Yon ran de espès anvayisan yo konnen ki poze risk nan resif koray, ki gen ladan kèk alg, pwason, ak envètebre. Espès anvayisan yo se òganis ki gaye rapidman pou domine ekosistèm epi yo ka lakòz domaj ekonomik ak / oswa anviwònman. Anpil espès anvayisan yo entwodwi espès ki ka ogmante chans pou nouvo maladi ak diminye manje a ak espas pou espès natif natal. Sepandan, envaziv yo pa gen pou vini soti nan yon lòt kote; yon espès natif natal ka vin pwogrese si kontwòl natirèl li yo retire.

A range of invasive species are known to pose risks to coral reefs, including some algae, fish, and invertebrates. Invasive species are organisms that spread rapidly to dominate ecosystems and are likely to cause economic and/or environmental harm. Many invasive species are introduced species that may increase the likelihood of new diseases and decrease the food and space for native species. However, invasives don’t have to come from elsewhere; a native species can become invasive if its natural controls are removed.
