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.[1] 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.[2] Lionfish are an invasive species in the Atlantic Ocean and the Caribbean Sea regions. [3] 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.
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 envenomated, 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.[4][5][6] 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.
