Pomacea paludosa has been assessed as Least Concern. This species has a large distribution, is a habitat generalist found in lakes and streams, and is tolerant of a variety of water quality types. This is illustrated by it being transported to different areas as a plant control measure. Even though there is no accurate abundance information avaliable, it is known to be common in artificial lakes. This species is consumed in some local regions, but there is no harvesting data avaliable.

Geographic Range [top]

Range Description:This species is found in the Florida peninsula, westward to the Suwannee and Choctawhatchee rivers, and in Cuba, Bolivia, Peru southward to the Paraguay river and into southeastern Brazil (Perera and Walls 1996, Ghesquiere 2007). It has recently spread to Hawaii (Ghesquiere 2007).

Habitat and Ecology [top]

Habitat and Ecology:This is the largest snail in Florida and Cuba, reaching a maximum size of 70 mm (Perera and Walls 1996). This species is found in swamps and artificial lakes as well as the warm waters of rivers, lakes, ponds and roadside ditches (Perera and Walls 1996, Ghesquiere 2007). It is found in creeks in Cuba and slow flowing or stagnant waters in Florida (Freshwater Mollusk Conservation Society 2004). This species is amphibious and is a critical food source for the endangered Snail Kite (Rostrhamus sociabilis) (Freshwater Mollusk Conservation Society 2004). The eggs are white and are laid on emerging stems of vegetation in clutches of 10-80 eggs, roughly 3-6 mm in diameter (Ghesquiere 2007). Young begin to appear after two weeks and due to their large size when born, they are less sensitive to habitat desiccation (Ghesquiere 2007). It is also a voracious eater and can tolerate relatively acidic water conditions (Perera and Walls 1996). This species is also thought to be an intermediate host of a nematode called the rat lungworm (Angiostrongylus cantonensis) (Perera and Walls 1996).

Use and Trade [top]

Use and Trade: This species is edible and is consumed in several local areas (Perera and Walls 1996).

Threats [top]

Major Threat(s): It is unknown whether there are any major threats to this species. However, it is likely to be undergoing localized declines in areas of urbanization, habitat degradation and alterations to the habitat regime. This species is edible and is consumed in several local areas (Perera and Walls 1996).

Conservation Actions [top]

Conservation Actions: It is unknown whether there are any conservation measures in place for this species. Further research is required to determine if there are any threats impacting this species and to gather more information on its abundance.
