Delta Hydrobe - Probythinella emarginata
The validity of the species name, emarginata, is controversial (Hershler 1996). It used to be known as "lacustris"
The delta hydrobe is a very small (<5mm long) aquatic snail. Its diminutive size and flattened apex make it readily identifiable. While most aquatic snails in Montana possess lung tissue (pulmonate snails) and get their oxygen from the air, the delta hydrobe is one of a few MT snails that have gills (prosobranch snails).
Found wide-ranging and common in the US and Canada from Montana to Maine south to Texas
