About Pulmonata: the wider group
Order-level background for Pulmonata, the group containing Clausilia bidentata. Species-specific details appear above.
Group overview
Pulmonata includes terrestrial and freshwater snails and slugs with ~30,000 described species. The giant African land snail (Lissachatina fulica) can reach 20cm and is one of the most invasive species globally.
Ecological role of the group
Terrestrial gastropods are important decomposers and calcium recyclers in forest ecosystems. They are also critical food sources for birds, hedgehogs, and beetles. Many species are hermaphrodites, possessing both male and female reproductive organs.
Economic and practical significance of the group
Slugs and snails cause billions in crop damage worldwide. The global molluscicide market was valued at $800 million in 2023. Conversely, edible snails (escargot) support a global industry worth over $4 billion annually.
