カタツムリ, or snails, are small, slow-moving creatures known for their spiral-shaped shells. They belong to the class 腹足類 (gastropods) and are found in various environments, including gardens, forests, and near water bodies. Snails are primarily herbivores, feeding on leaves, fruits, and decaying plant matter. These mollusks have a soft body and a muscular foot that helps them glide over surfaces. They produce mucus to aid in movement and to protect their bodies from rough terrain. カタツムリ are also known for their ability to retract into their shells for safety when threatened.
