What is a disadvantage of a snail having an exoskeleton?

Provide support and protection

Restriction of body growth

Provides external protection from predators.

A disadvantage of a snail having an exoskeleton is restriction of body growth. The snail's hard external shell cannot expand or grow as the snail's body grows, leading to constrictions and deformities. This can be particularly problematic for snails during their formative years. Additionally, the exoskeleton can also limit the snail's flexibility and mobility, making it slow and vulnerable to predators in certain situations.
