About Elimia livescens (Menke, 1830)
Elimia livescens is a species of snail originally described by Menke in 1830. For this species' shell, the maximum height can reach up to 20 mm. This snail is native to the United States. Its native range covers the Saint Lawrence River drainage, extending from the Great Lakes to Lake Champlain; tributaries of the Ohio River that lie east of the Scioto River in Ohio; and the Wabash River, reaching west as far as the Illinois River. This snail has also established a nonindigenous population in the lower Hudson River drainage. It entered the Hudson River by migrating through the Erie Canal, and the impact of this introduction remains unknown. Elimia livescens inhabits freshwater rivers and streams, where it can be found on rock shoals and gravel bars. This species has separate sexes. Females usually lay eggs in the spring. Individuals often reach sexual maturity within one year, and can live up to 5 years.
