Brief description

New Zealand Mud snailsPotamopyrgus antipodarum (Gray, 1843) is an aquatic snail native to New Zealand. It has been introduced to Europe, North America, Australia, Iraq, Turkey and Japan. In several ecosystems it is considered invasive because it becomes highly abundant, impacting the structure and function of the invaded ecosystems. Females are parthenogenetic, meaning they can reproduce without males, so a population can be founded by a single female. Most the non-native populations are female. There can be up to six generations per year, with an average number of 230 offspring per adult per year. P. antipodarum can also tolerate desiccation for several days, which allows for rapid spread (such as by birds and fishing tools) throughout different aquatic ecosystems. In several countries, including Spain, USA and Australia, it is considered as an invasive species (CABI 2019).
