What is a "snail"?

A snail is a small, soft-bodied creature that belongs to the mollusk family. They have a spiral-shaped shell on their back, which provides protection and serves as their home. Snails are commonly found in diverse habitats, including gardens, forests, and aquatic environments. They move slowly by gliding on a muscular foot and leaving a trail of slime behind them. Snails are herbivorous and feed on plants, algae, and decaying matter. They play an important role in ecosystems as decomposers and as a food source for various organisms. Snails are known for their ability to retract their bodies into their shells when threatened. With their unique appearance and gentle movements, snails have fascinated both children and adults alike.
