Pomella is a genus of freshwater snails, aquatic gastropod mollusks in the family Ampullariidae, the apple snails.
As is the case in some other genera of apple snails, Pomella deposits eggs above the waterline in calcareous clutches. This protects the eggs against predation by fish and other aquatic inhabitants.
Species Species within the genus Pomella include: Pomella americanista (Ihering, 1919) Pomella megastoma (G. B. Sowerby I, 1825)
Uruguay The name of the country Uruguay perhaps ultimately comes from P. megastoma, or in the Guaraní language. The name of the Uruguay River, which gave its name to the country, comes from the Spanish settlers' rendering of the native name the inhabitants of the region used to designate it. This interpretation is considered possible because uruguás are abundant in the riverEl País newspaper: Presentan tesis del nombre Uruguay , Retrieved 21 November 2014.
