Most people find slugs gross—but these slimy creatures play surprisingly important roles in nature, science, and even skincare. In the wild, slugs act as nature’s cleanup crew. They feed on decaying plants and fungi, helping recycle nutrients back into the soil. This improves soil health and supports plant growth. They’re also a key food source for birds, frogs, toads, hedgehogs, and beetles.
Without slugs, many species would lose a vital link in the food chain. Their slime, though often seen as a nuisance, contains antibacterial and tissue-healing properties. It’s being studied for wound care and used in beauty products thanks to its hydrating, anti-aging effects—similar to snail mucin.
Even scientists have turned to slugs. Their simple nervous systems make them ideal for studying memory and brain function, helping researchers understand Alzheimer’s and neural regeneration. So next time you spot one, think twice—slugs may be slow and slimy, but they’re doing remarkable work for the planet and even for us.
