Venomous Fish and Their Defenses

Fish−all those fast little finned animals that have scales and swim in water.  Some of them take your breath away with their coloration.  Others, you may wonder what the fish did to be born with a mug like that.  All in all though, just harmless creatures of the sea that you might be lucky to see up close if you go snorkeling.

Whoa, back up a minute.  Harmless?  It might come as a surprise that there are actually more venomous fish than there are venomous snakes!1 You’ve probably even run into some in your day to day experiences.  The fins of catfish have a mild venom, for instance.  Granted, some of these fish don’t have quite the same wallop in their venom as others, but that doesn’t mean their defense isn’t painful for humans!  Here are some of the more venomous fish on the list, the ones you literally wouldn’t want to run into while enjoying the ocean.

Rabbitfish

Also known as Spinefoots, these fish come in a variety of species and colors.  They get their name from their tiny mouths which supposedly resemble a rabbits.  All of their fins have spines on them, and the rabbitfish sports 22 spines in all, each of which produces venom.   Luckily, the venom from these little guys is not deadly to humans, although the sting is painful, and rabbitfish are kept as pets by salt-water fish-lovers.  Their native habitat is the waters of the Indo-Pacific and the Mediterranean. 

Stonefish

A bottom-dweller, the stonefish’s coloration is how it gets its name.  The stonefish isn’t always very pretty because its goal is to blend in with its surroundings.  Although Reef Stonefish are brightly colored to blend in with the coral, other stonefish sport dull, rock-colored coat.  This is one fish that you wouldn’t want to met−or rather, step on−in a coral reef.  The Reef Stonefish is one of the most deadly fish in the world, and the venom of any stonefish, stored in spines along its dorsal fin, is fatal to humans if not treated immediately.  Stonefish live in the waters of the Indo-Pacific.
