  • Pterois, commonly known as lionfish, is a genus of venomous marine fish found mostly in the Indo-Pacific. Lionfish are characterized by conspicuous warning coloration with red, white, creamy, or black bands, showy pectoral fins and venomous spiky fin rays.
    Hazard to humans
    Lionfish are known for their venomous fin rays, a feature that is uncommon among marine fish in the East Coast coral reefs. The potency of their venom makes them excellent predators and poisonous to fishermen and divers. Pterois venom produced negative inotropic and chronotropic effects when tested in both frog and clam hearts and has a depressing effect on rabbit blood pressure. These results are thought to be due to nitric oxide release. In humans, Pterois venom can cause systemic effects such as extreme pain, nausea, vomiting, fever, breathing difficulties, convulsions, dizziness, redness on the affected area, headache, numbness, paresthesia (pins and needles), heartburn, diarrhea, and sweating. Rarely, such stings can cause temporary paralysis of the limbs, heart failure and even death. Fatalities are common in very young children, the elderly, those with a weak immune system or those who are allergic to their venom. Their venom is rarely fatal to healthy humans, but some species have enough venom to produce extreme discomfort for over a period of several days.
    Lionfish are Invading the Atlantic and threatening reefs.
    Two of the nine species of Pterois, the red lionfish (P. volitans) and the common lionfish (P. miles), have established themselves as significant invasive species off the East Coast of the United States and in the Caribbean. About 93% of the invasive population in the Western Atlantic is P. volitans.[26]
    The red lionfish is found off the East Coast of the United States and the Caribbean Sea, and was likely first introduced off the Florida coast by the early to mid-1990s.[27] It has been speculated that this introduction may have occurred in 1992 when Hurricane Andrew destroyed an aquarium in southern Florida, releasing six lionfish into Biscayne Bay.[28] However, a lionfish was discovered off the coast of Dania Beach, south Florida as early as 1985, prior to Hurricane Andrew.[4][29][30] The lionfish resemble those of the Philippines, implicating the aquarium trade.[31] The lionfish may have been purposefully discarded by unsatisfied aquarium enthusiasts.[31] In 2001, NOAA documented multiple sightings of lionfish off the coast of Florida, Georgia, South Carolina, North Carolina, and Bermuda, and they were first detected in the Bahamas in 2004.[32] Recently (June 2013) they have been
