  1. Snail shell protection
    Snail shells provide protection through the following mechanisms1234:
    • Hard, armor-like shell: The snail's shell has a tri-layered composition, with each layer playing different roles in managing forces from predatory attacks.
    • Calcium carbonate secretion: The mantle secretes calcium carbonate and a matrix to form the shell, protecting the snail from predators and environmental conditions.
    • Periostracum: The visible layer on the shell, known as periostracum, acts as a protective layer against external forces and corrosion.

    To protect itself, the snail uses a hard, armor-like shell with a tri-layered composition. Each layer has distinct chemical and physical properties that enable them to play different roles in managing forces from predatory attacks.

    Snail shell protection
    By eating food rich in lime, the snail builds its shell which provides protection against predators. The shell provides extra pro-tection against drying out and can be closed off with a slime or lime layer during dry periods.

    Snail shell protection
    In snails with shells, the mantle secretes calcium carbonate and a matrix to form the shell, protecting the snail from predators and environmental conditions. The mantle is completely visible in slugs, which lack shells and do not serve the same protective function.

    Snail shell protection
    The layer you can see (the shell is covered by a sort-of shiny one), is the snail’s version of skin. It is known as periostracum, and it is the protective layer. It forms around the shell and protects it from external forces, such as waves and rocks, and corrosion that would otherwise negatively affect it.

    How does a snail protect itself?
    Adhered to the vent structures, the snail is vulnerable to predators such as crabs and venomous snails that can puncture or crush the scaly-foot snail. To protect itself, the snail uses a hard, armor-like shell with a tri-layered composition.

    How do vent snails protect themselves?
    Many snails can close the opening to their shell with a flat, round bit of shell called an operculum. But this snail instead protects itself with scales, a feature seen before only in long extinct species, although the vent snail itself evolved recently.

    Why are snails so successful?
    The success of snails is partly due to the evolution of the shell, a hard exoskeleton made of crystalline calcium carbonate. The shell has previously just been seen as a way to protect snails from extreme temperatures and from predators. Now we know it also offers defence against nematodes. These parasites are also incredibly numerous.

    Why do snails have a spiral design?
    However, all snail shells have a spiral design, caused by the way that land snails produce and grow their shells. The shell structure protects the snail from the environment and predators. It is made up of calcium carbonate (originating in the calcium in the food that the snail consumes) which makes it very strong.
