Theodoxus fluviatilis is a neritid gastropod that is distributed not only in limnic habitats in Europe but also in brackish waters (e.g. along the shoreline of the Baltic Sea). Animals from brackish sites survive better in high salinities than animals from freshwater locations...

These conclusions are the first explicit confirmation of odour-gated rheotaxis as a navigational strategy in gastropods and are also...

Results indicate that a panoply of antioxidant and molecular chaperone defences may be involved during the activity–estivation cycle in this freshwater gastropod. Changes in GSH concentration were also shown...
