Dendrochirus biocellatus

Note

 * The Lionfish is one of the most venomous fish on the ocean bottom floor. Lionfish have venomous dorsal spines that are used purely for defence. When threatened, the fish often faces its attacker in a head-down posture which brings its spines to bear. However, a Lionfish's sting is usually not fatal to humans. If a human is envenomed, that person 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. (Erickson.)However, immediate emergency medical treatment is still advised, as some people are more susceptible to the venom than others.
