In the past, many people always believed that fish were silent animals. In fact, this is not the case. Many fish can make different sounds. Some fish make sounds by flapping their gills, rubbing their dorsal fins or bones, or biting and filing their teeth. Others release gases from their swim bladders and use the vibration of their swim bladders to make sounds. The sounds made by different fish are different:
Pufferfish
The sound made by the small yellow croaker is like a frog, and the sound made by the anchovy is like the harsh sound played by a beginner. Sounds, the cry of the snapper is like the grinding of the teeth of a sleeping person, the cry of the yellow crucian carp is like the sound of the wind blowing on the leaves, the cry of the puffer fish is like the barking of the dog, the The cry of a large yellow croaker is like the sound of an engine coming from afar,the cry of the bream is like the sound of a distant engine, and the cry of the bream is like the sound of the wind blowing on the leaves. It sounds like moaning or deep sleep. There are also sounds that some fish make sound like bells, others like rolling thunder, others like an accordion bass ensemble, and still others like heartfelt singing. Some of these sounds sounded like the sound of a ship's propeller, and others like the sound of a submarine sailing. As a result, inexperienced sonar soldiers often became nervous and mistakenly thought the enemy was attacking. Fishermen can tell where the fish is just by listening to the sound. Li Shizhen in the Ming Dynasty recorded that the yellow croaker “can sing when it comes out of the water, and its sound is like thunder. Fishermen use bamboo to explore the water bottom. When they hear the sound, they lower the net. to intercept it."
Fish is an important part of human life. It is a very important non-staple food and an important source of protein for people. Fish meat contains 10-30% protein, including 8 types of amino acids such as lysine, tryptophan and leucine, which are necessary for the human body. It also contains plenty of easily absorbed fats, sugars and B vitamins. Fish skin can be made into fish skin powder and beautiful fish skin clothing. Fish scales can be used as fish scale glue, soy sauce, phosphorescent powder, calcium phosphate, hydrochloric acid, urea and other industrial raw materials and chemical reagents. Fish scale glue can be used as medical film and x-ray film. Fish bones can be used to make bone meal, fish offal can be used as pesticides,fish oil can be used to make soaps, paints, lubricants, etc. Fish gall is the raw material for making artificial bezoar, fish gills can be used to make ichthyocolla, and ichthyocolla can be made into industrial adhesives and used in surgical procedures. It can be said that the whole body of the fish is full of treasures. Fish are also a treasure trove of medicinal materials, and more than 90 types of medicinal marine fish have been identified. For example, "Conger eel is mainly used to treat hemorrhoids and fistulas and kill various insects." Cod liver oil is mainly used to treat vitamin A deficiency and seahorse has effects on fitness, pain relief, birth promotion and heart. reinforcement. Deoxyribonucleotides extracted from herring testicles are good forthe proliferation of the patient's leukocytes. Reducing pollution therefore constitutes an important step in the protection of marine biological resources.
In life, many people must have never been to the bottom of the sea, and they don't know what special sounds exist in the ocean. Many people think there is. there are no other sounds in the sea except the sound of the waves. , all think that the sea is very calm and in a very calm state, but the situation is not what we think, so there are still a lot of noises in the sea, such as the sounds of some sea animals, < /strong>Whales, dolphins,pufferfishand seahorses, etc., all make sounds to communicate. It's just that we can't hear these sounds on the shore. Of course, in addition to these sounds, there are also other more unique ones, such as the sound of waves and aurora sashimi, which are proevoked by the collision of auspicious objects. storms and ocean waves.
Actually, the ocean is not silent. It makes all kinds of strange sounds, but it's hard for us to hear them because there are all kinds of creatures in the ocean, especially whales. We all know that whales are very huge creatures in the ocean, and we can hear their cries whether in the sea or on the shore.And whales are very large individuals, so their screams are also very huge. . The cry of the whales in the sea is as beautiful as the song. Of course, in addition to the sounds of whales, there are also the sounds of many animals, such as pufferfish and seahorses. They all make certain sounds. . In addition to the sounds of animals in the ocean, the most important are the sounds of waves and sea spray. We all know that the sound we hear in the sea is the sound of waves, but waves also haveif a certain sound. the waves hit the bodies of fish or There are unique sounds coming out next to the rocks, especially near some caves or cliffs. The sounds are even more beautiful, as beautiful as the melody of the music. As long as we listen carefully, we will experience a very noisy state, and sometimes it is particularly beautiful, because many animals in the ocean will make unique sounds to communicate, or to serve as a warning to prevent natural enemies. the sounds made by these marine animals and sea water, the most important is the unique sound effect of aurora and waves, which is aurora sashimi. Because polar storms are very fast and some unique frequencies are also produced in the ocean. , both When these frequencies collide, a certain sound effect occurs.
The ocean is therefore not silent. It also has many sounds, but some are subtle and othersyou are stronger. As long as we listen carefully or discover, you will feel it in the ocean. , there is actually a different world.
