Lionfish are such posers! These elegant creatures sure bring a sense of peace to the dives. But those spines are chock-full of poisons! Really painful stings from these guys.
"
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. Lionfish are an invasive species in the Atlantic Ocean and the Caribbean Sea regions. Successful breeding of the lionfish in captivity has not been reported. In early 2009, the Lionfish was spotted in the Florida Keys, seemingly increasing its range. They have also spread throughout the Bahamas in the process decimating indigenous reef fish.
Size
There are many types of lionfish that vary in size. The common lionfish generally reaches a size of 30-35cm, while smaller lionfish, like the Fuzzy Dwarf, are typically the size of a tennis ball, not including fins.
Caution
NOAA encourages everyone (divers and fishers) to be extremely cautious and avoid contact with the venomous spines of the lionfish. Although they are not deadly, they are very painful.
Venom
The lionfish is one of the most venomous fish on the ocean bottom floor. Lionfish have venomous dorsal spines that are used purely for defense. 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. However, immediate emergency medical Feeding
Lionfish are voracious predators. When hunting, they corner prey using their large fins and then use their quick reflexes to swallow the prey whole. In captivity, lionfish can be trained to eat frozen brine shrimp, mysis, and krill.
Predators
The lionfish have very few natural predators, but the grouper and other lionfish have been found with lionfish remains in their stomachs."
