  • Snail Anatomy

    Snail Anatomy

    The shell of a land snail can be very different in size and shape depending on the species. Some of them are coneshaped while others are round. However, all of them have a spiral design, caused by the way land snails produce and growth their shells. This structure protects the snail from the environment and even from predators. It is made up of calcium carbonate which makes it strong and ...

  • Do snails survive with broken shell?

    Do snails survive with broken shell?

    Answer (1 of 5): That depends. If it's a small crack, it can usually be fixed with the help of a human, or just by waiting. As long as the snail is getting enough calcium, they should be able to fix small breaks with little to no help. Here's an interesting video on the subject: how i fix a broke...
