Description


Amnicola are a genus of tiny freshwater snails, typically less than half an inch (1.27 cm) long. These snails possess an operculum, a hard plate that seals their shell when they retract inside. Their shells are rounded and often as wide as they are tall, usually just a few millimeters in length. Notably, Amnicola snails can survive in warm water and low-oxygen conditions. Their shells generally exhibit a tan to light brown coloration.
Amnicola snails have high-spired shells ranging from 1/8th to 1/4 inch (4 millimeters) in height. These shells typically exhibit a brownish color with subtle shading and feature up to 8 convex whorls. The masked dusky snail relies on gills for respiration, making it dependent on dissolved oxygen in the water.




Habitat


Populations are typically found in still waters environments, but can also be commonly collected in slow-moving rivers, often on woody debris.




Food habits


Amnicola populations appear to be grazers of diatoms and other periphyton (Kesler 1981 and Cattaneo and Kalff 1986). They in turn they are preyed upon by crayfish (Lewis 2001) and sunfish (Lepomis) (Osenberg 1989 and Bronmark et al. 1992).
