Global Range: (>2,500,000 square km (greater than 1,000,000 square miles)) Although native to southeast Asia, this common, nuisance species has been introduced widely around the world and occurs in nearly every U.S. state (Clench and Fuller, 1965) and in Canada in British Columbia, Ontario, Quebec, and Nova Scotia (Therriault and Kott, 2003).

Habitat Type: Freshwater

Non-Migrant: No. All populations of this species make significant seasonal migrations.

Locally Migrant: No. No populations of this species make local extended movements (generally less than 200 km) at particular times of the year (e.g., to breeding or wintering grounds, to hibernation sites).

Locally Migrant: No. No populations of this species make annual migrations of over 200 km.

Note: For many non-migratory species, occurrences are roughly equivalent to populations.

Estimated Number of Occurrences: > 300

Comments: In Pennsylvania, it occurs in the Delaware, Ohio and Susquehanna basins (Evans and Ray, 2010- 7 sites). In the Cuyahoga Valley National Park (between Cleveland and Akron, Ohio), this species was recently found to be the most common prosobranch in the park occurring in large numbers in five of the largest lentic environments (Indigo Lake, Kendall Lake, Woodlake, Horseshoe Lake, Sylvan Pond) (Smith et al., 2002). It was recently collected in four sites in the northern third of Indiana for the first time in the Tippecanoe and St. Josephs drainages (Pyron et al., 2008). It has been found to be commonly introduced to Minnesota in the Mississippi River headwaters and St. Croix River systems (concentrated in the Prairie River and Kettle River systems) (Bury et al., 2007). It has spread across Canada, becoming well established in several locations in southern Ontario (Therriault and Kott, 2003).

>1,000,000 individuals

This species births fully developed juveniles where, in brooding adults, all stages of development occur simultaneously in utero, from newly fertilized ova to large (5 mm), fully shelled juveniles. Prezant et al. (2006) found that water-borne cues from a predatory crayfish (Orconectes llimosus) induced a doubling of the number of offspring released and these newly born snails were generally smaller, though more variable in size, and possessed a greater shell organic content than control individuals (likely response to the predator).

The following is a representative barcode sequence, the centroid of all available sequences for this species.

There are 3 barcode sequences available from BOLD and GenBank.  Below is a sequence of the barcode region Cytochrome oxidase subunit 1 (COI or COX1) from a member of the species.  See the BOLD taxonomy browser for more complete information about this specimen and other sequences.
