About the Lionfish
The common lionfish (Pterois miles) is frequently confused with its close relative, the red lionfish (Pterois volitans).
Lionfish venomous dorsal spines are used purely for defense. When threatened, the fish often faces its attacker in an upside-down posture which brings its spines to bear. However, its sting is usually not fatal to humans, though it can be. Envenomed humans will experience extreme pain, and possibly headaches, vomiting, and breathing difficulties. A common treatment is soaking the afflicted area in hot water, as very few hospitals carry specific treatments.
