About
Chinese Mystery Snails
Chinese mystery snails and banded mystery snails are non-native snails that have been found in numerous Wisconsin lakes. There is not a lot yet known about these species, however, it appears that they have a negative effect on native snail populations. The mystery snail's large size and hard operculum (a trap door cover which protects the soft flesh inside), and their thick hard shell make them less edible by predators such as rusty crayfish.
