To prepare it, it is necessary to milk the fish by collecting some venom from the spines. Only one is commercially available that neutralizes stonefish venom. If a stonefish stings you, you should go to the hospital because you might need the antivenom. It is suggested that hot water at 45✬ helps relief the pain. In order to treat a sting from stonefish, the spines and membranes must be carefully removed from the skin. #Stone fish how toHow to treat a sting from stonefish? And how to avoid it? In more extreme cases, the damages are so severe that people die.Īt a hospital in Pulau Bukom, an island near Singapore, 81 cases of stonefish stings were documented over a period of 4 years. The main symptoms caused by the neurotoxins of the venom are nausea, vomiting, local swelling, discoloration, sweating, cardiac arrythmias, respiratory distress, convulsions and necrosis. Yes! In fact, a sting from stonefish is incredibly painful and symptoms may persist for days. They remain motionless till a prey approaches. Red Stonefish sit still waiting for a prey. On the other hand, the main predators of stonefish are sea snakes, moray eels, sharks and rays. Then, vacuum is created by expanding the oral cavity, and they suck in their prey in less than 0.01 seconds. Instead, they remain motionless till a prey approaches. They don’t hunt or use their venomous spines to catch their prey. Stonefish usually feed on other fish and invertebrates, that are frequently swallowed whole. Because of this, people should have extra precaution when walking on beaches of coastal regions where they are present. Stonefish can be found in coastal waters and even lying on beaches. They are abundant around the tropical waters of Indian and Pacific Oceans as well as in the Red Sea. “Stonefish are abundant around the tropical waters of Indian and Pacific Oceans as well as in the Red Sea. In the wild, a stonefish can live up to 10 years. Only a small number survives and reaches maturity. When they hatch, newborn stonefish are already well developed.Įven though the females lay a huge amount of eggs, a great percentage of them is eaten by other aquatic organisms. Female stonefish release around a million eggs on the bottom of the sea floor, whereas the males release the sperm that will further fertilize them. Interestingly, stonefish can as well live out of the water for up to 24 hours. Sometimes it is possible to see organisms growing at their surface. They typically sit still near rocks and corals, or bury themselves in the sand, which allows them to take their camouflage to the next level. They usually live alone, and are sedentary animals that can be found at depths of 40 meters. There are five species of stonefish: some of them are marine, others are estuarine. Furthermore, the sabre glows which means it can be used for mating or territory defense. To deploy it, the stonefish only have to squeeze the cheeks muscles. Even though it isn’t connected to venom, this sabre is considered an additional defensive mechanism. Recently, researchers discovered that stonefish have a “lachrymal sabre” or, in other words, a switchblade beneath each eye. Moreover, they have two pelvic and three anal spines. It is used as a defense mechanism against predators. The amount of venom released is equivalent to the pressure applied in the spines. The venom is composed of neurotoxins and is released when pressure is put on the spine. They have the most advanced venom apparatus, composed of two bulky glands on the sides of each dorsal spine. Their dorsal fin has 13 short, thick spines that are raised when these fish feel threatened. In addition, stonefish have a raised bony structure on their head, with two small eyes.Īpproximately 1200 species of fish are thought to be venomous, but stonefish are among the most lethal. They have a large mouth and powerful jaws. #Stone fish skinTheir warty, scaleless skin along with their colors enable them to perfectly blend in with the surroundings. In average, they have a length of 30 to 40 centimeters, and they can weight up to 2kg. Stonefish size varies according the species. Stonefish sit still near rocks and corals, or bury themselves in the sand, which allows them to take their camouflage to the next level. In some cases, it is potentially fatal.ĭespite their potent venom, they are considered a delicacy in some Asian regions, if well prepared. Stonefish are the masters of disguise and a sting caused by these fish is able to produce extreme pain to humans. Meet One of the Most Venomous Fish on Earth:
