Invasive Species

An invasive species is a non-native species introduced to an area that has an adverse economic, ecologic, or environmental effect on the native ecosystem^[1]. Invasive species spread and excel in the ecosystems that they invade because of a lack of competition or a lack of predation from native organisms. In the context of coral reefs, invasive species frequently refers to the lionfish, which is native to the Pacific and is currently invading the Caribbean Sea and Atlantic due to its voracious appetite and lack of natural predators.
