Lionfish Facts

10 Facts on Lionfish

The Lionfish is not actually a specific fish but the name of a family of fish that share very similar characteristics. Most commonly Lionfish have a stripy coloration but all are noted for the long spines that seem to spray out from all over their bodies.

The lionfish is quite beautiful to observe as it often moves very slowly: they sometimes seem to just hover. However, encountering a group of lionfish on a night dive can often seem quite haunting for the same reason: at night their hovering manner can appear to be literally ghostly.

If you have never heard of lionfish (or even if you have) you may not be aware of much about them. This lionfish facts page is designed to provide you with some interesting details about this family of fish.




Facts About the Lionfish

  1. Lionfish are generally found in the Indo-Pacific region. Having said this, the lionfish is spreading its wings (so to speak) nowadays and so can also be found in the Caribbean Sea and the East Atlantic.
  2. Beautiful but deadly? Beautiful yes, but deadly no… unless you are very unlucky. Lionfish are classified within the family Scorpaenidae (sound like to scorpion to you?). Like scorpions, lionfish can sting. The flowing but sharp spines that cover a lionfish’s body deliver a potent toxin. The toxin is strong enough to kill a lionfish’s natural enemies but it is not likely to kill you. Having said this, being stung by a lionfish as a human can be very serious: a lionfish’s toxin can cause extreme pain, headaches, dizziness, vomiting and respiratory difficulty. Although the toxin is unlikely to cause fatality in humans, people more susceptible to it have died as the result an overly close lionfish encounter.
  3. As a result of the above fact, the lionfish is one of the most toxic fish on earth.
