Introduction:
Lion fish always reminds me of those femmes fatales in Hollywood movies: beautiful and vicious.
But for lionfish, whether it is gorgeous appearance or poisonous thorns, these are just ways and means of survival obtained by natural selection, not weapons for attacking cities and plundering land.
If there is no threat or attack, lionfish will be happy to live a "lady" life leisurely in the sea. When we fully understand its lifestyle, we may think that the toxicity of lionfish is also excusable. After all, it's so beautiful. In front of such a gorgeous creature, there is only so much charm of a Christmas fireworks.
Swimming butterfly
Lion fish is a very popular marine ornamental fish in recent years. Its pectoral fins and dorsal fins have long fins and spines, which are similar to those worn by the ancients, so it is also called squid. These fins and thorns look like flags inserted behind Peking Opera actors. They are magnificent and look very bright and colorful in the sun. They often drag their broad pectoral fins and long dorsal fins to swim leisurely in the sea, swimming freely and not afraid of threats in the water at all. Like a flower flying freely among corals.
Lion fish is also called "turkey fish" because it looks like a turkey, so when someone mentions turkey fish, don't be confused. He is talking about lion fish. Generally speaking, the pectoral fins of lionfish are not separated, but some species of lionfish are separated one by one and bloom like fireworks. This lionfish is also called "flame fish". The lionfish has the same stinger as its similar stone dog male, but its lifestyle is completely different from that of the stone dog male who uses mimicry camouflage. Lionfish are brightly colored and beautifully dressed, and always show their gorgeous dance skirts in the sea without scruple.
It looks very beautiful.
Lionfish can be so carefree and arrogant in the sea, mainly because they have long fins on their dorsal fin, pectoral fin and anal fin. These fins have poisonous glands at the base and poisonous needles at the tip. Under normal circumstances, these fins are completely unfolded, just like hedgehogs, which makes predators who want to attack lionfish at a loss.
Of course, such a well-defended lionfish is not completely without weaknesses. Its abdomen is not protected by thorns, and lionfish knows this. Therefore, when in danger or at rest, lionfish will stick themselves to the rock wall with a sucker in their abdomen to seek self-protection.
All cetaceans have stingers on the dorsal fin and pectoral fin, which are mainly used to resist the threat of the same species or predators. Don't underestimate these thorns. As a lionfish, this is the most proud deadly weapon. Because lionfish is a kind of shallow water fish, most of them live in shallow water, so they are often seen when snorkeling. Its gorgeous appearance will soon attract your attention, but don't be confused by this color, let alone touch it easily. Lion fish is a famous "poison king" in the ocean. Their toxins can cause severe pain, swelling, and sometimes convulsions, and in the worst case, they may lead to death (this situation is extremely rare and usually only happens to people who are allergic to toxins).
The stinging process of lionfish is simple and effective. When you try to get close to it, it will shrink back. This is not a sign of fear, but a preparation for attack. Its attack usually occurs in the blink of an eye. When the stinger penetrates into human tissue, the poison sac at the root of the stinger is ready. Lionfish can release venom by squeezing it, and the venom is injected into human tissue through the wound caused by the stinger. This also tells us that if the sting is heavier and deeper, the harm caused by venom will be greater.
Come on, * * * Dance a song of death.
Lionfish are alert hunters and potential predators. They exert their physical strength to the extreme and are powerful in lethality. One of the most striking features is that they use pectoral fins.
The pectoral fins of lionfish have different shapes: some are like bird feathers, some are like spears, and some are like soft leaves. But no matter what it looks like, each one is extremely gorgeous and gorgeous. When they prey, they use pectoral fins to perform many actions. First, it gently shakes its pectoral fin back and forth, just like a Spanish girl's group dance, making the whole body move forward slowly. The whole action looks like a cheetah slowly approaching an antelope on the grassland. Not only that, their swinging pectoral fins also created a barrier, which restricted the activities of their prey and forced them to retreat slowly, and finally they were driven into a narrow corner.
When lionfish get closer and closer to their prey and are ready to swallow it in one gulp, their pectoral fins will stand up and then start to shake rapidly, which is similar to the shaking of rattlesnakes' tails. This move is to attract the attention of prey, but also to make lionfish pay more attention to prey. When the prey shrank in the corner and was confused by everything in front of him, the lionfish suddenly put away all its fins and swallowed it as quickly as possible in the blink of an eye.
Lionfish often swing its huge pectoral fin from the bottom of the water, looking for some small fish hidden under the sand or in cracks. This predation dance will show some differences among different kinds of lionfish. For example, the dorsal fin and pectoral fin of the dwarf lionfish vibrate when hunting. On the other hand, Fu Manchu lionfish vibrates its dorsal fin back and forth with a unique rhythm, and only shakes the tip of radial pectoral fin when hunting.
This vibration of backstab and pectoral fin is very common in the predation process of lionfish, which is their unique predation mode, and this action also enhances the predation ability of lionfish to some extent.
Crisis management after kissing
Fortunately or unfortunately, there is still the possibility of meeting a lionfish while snorkeling and being "kissed" by it.
No matter how beautiful the lionfish you meet underwater, you should be alert while feeling lucky. Maybe you didn't intentionally disturb its life, but if you strayed into their territory, they might attack you because you were "offended". Their stingers can easily penetrate thin gloves, so wearing ordinary gloves can't effectively prevent them from being stung. Therefore, when snorkeling, it is recommended to wear diving suits and thick gloves to minimize the possibility of injury if you are in those waters where you often encounter underwater toxic creatures.
If you can't stand the temptation to approach and exceed the "safety standard" of lionfish and get stabbed by it, it is very important to seek the help of professional medical personnel immediately. If the wound is not handled properly, the pain will be aggravated and may cause a series of long-term problems.
Of course, before seeking medical assistance, you can also do some preliminary treatment yourself. First, check the wound for broken stab residue. If so, take it out. Generally speaking, the broken thorn is easier to take out. But be careful, it may hurt when you take the broken thorn. It is very likely that my right hand will be injured and I am not used to doing such fine work with my left hand. At this time, you can ask others for help, and it will be more convenient to use tweezers. If the puncture is close to blood vessels or nerves, it is recommended not to do it yourself, but to find professional medical personnel.
After the broken thorn is treated, hot water treatment is needed. The venom of all cetaceans is made of protein, and protein is very sensitive to heat, so the toxin will decompose quickly when heated. You can soak the injured part in hot water. The temperature should not be too hot, about 43-46 degrees Celsius. Excessive temperature will make the problem worse.
Of course, the most important thing is to go to the hospital as soon as possible and explain what happened to the doctor. Don't expect every doctor to happen to be a lionfish expert, try to explain it clearly if possible. Doctors usually apply hot compress to the wound for 30-90 minutes first, just like the previous pretreatment, which can minimize the pain. After that, the doctor may give you some medicine for internal and external use.
Remember, after the doctor has treated the wound, you should always pay attention to the changes of the wound to prevent bacterial infection and the spread of toxins.
