They play crucial roles in ecosystems as both prey and predators, contributing to nutrient cycling and controlling populations of other organisms. Additionally, snails have been used in medical research due to their regenerative abilities and unique nervous systems, providing insights into neuroscience and biomedicine. Overall, these mollusks exhibit remarkable diversity and adaptations, making them intriguing subjects for study and observation. Nadeem, NoddyBaba,Karachi
