This species is the largest freshwater gastropod native to North America. [3]

The shell is globose in shape. The whorls are wide, the spire is depressed, and the aperture is narrowly oval. [3] The shells are brown in color, and have a pattern of stripes.

The shell is 60 millimetres (2.4 in) in both length and width. [3]

The indigenous distribution of this snail is central and southern Florida, [4] Cuba and Hispaniola. [5]

The nonindigenous distribution includes northern Florida. The species has also been found in Georgia, Oahu, Hawaii (Devick 1991)[ citation needed ], Louisiana, and Oklahoma. [5]
