RESEARCHERS DISSECT lionfish to see what they are eating, if they are reproducing, and how quickly they are growing. This information can help to understand the impacts of the invasion and how best to respond.
"The invasion of lionfish (Pterois miles and Pterois volitans) may prove to be one of the greatest threats of this century to warm temperate and tropical Atlantic reefs and associated habitats. As the first marine reef fish invasive species to this region, lionfish are changing the culture of how reef managers view invasive species, the regional connectivity of marine reefs, and their vulnerability to marine invasions" - Dr. James A. Morris, Jr. NOAA
