Explore the inhabitants of an invisible world in incredible detail with this book, which contains unexpectedly beautiful microscope imagery of the tiniest spiders and insects, bacteria and viruses. Take a gander at a pollen grain, a butterfly egg, the spore of a fungus, and a human's nerve cell in extreme close up, as well as cosmic-looking pond plankton, a tiny yet terrifying caterpillar, and the well-nigh indestructible tardigrades. Other images here clarify the workings of an insect's eye, and how a plant "breathes" through its leaves.
