The snail that lost its' shell

- The time has come to start showing the snails that have evolved, abandoning their shell in their adult life. A hard cover protects from hungry predators, but these cute creatures evolved spectacular camouflage or chemical warfare for protection. This particular slug was frightened by me so it retracted its' rhinophores-sensory organs and gills (hole in the back of the picture). They can vary greatly in color within the Med, depending on what sponge they feast upon! They are common in Greece so keep your eye out!
