No, they shed their shells regularily. that is where we get soft shell crabs from; crabs who have just shed their shells and are cooked. Like a snake shedding their skin.
Physical adaptation involves changes in an organism's physical structure or appearance to help it survive in its environment, while behavioral adaptation refers to changes in an organism's behavior or actions to improve its chances of survival. Physical adaptations can include things like camouflage or protective shells, while behavioral adaptations can include hunting strategies or migration patterns.
Defense can be both a physical and behavioral adaptation, depending on the organism and its environment. Physical adaptations include structural features like shells, spines, or camouflage that provide protection. Behavioral adaptations involve actions or strategies, such as fleeing, hiding, or group defense tactics, that help organisms avoid predation. Together, these adaptations enhance an organism's chances of survival in its ecosystem.

Snails use their structural adaptation every day. They have very hard shells so they can hide from predators and it acts as its home.
