Mossy Valvata
Valvata sincera Say, 1824
Gastropods

Habitat [-]
This is a coldwater species that can live at considerable depths in high calcium large lakes in association with submerged aquatic vegetation and mud. For example, it has been dredged up in good numbers from the benthos of Lake Ontario (Hiltunen 1969). Although primarily a large lake species, it can sometimes turn up in other habiats such as rivers, creeks, and eutrophic waters.

Associated Ecological Communities [-]
  • Mesotrophic dimictic lake
    The aquatic community of a lake that is intermediate between an oligotrophic lake and a eutrophic lake. These lakes are dimictic: they have two periods of mixing or turnover (spring and fall); they are thermally stratified in the summer, and they freeze over and become inversely stratified in the winter.
  • Oligotrophic dimictic lake
    The aquatic community of a nutrient-poor lake that typically occurs in a deep, steeply-banked basin. These lakes are dimictic: they have two periods of mixing or turnover (spring and fall), they are thermally stratified in the summer, and they freeze over and become inversely stratified in the winter.
