Good to know about Lionfish
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. 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. However, immediate emergency, medical attention is strongly recommended, as some people are more sensitive to the venom than others.
