A snail is a small, slow-moving creature with a soft body and a coiled shell on its back. It belongs to the mollusk family and is known for its characteristic slime trail that it leaves behind as it crawls along the ground. Snails are typically found in gardens, forests, and other moist habitats, where they feed on plants and decaying matter. They have a unique ability to retract their bodies into their shells for protection. Snails play important roles in ecosystems as decomposers and serve as a food source for various animals.
