What do lionfish do to be invasive?
As lionfish populations grow, they put additional stress on coral reefs. For example, lionfish eat herbivores, and herbivores eat algae from coral reefs. Without herbivores, algal growth goes unchecked, which can be detrimental to the health of coral reefs.
What are some interesting facts about the lionfish?

What lionfish species is invasive?
Pterois volitans
Lionfish (Pterois volitans, Pterois miles), venomous fishes native to the Indo-Pacific and Red Sea, are the first invasive species of fish to establish themselves in the Western Atlantic (Schofield 2009).
When did lionfish become invasive?
In the Atlantic, adult lionfish have no known predators. Lab studies have shown that many native fish would rather starve than attack a lionfish. Whitfield, the fisheries biologist at NOAA, began to study the troublesome new invader in 2004. She looked for lionfish in 22 survey sites from Florida to North Carolina.
What problems are lionfish causing?
Invasive lionfish threaten native fish and the environment in U.S. Atlantic coastal waters. Invasive species are capable of causing extinctions of native plants and animals, reducing biodiversity, competing with native organisms for limited resources, and altering habitats.
Why do lionfish destroy reefs?
They have no natural predators in these waters and are thusly becoming rapidly overpopulated and depleting resources, out-competing every other native fish in the Western Atlantic Ocean, Gulf of Mexico and the Caribbean Sea and wreaking havoc on the ecosystem ecologically, environmentally and economically.
How do lionfish impact the environment?
Impacts. Lionfish are a predatory reef fish. They eat native fish, which can reduce native populations and have negative effects on the overall reef habitat and health as they can eliminate species that serve important ecological roles such as fish that keep algae in check on the reefs.
How do lionfish destroy coral reefs?
Where are lionfish a problem?

- Smartphone App! Divers report sightings.
How are lionfish destroying coral reefs?
Invasive lionfish disrupt the natural cycle of coral reef systems by competing with native predators and consuming large amounts of prey, leading to reduced recruitment and possible extirpation of native fish species.
What damage does the lionfish do?
What problems do lionfish cause?
Why are lionfish invasive in Florida?
An Invasive Species Introduced The lionfish problem started more than 25 years ago, when the first fish were released into the waters of South Florida, most likely by the aquarium trade.
