The document discusses the invasive lionfish species in Florida. It provides background that lionfish are native to the Indo-Pacific region but have become an invasive threat to Florida's marine life. Lionfish were first reported off Florida's coast in 1985 and have since spread throughout the Caribbean and Gulf of Mexico, reaching the northern Gulf by 2010. The invasion is thought to have started from aquarium releases, either accidental after storms or intentional from hobbyists dumping unwanted lionfish.

2. Introduce about Pterois
This fish is commonly
known as “LIONFISH”
Mostly live in
Indo-pacific
And act after sunset

3. Pterois in frolida
Pterois are an invasive species that threaten
Florida’s saltwater fish and wildlife.

4. Food habits
They usually eat crustaceans (like crab) and small fishes
WHY?
Crustaceans and fishes go to their nest to rest
Pterois need not invest their energy to find the prey

5. Pterois venom

6. Pterois venom
Their venom is a combination of:
protein, neuromuscular toxin
neurotransmitter called acetylcholine

7. Pterois
Ichthyotoxin = Ostracitoxin
Fugu
Eel

10. 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

11. 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.
