Garlic Snail - Oxychilus alliarius

6-8mm - the Garlic Snail is pale, yellow-brown and glossy. It has a closely-coiled translucent shell with a very low spire and a medium umbilicus. The snail itself is characteristically dark blue-grey. When disturbed, this snail produces a secretion that smells strongly of garlic. Whilst is not possible to be certain of this species from an image alone, the garlic smell from the the specimen is a helpful feature. However Oxychilis navarricus also can produce a garlic smell, though not usually as strong. O. navarricus is larger (8-10mm) and has a black mantle that is usually obvious as a dark band just within the shell. Unless identified by a recognised expert, a photo is required.

About Pulmonata: the wider group

Order-level background for Pulmonata, the group containing Oxychilus alliarius. 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.

Recorded sources for this group: FAO, agricultural pest management, gastropod research. Imported estimates may describe particular regions or reporting periods.
