A man from Hebei catches a magical creature in the sea, and it glows when touched. What is this?
A few days ago, a netizen from Qinhuangdao, Hebei, went to the beach with friends to catch the sea, but unexpectedly found a very magical creature on the beach. Judging from the video taken by the netizen, the unknown creature can emit light by touching it gently with his hand, and it looks like a "night light". In this regard, many netizens have left messages below, jokingly claiming that this is a small night light from the underwater dragon palace. So, what is this? A man rushing to the sea meets a "night light", what will it be?
Although it looks incredible, the network is powerful, and some netizens soon recognized the true identity of this "night light". It turns out that it is a kind of marine creature. It is called "sea corn" by people on the coast. It is a "sea cactus", and it is one of its characteristics that it emits light. It is a mallet-shaped coelenterate with a long handle on the lower part. It mainly inhabits the sand and sand on the bottom of the sea. When night falls, it will stretch out collectively and emit a faint light. From a scientific point of view, "sea corn" emits light, which is actually related to the fact that it has luciferase and luciferin in its body. When they are stimulated by the outside world, they will show strong phosphorescence. The research believes that this may also be their self-protection method. a kind of. Because for animals unfamiliar with them, the sudden light will also make them afraid to act rashly. In the Yellow Sea and East my country Sea areas of our country, "sea corn" is actually not uncommon. Many people rushing to the sea have found them. For example, there was a guy in Liaoning, my country, who went to the beach after the low tide at night, and found a super large The "sea corn", which glowed when touched by hand, turned out to be like a big light stick, very beautiful. Speaking of which, there are not a few creatures that emit light on the earth. There are many kinds of marine creatures like "sea corn", and many of them are familiar marine creatures. So, other than "sea corn," what other sea creatures glow?
The first type is "Luminous Insects". In recent years, many friends have heard of "Blue Tears by the Sea". Simply put, the sea water glows with blue light at night, making it look like a dream. However, what many people don't know is that such a scene is caused by "noctilucent insects". As a protozoa living in the ocean, if they are numerous, they will gather together at night, accompanied by the sea water. It fluctuates and emits blue light under external stimulation, which is actually quite similar to "sea corn". The second is "jellyfish", which also look like "night lights" at night, because the protein composition of jellyfish is very special, which contains a magical substance called "Equilin" , it is also the key to the jellyfish glow. The third type is "firefly squid". They are a kind of squid, but they are different from the squid we are familiar with. Although they are not big, they can shine in the deep sea, but they cannot be seen on the coast of our country. So you may not be very familiar with them. From the distribution point of view, they are mainly in the Western Pacific. There are also "light-eyed fish", which are different from other light-emitting creatures in the ocean that emit light all over the body. "Light-eye fish" only have luminous eyes, which also makes them look very weird, even in the dark seabed, many times I can't see its body clearly, and I can only see two small bright spots swimming around in front of it. There are many similar luminous marine creatures, and studies have also found that many luminous marine creatures mainly inhabit the deep sea. A lifeline can not only "scare" natural enemies, but also attract prey to approach, and at the same time, it can also help them identify the same kind, etc. It can be said that this is also the magic of the evolution of the earth's organisms. Just like "sea corn", it is a very soft marine creature in itself, and it belongs to the lower end of the marine food chain. If it does not emit light, perhaps "sea corn" has already become extinct, and it is impossible to live in the ocean at all. have existed for so long and have never been at risk of extinction. Just like flying "fireflies", they are also very low-end insects, but they make themselves very special by emitting light. For many years, scientists have studied the purpose of fireflies. Courtship, warning, population regulation and many other purposes. The researchers said that the fact that living things emit light is a very common phenomenon in nature, including that people themselves also have "biological light", but not all living things can observe their "biological light". Only a small number of creatures will emit a dazzling light, so it will give people a very strange feeling. So, what creatures have you seen that glow? Welcome to leave a message and share with us!
