Pterois in frolida
Pterois are an invasive species that threaten Florida’s saltwater fish and wildlife.
Food habitsThey usually eat crustaceans (like crab) and small fishes

Lionfish were first reported off Florida's Atlantic Coast near Dania Beach in 1985; in the 1990s four reports were made near Miami, Boca Raton and Palm Beach and one report came from Bermuda. In 2000 the species began to be recorded off the Atlantic coasts of North Carolina, South Carolina and Georgia, while reports from Bermuda and Florida continued. By 2005 the first report was made from the Bahamas. The species has now been regularly recorded all along the east coast of Florida, with multiple observations throughout the Florida Keys, and they are widespread in the Caribbean. Individual lionfish have been collected or were observed in the northern Gulf of Mexico off Pensacola and Apalachicola in 2010.
INVATER OF FROLIDA
How did the INVASION start? The INVASION is most likely a result of escapes or releases from aquariums, either by accident or on purpose. There is one documented case of lionfish escaping from an aquarium located in a house damaged by Hurricane Andrew – the fish were seen swimming nearby after the storm. The “on purpose” introductions are assumed to occur from hobbyists who dumped them into canals (not knowing any better) when the fish either got too large for their aquariums or became unwanted. Genetic evidence from recent scientific results suggests multiple introductions.
