Answer:
True
Step-by-step explanation:
The zebra mussel is native to the Caspian Sea, Black Sea, and Azov Sea in western Asia and eastern Europe. They are invasive species that displaced native mussels. From the nineteenth century it spread through central Europe with river navigation and in 1985 it reached North America, the Great Lakes, from where it has spread through the Mississippi basin to the Caribbean. It is currently in a process of expansion and is colonizing freshwater in Europe, Asia and North America.
