
