    Description: This aquatic snail has a strongly spiralled and grooved shell up to 30mm long. It is pale yellow to brown in colour. Habitat: Found in flowing and still water, including rivers, dams, ponds and reservoirs. Breeding: Females are parthenogenetic, meaning they can reproduce and produce fertile young without the aid of a male. These snails give birth to live young – the young develop in a brood pouch which can hold up to 27 embryos at a time.
