Invasive species become introduced to a non-native habitat through various ways such as accidental introduction, intentional introduction, and natural dispersal. Accidental introduction can happen when non-native species hitchhike on ships, airplanes, or cargo shipments, or by unintentionally releasing pets or aquarium species into the wild. Intentional introductions occur when a non-native species is intentionally brought into the new habitat for various reasons such as for agriculture, hunting, or ornamental purposes. Lastly, some species can naturally disperse to new habitats through wind, water, or animal transport.
