Is a snail a native species or an invasive species?

an invasive specie is an animal that is dangerous to an ecosystem. so a snail might be an invasive specie to one ecosystem, but to another, they may be part of the ecosystem.

No that is completely wrong a invasive species is a species that came to one place from another place and it doesn't belong Dont listen to that idiot it isn't an invasive species it's from North America and so no it is not. Now theres a real answer.
