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, and Scorpion Fish. The lionfish are voracious predators. When they are hunting, they corner prey using their large fins and then use their lightning quick reflexes to swallow the prey whole. They are notable for their extremely long and separated spines, and have a generally striped appearance, red, brown, orange, yellow, black, or white. 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. Successful breeding of the lionfish in captivity has not been reported. Lionfish have venomous spines that are deadly to their prey, but not to humans. If a spine punctures you, you will experience severe pain and possible headaches and vomiting.
