Melanoides tuberculata is most likely native to Africa. It is
invasive in all other parts of the world that have water warm enough
(including hot springs and power plant thermal effluent as well as
climatically expected areas) and people who release stuff from
aquaria. It can eliminate native snail species from habitats
(including not only schistosomiasis hosts but also innocuous species)
and can carry flukes that parasitize fish.
