Royal cus Glesne ([ 1]), also known as Brunhiti, is commonly known as Dragon Palace Messenger, Bai Longwang, Dragon King Fish, Hairtail King, Paddle Fish, Fat Fish, Buy Cattle, Man, Pig Essence, Hundred Cattle, bn, and Earthquake Fish, and is one of the fishes of the order Actinidia. Widely distributed in tropical deep sea. It is the longest bony fish in the ocean with a bright silver body; The ventral fin is red and paddle-shaped, so it means "paddle fish" in English. The dorsal fin is also red, very long, as high as two stories, and looks like a mane crown from the top of the head. Rarely seen on the water. Some people occasionally see it and mistake it for a "sea snake". People usually think that they are monsters that sweep the bottom of the sea and destroy everything, and are mistaken for the legendary "dragons" in Southeast Asia. Chinese name Royal Cusglesne Latin scientific name Regalecus glesne alias oarfish (oarfish) or hairtail (hairtail) Chordata of animal kingdom, Actinidia, Cartilaginous Nuclesubclass, Eelliformes, families, genera and species of royal fish, which are distributed in the Pacific Ocean and Indian Ocean, the East Atlantic Ocean and the Mediterranean Sea and inhabit at 3000 feet (914.4m). The editing body of 1 has a flat side and a strip-shaped extension. Small head, like a horse's head. The body is bare and scaleless, with 5 ~ 6 rows of tumor-like protrusions on the side. Dorsal fin, red, without fins. The base of dorsal fin is long, and the first 1 to 5 dorsal fins are often filiform. The ventral fins become a pair of long filiform fins, and the ends expand into willow leaves. No anal fin. The caudal fin is not connected to the dorsal fin. The fish is silvery gray with blue-black stripes. The head is blue and the fins are red. Yellow croaker is the longest bony fish in the world. The maximum body length can reach 15 meters, but it is generally about 3 meters. Known to weigh 272 kilograms. [2] 2 Editing capture records There are few early capture records of this fish, so the research data about this fish is also relatively poor. Since ancient times, European fishermen have called it the "sea demon", while in Japanese legends, they call it the Dragon Palace Messenger. With the increase of modern capture records, various studies on yellow croaker are also known. Aristotle wrote in Animal History written in the 4th century BC: "In Libya, sea snakes are huge. Sailors sailing along the coast said that they had been attacked by sea snakes during their voyage. " In fact, this legendary monster is not a sea snake, but a deep-sea giant hairtail, which scientists call the longest bony fish in the ocean. Because this giant hairtail with a length of 18 meters has been living in deep-sea waters, it is difficult to capture and observe, and people know little about it. For thousands of years, it has been full of mystery. 1848 65438+1October1,the British warship "De Dallas" returned to Plymouth Port from east indies, and the report was submitted on board. According to the report, at 5 pm on August 6, when the ship was about 300 miles away from Africa in the South Atlantic, "Satorie, an alternate officer, saw a very strange object and swam quickly to the warship from the rear." Sartori immediately reported to the superior. When the captain, two officers and others heard the news, they saw a sea snake swimming in front of the ship. Witnesses estimate that the exposed part of the sea snake is 60 feet long, and the diameter of its head and neck is about 15 or 6 inches. It passed the "De Dallas" at a speed of more than ten miles per hour and swam southwest. Captain McQueen said that when it passed, it was "very close to the side below the stern." On September 28, 2000, an octopus with a body length of 5.7 meters and a weight of 35 kilograms was caught in the fixed net of Chongde in Hualien. 200 1 The octopus was caught by mistake near Hong Kong waters and east of Zhanjiang for the first time. In September 2006, a dying octopus appeared off the coast of Australia. This octopus is more than 8 meters long, with a flat side and a strip-shaped extension, and its head is similar to a horse's head. Fishermen nearby found it and dragged it to the shore with hooks. Soon the octopus died. 20 10 in may, another 3-meter-long body was found off the coast of Sweden. On May 3 1 2065438, an octopus appeared at the Taimali seaside in Taitung and was picked up by the public. Originally, people wanted to go fishing at the seaside, but they found an octopus 4. 1 meter long washed up on the coast. At first, they tried to push it back into the sea, but it was hit by the waves and finally they had to take it home. [4] 201310/3, Jasmine Santana, an instructor at the ocean centre in Catalina Island, Southern California, found a 18 feet (4.3 meters) long while diving in Toyong Bay off Santacatalina Island. The octopus died of natural causes, and fiber samples and videos have been sent to biologists in Santa Barbara for research. The body is now placed in ocean centre, Catalina Island, for students to visit. After that, the body will be buried in the sand. After the corpse decays, the bones will be exhibited for a long time. [5] On 201310/8, a 5.5-meter-long dead octopus was found again by the staff of the Catalina Oceanographic Research Institute on the beach of Toyong Bay in Catalina Island, California, USA. He suspected that these two amazing yellow croakers might have been washed to the beach by a powerful current and died because of constant flapping. [6]2065 438+03, 10/On October 28th, Guo Qiulin, a fisherman from Taitung, fished on the beach near the Jingyang security station of the 8 1 brigade, and even caught a fish with a tail length of 5 meters and a weight of several hundred kilograms (1 kg =0.6 kg). According to the fish database of Taiwan Province Province, the scientific name of earthquake fish is grouper, which lives 20 to 1000 meters below sea level. Because it often appears before and after earthquakes, it is also called earthquake fish. On March 7, 20 14, a 4.38-meter-long deep-sea "yellow croaker" was discovered by residents in Baimu Coast, Qi Xian, Yamaguchi Prefecture. This is the seventh discovery of Changmen store after 1999, and this one is large. [7] On April 8, 2004, 2065438, a rare living octopus was found in the shallow sea of Mexico, with a body length of 4.5 meters. The Shed Aquarium in Chicago organized a trip for experts. They found a live octopus in the clear water of Cortes, Mexico, with a body length of about 4.5 meters and a dorsal fin almost as long as the body. [3]3 Habitat and Reproduction Editor: The reproduction of yellow croaker is very slow, and the number has only doubled in about 14 years. In mid-June, 1 1 is the mating and breeding season for yellow croaker. At this time of year, countless octopuses gather from all directions near Savai Island in the South Pacific for collective mating. Scientists still haven't figured out how to locate the octopus so that it can come back here accurately every year. They form countless small groups, or dozens, or more than a hundred, and their flat slender bodies are twisted and twisted together, wriggling and rolling on the seabed covered with coral reefs. However, whether it is a larger group or a smaller group, there is only one female yellow croaker. And around it are its many pursuers. Through observation, scientists found that female octopus will lay eggs irregularly for about 654.38 million+pieces for two weeks in the breeding season. And every time it lays eggs, several male octopus around it will rush to excrete their sperm. I'm afraid no one can know which egg was fertilized by which male yellow croaker sperm. After mating, the males leave here quickly to avoid unnecessary killing each other. But in fact, scientists have not found cannibalism in the waters where yellow croaker breeds. After inference, scientists believe that a special enzyme may be secreted in the body during the breeding season to suppress this urge to kill each other. The mating males have left, but more males are coming. They will continue to pester the female octopus and wait for its next spawning. This process will last for about 2 weeks, and then they will disappear without a trace, leaving only a coral reef dyed white by fish eggs. [8-9] 4 Life Habits Editor Octopus is distributed in the deep sea, the Indian Ocean and the Pacific Ocean, and the subtropical deep sea from 72 degrees north latitude to 52 degrees south latitude. It is mainly active in the warm deep sea. [10] They live in the deep sea as deep as 800 meters, and it is known that the octopus that surfaced is sick or dying. However, some scientists believe that their vitality is very strong, even if only the first half of the body is left, they can still live. Many people think that the sea snake in the legend of ancient navigators comes from the image of yellow croaker! Their living habits are unknown. They only live in the warm waters of the Pacific Ocean and the Atlantic Ocean. They are the longest bony fish in the world. It is a carnivorous fish with fierce temperament. It preys on all marine animals that can be found and will kill each other. Its food includes all kinds of small and medium-sized fish, squid, krill and crabs. Although its huge body and ugly face are terrible, the octopus swims very slowly, and it doesn't have extremely lethal teeth like other octopus. It just floats on the bottom of the sea, and when the prey swims through its mouth, it is inhaled in one breath, and its hard upper and lower jaws are enough to crush crustaceans. The mouth of an octopus is different from that of an octopus. It is small, but it has two big sharp teeth. When it sees the big fish within its attack range, it contracts its body, and the fish swims on it, and it pops out like a spring to bite the fish. [1 1] Through research, scientists believe that all this vicious behavior of octopus stems from the lack of other fish and food in the deep sea where they live, and they have evolved for a long time to survive. This discovery once again confirms the eternal natural law of "the law of the jungle, the survival of the fittest". [12] 5 Discovery Case Editor 2014 On April 8, 2004, two octopuses with a length of 15.2 meters were found in the shallow waters of Cortes Beach, Mexico, which frightened the tourists nearby. [12] A group of octopuses swam to the shallow waters of the Sea of Cortes, most of which were 4.5 meters long, and the other two reached 15.2 meters long. The tourists were frightened by the arrival of these two behemoths. It is reported that these two octopuses are by far the longest bony fish in the world. 【 12】Zoroach is a kind of deep-sea fish, which usually lives below 900 meters, with a body length of 15 meters, and its living habits and life span are little known. Because of its mystery, it was mistaken for the legendary "sea dragon" or sea snake in ancient times. According to Japanese folklore, because they live in the deep sea, octopus can predict the arrival of earthquakes. [ 12]
