Do snails and slugs have the same skin?

Snails and slugs have similar skin in that both are soft and moist, which helps them retain moisture and facilitates movement. However, snails have a hard shell that covers and protects their bodies, while slugs lack this shell, leading to differences in their skin texture and vulnerability. Both types of gastropods produce mucus to aid in locomotion and prevent desiccation, but their skin adaptations reflect their differing lifestyles.
