Slug Slime Secrets
Slugs are soft, sticky, and slimy,. For those traits, they often get a bad reputation. But that slime that is associated with slugs is actually a remarkable liquid crystal (somewhere between a liquid and a solid, both lubricating and adhesive.) Why slime? What is its purpose? Try to take a guess…… A) Slime plays a crucial role in the slug’s mobility, increasing traction and allowing it to stick to vertical surfaces. The correct answer: ALL OF THEM! Their magic mucous consists of mucin proteins that form chains. Sugar molecules decorate the sides in repeating patterns, helping link the mucus together. The additional 96 percent of the substance is water. The slug does not waste any of its own water though, it has a novel adaptation where it dispenses dry granules of mucus which then absorb surrounding water from the environment. The granules can absorb several hundred times its water. Love slugs, or hate slugs, these fascinating creatures are exquisitely adapted and play an extremely important role in their ecosystems.
