Snails adapt mucus properties using calcium for diverse tasks
Cepaea nemoralis snails demonstrate remarkable versatility by producing five distinct types of mucus for various functions, including crawling, adhesion to surfaces, and defence. Scientists discovered that these snails 'tune' the properties of their mucus by secreting calcium carbonate granules. The mucus's primary building block is collagen VI. This simple yet effective mechanism allows snails to create a wide range of materials, from a slippery lubricant to a protective barrier. This natural adaptation could inspire the development of new materials in medicine and other fields.
