Invasive species are non-native species that cause environmental or economic harm to a specific area. Invasive species are the second leading cause of species extinction and loss of biodiversity in aquatic environments worldwide. Invasive species are often introduced in ballast water (water held in the bottom of ships to increase stability) or through hull fouling (organisms attaching themselves to the hull of a ship). As these ships travel internationally, organisms are released in new environments. Invasive species can also be introduced intentionally or accidentally. Invasive species are often found in estuarine habitats since these areas are rich in nutrients and often the location of ship ports.

Almost half of the species on the Federal Threatened or Endangered species lists are at risk primarily because of invasive species." [The University of Georgia Marine Extension Service]
