Lionfish

Lionfish

A Lionfish is any of several species of venomous marine fish in the genera "Pterois", "Parapterois", "Brachypterois", "Ebosia" or "Dendrochirus", of the family Scorpaenidae. The lionfish is also known as the Turkey Fish, Dragon Fish or Scorpion Fish. [ [http://www.aquariacentral.com/fishinfo/marine/lionfish.htm Mike McEwan, "A Fierce Predator: When the Lionfish shows its aggressive looks, its no bluff", "Aquaria Central"] ] They are notable for their extremely long and separated spines, and have a generally striped appearance, red, brown, orange, yellow, black, maroon, or white.

Native environment

The lionfish is native to the tropical Indo-Pacific region of the world, but various species can be found worldwide. Due to a recent introduction, the lionfish has recently been spotted in the warmer coral regions of the Eastern Atlantic Ocean and Caribbean Sea.

[ [http://www.nytimes.com/2006/09/08/nyregion/08fish.html Bruce Lambert, "A Spiny Invader Proliferates in L.I. Waters, and Scientists Wonder About Its Impact", - New York Times (September 8, 2006)] ] Successful breeding of the lionfish in captivity has not been looked upon.

Size

The common lionfish generally reaches a size of 30-35cm. Smaller lionfish (e.g., the Fuzzy Dwarf) are typically the size of a tennis ball (not including fins). There are many types of lionfish that vary in size. The lionfish has been one of the most venomous fish in the ocean bottom floor.

Venom

Lionfish have venomous spines that are deadly to their prey, but usually not to humans (though the venom is used purely for defense, not attack). If a human is envenomed, that person will experience severe pain and possible headaches and vomiting. A common treatment is soaking the afflicted area in hot water, as very few hospitals carry specific treatments. [cite journal |author=Aldred B, Erickson T, Lipscomb J |title=Lionfish envenomations in an urban wilderness |journal=Wilderness Environ Med |volume=7 |issue=4 |pages=291–6 |year=1996 |month=November |pmid=11990126 |doi= |url= |accessdate= ] [cite journal |last=Taylor |first=G. |title=Toxic fish spine injury: Lessons from 11 years experience |journal=South Pacific Underwater Medicine Society journal |volume=30 |issue=1 |date=2000 |issn=0813-1988 |oclc=16986801 |url=http://archive.rubicon-foundation.org/5828 |accessdate=2008-08-13 ] [cite journal |author=Vetrano SJ, Lebowitz JB, Marcus S |title=Lionfish envenomation |journal=J Emerg Med |volume=23 |issue=4 |pages=379–82 |year=2002 |month=November |pmid=12480019 |doi= |url=http://linkinghub.elsevier.com/retrieve/pii/S0736467902005723 |accessdate=2008-08-13] However, immediate emergency medical treatment is still advised, as some people may be more susceptible to the venom than others.

Feeding

Lionfish are voracious predators. When hunting, they corner prey using their large fins and then use their quick reflexes to swallow the prey whole. In captivity, lionfish can be trained to eat frozen brine shrimp, mysis, and krill.
