Slugs are often dismissed as mere garden pests, but they are actually surprisingly important creatureFor centuries, slugs have been dismissed as unwanted garden pests, but they actually play an important role in nature. They break down decaying plants, fungi, and organic matter, returning valuable nutrients to the soil. Their movement can also help improve soil structure and spread fungal spores, while slugs themselves provide food for birds, amphibians, mammals, and other animals. One of their most surprising features is their mucus. Scientists have discovered that slug slime contains biological compounds that help retain moisture, protect against harmful microbes, and support tissue repair. These properties have attracted interest from researchers studying potential applications in skincare and medicine. Researchers have also been inspired by the strong adhesive properties of slug mucus. By studying species such as the Dusky Arion slug, scientists have developed bio-inspired medical adhesives capable of sticking to wet tissue while remaining flexible. Such materials could potentially provide new ways to close wounds and repair internal injuries. Slugs have even contributed to our understanding of the brain. The sea slug Aplysia californica has been widely studied because its large and relatively simple neurons allow scientists to examine how learning and memories form. From supporting ecosystems to inspiring medical technology and neuroscience research, these often-overlooked creatures have proved far more valuable than their reputation suggests.
