Abstract: Pomacea canaliculata, the only freshwater snail among the 100 worst invasive alien species listed by the World Conservation Union, has caused incalculable agricultural and ecological harms worldwide. Owing to its wide habitat adaptability, strong adverse resistance, high reproduction rate and abundant genetic diversity, P. canaliculata can establish wild populations rapidly in new habitats, especially in some dissimilation and fragmentation environments. Defense abilities of P. canaliculata to natural enemies, bacteria and parasites are other effective ways to maintain its survival and reproduction. Declining biodiversity caused by P. canaliculata invasion can generate a vicious circle and further enhance the invasive incidence. In this paper, invasion mechanisms of ecological tolerance, population genetic variation and reproductive growth, defense and competition capacity of P. canaliculata with native species, ecological vulnerability of invaded habitats were reviewed and summarized. Some relevant research perspectives were also put forward, with an attempt to provide basic information and references for prevention and controlling of P. canaliculata invasion.
