Invasive species are species that have been introduced to an area that are not native to their own, and to some degree, cause damage to the ecosystem they have been brought to (Carlton, 1996). Species can be introduced both on land and in water. It is generally due to human activities that new species are brought in to different ecosystems. The two primary methods by which marine species are introduced globally are via ballast water transfer and hull fouling; however, there are other ways marine species can be introduced as well (Baz, 2003). Marine species can dramatically impact the environment that they invade as they compete with the native species, thus threatening the diversity and abundance in that ecosystem (Carlton 1996). However,
