Understanding Snail Biology and Ecology

Snails are fascinating creatures found worldwide, known for their unique anatomy and slow movement. They have a simple structure with a body and shell, which is crucial for protection and moisture retention. Snails are invertebrates and use a muscular foot to glide. They have specialized senses, relying on smell and touch. Snails are divided into land, marine, and freshwater groups, each with unique adaptations. Historically, snails have been used for currency and dye. They play a vital role in ecosystems, serving as food for other animals and helping to clean the environment.
