invasive or introduced? any ideas I have no idea I went to the beach intertidal and found that Mussels were more diverse they inhabited all the zones I checked does that mean they are invasive?

PLease help ill give ten points thanks so much

Some species from each of those 4 groups have been introduced, but there are hundreds of species in each of those groups.
