The non-marine mollusks of Montana — a part of the molluscan fauna of the state in the Northwestern United States. The non-marine mollusks of Montana consist of land snails and slugs as well as freshwater snails, freshwater mussels and freshwater clams.
Species[]
A number of species of non-marine molluscs are found in the wild in Montana.
- Gastropods
There at least 155 species of gastropods found in Montana.[1] Some of these species are exotics (not native to Montana)[2] and some species have been designated as Species of Concern.[3]
- Freshwater bivalves
