What is invading Maine's coastal waters? The Asian shore crab (1), Dead man's fingers (2), Bonamia oyster disease (3). These are just a few of the 33 non-native species that have been documented in marine waters and shorelines along the Maine coast in a preliminary count. While many non-native species are unable to survive, reproduce, and overtake native plants and animals in Maine's coastal waters, those that are successful become known as "invasive species."
