Invasive Marine Species


Invasive species are not native to a region, but become self-sustaining once they arrive. Generally, invasive species are introduced by human activity. The presence of invasive species often indicates changing ecosystems. Invasive marine species can sometimes be found clinging to the undersides of boats or fishing equipment, such as the lobster traps pictured above. (Photo by Thomas Dewey on Unsplash.)
