salyangoz kabuğu is the hard, protective outer shell of a salyangoz, or snail. This shell is made primarily of calcium carbonate and serves as a defense mechanism against predators and environmental hazards. The shape and size of the shell can vary significantly among different species of snails. The shell also plays a crucial role in the snail's biology, helping to retain moisture and providing a habitat for the snail. As the snail grows, it secretes new layers of shell material, allowing the shell to expand. This unique structure is not only functional but also often beautifully patterned, making it a subject of interest in both nature and art.
