Researchers from the University of Tokyo have discovered that two species of tree snails use a unique mechanism to change color in the rain. By absorbing water into porous shells, the snails reveal a darker layer underneath, providing dynamic camouflage against wet tree bark.
Why it matters
This biological discovery offers potential inspiration for the development of new smart materials and sensors that react to humidity without requiring external power.
