Imagine calmly walking barefoot in the shallow sea water and feeling the cool waves against your skin. You are enjoying a fun walk, and all of a sudden an intense pain hits your foot. You look down expecting to see a sharp rock or object, but there is nothing there. Nothing you can see. What you don’t realize is that you may have just stepped on one of the sea’s most dangerous creatures: rockfish. Today, let’s dig in and learn in depth about this captivating aquatic creature.
What is a rockfish?

Rockfish are big and tall poisonous fish which typically live in the warm waters of the Indo-Pacific, near places like Australia, Southeast Asia, and the Red Sea. They are extremely famous for their incredible camouflage abilities. They are known for having bumpy, rough skin and a unique body that blends perfectly with rocks and corals. Rockfish almost look like they are part of the ocean floor. They stand still and wait for unsuspecting prey to swim by, or worse, for a person to step on them.

Why is the rockfish dangerous?
The stonefish’s deadly secret lies in its sharp spines! These spines, found on the fish’s back, are not just for aesthetics – they are highly toxic. When a person steps on a stonefish, the pressure causes venom to be released from the spines to the person’s foot. And believe it! The pain is unimaginable. This venom is very powerful and can cause severe swelling, paralysis and even death if not treated quickly.
What happens after a sting?

A sting from a stonefish can cause serious problems. You will feel intense pain immediately, like being burned or shocked. The area around the sting will swell, become red and may bruise. The poison can also make you feel sick, causing nausea and dizziness. Breathing may become difficult, and in some cases you may even faint. In the worst situations, the poison can stop your heart, which can be fatal if not treated quickly.
If you are ever stung by a rockfish, the first thing you should do is get out of the water and immediately soak the sting thoroughly in warm water. It will help reduce the pain and break down the poison. After that, go to a doctor to get the right treatment.
Why do rockfish have poison?

The funny thing is that the venom of a stonefish is not only for self-defense and attacking predators! It also surprisingly helps them catch their food. The rockfish remains motionless and blends perfectly into its surroundings until a small fish swims close enough.
When that happens, the rockfish’s poisonous barbs release the venom and sting that instantly immobilizes the prey. While the poison keeps predators away, it also helps rockfish find their next meal.
