Slug Signals: What Slimy Life on Land Reveals About Evolution, Survival, and Our Deep Ancestry

Slugs are easy to overlook, but their bodies tell a remarkable story. In Slug Signals, Nora F. Mercer reveals how these soft, slimy animals move, breathe, sense the world, and survive in habitats that can seem hostile to delicate life. Readers learn what slug mucus is made of, why slime is essential to motion and moisture control, and how it can serve as armor, warning, and signal. The book also clarifies what makes a slug a slug, how slugs differ from snails, and why the line between them is more evolutionary than obvious. Written for curious general readers and science-minded nature lovers, this accessible exploration turns an ordinary garden encounter into a window on deep ancestry. By following the biology and behavior of slugs, the book shows how humble land-dwellers illuminate the ancient origins of life on land and the adaptations that made survival possible. Slug Signals offers a vivid, surprising appreciation of an animal most people think they already know.
