That's the king squid, the biggest squid in the world! The king squid lives in the deep sea. There are legends of sirens in the seafaring civilizations of many countries. They all look very similar to squid. Modern people also have some fragmented knowledge of the giant king squid. Some seafarers in the sea night watch, once saw the squid up to 20 meters long tentacles in the deck sweeping, those who can be caught objects are rolled into the sea, the next day, people found by several rows of teeth bite through the barrels hanging on the side of the ship. During World War II, the U.S. Navy, a thousands of tons of destroyer in the night voyage suddenly found that the speed slowed down, but could not find any fault, when people sent it into the dockyard for repairs, only to find that its propellers have been sharp teeth bite through dozens of holes. Until today, when deep-sea diving is developed, people have not really taken a real picture of the king squid. Since ancient times, stories of terrifying sea monsters have circulated among fishermen and sailors around the world. In the legends, these sea monsters are often huge and weirdly shaped, and even have seven or nine heads. One of the most famous is the "Norwegian Sea Monster" described by Bishop Pang Bidan of Bergen in the year 752 in the Norwegian Museum, which is said to be "about a mile and a half around the back of its body, or should I say the upper part of its body, as if it were an island. ...... Later on, several shiny tips or horns appeared, sticking out of the water and rising higher and higher, some as tall as the masts of medium-sized ships, which were presumably the monster's arms, and were said to be able to pull the largest warships down to the bottom of the sea. Since the nineteenth century, with the development of modern zoology, the overly outlandish legends of sea monsters have gradually disappeared. But there are still some reports that deserve our attention: November 1861 and 0, the French warship "Alerton" from Spain's Cadiz on the way to Tenerife, encountered a 5-6 meters long, with two-meter-long tentacles of the sea monster. Captain Siegel later wrote: I think it was the great octopus which has caused so much controversy and which many people believe to be fictitious." Hierl and the crew harpooned it and put a rope around its tail. But the monster frantically flailed its horns and broke the harpoon and fled. Only a piece of flesh weighing about 40 pounds was left on the rope. On November 2, 1978, three fishermen in Newfoundland, Canada, found a huge marine animal stranded on the beach due to low tide, the fishermen said it was 7 meters long, some of the horned hand up to 11 meters long or more, the sucker on the horned hand was 10 centimeters in diameter, and the eyes were as big as a face plate. The fishermen hooked it with a hook and the monster struggled for a while and died soon after. The Belgian zoologist Heifelmans collected and analyzed five hundred and eighty-seven reports of sea monster sightings over a period of more than three hundred years*** from 1639 to 1966, and, excluding possible misreadings, deliberate deceptions, and unclear writing, found three hundred and fifty-eight credible. He entered all the details of these reports into a computer to analyze them and came up with nine different kinds of sea. Although these reports were not free from exaggeration, at least one of them was confirmed to be a sea monster that was previously thought to be "impossible": the giant king squid. In the 1870s, the remains of the giant king squid washed ashore on the Canadian coast on several occasions, at least once alive, and with the help of these entities, people finally learned something about the giant king squid. The king squid lives in the deep waters of the Pacific and Atlantic Oceans, with a body length of about 20 meters and a weight of about 2-3 tons, making it the largest invertebrate in the world. It is extremely ferocious, feeding on fish and invertebrates, and can fight with giant whales. There are often reports of king squid fighting with sperm whales abroad. According to records, once people witnessed a king squid with its thick horns and suckers dead entangled in the sperm whale, the sperm whale put all its strength to bite the king squid's tail. The two giants of the sea rolled violently, stirring up the turbulent waves, and then both sank to the bottom of the water without knowing what happened. Most of these fights are won by the sperm whale, but there have been cases where the king squid has suffocated the whale by clamping its nostrils with its tentacles. In this case, the sea monsters that people encountered in 1861 and 1878, as quoted earlier, were definitely king squid. How big is the largest king squid? This is a difficult question to answer. A king squid of 17.07 meters in length was measured to have a sucker on its horns with a diameter of 9.5 centimeters. However, there have been sucker scars of more than 40 centimeters in diameter found on captured sperm whales. From this, it is assumed that the king squid that fought with this whale could have been 60 meters or more in length. If there really is such a big king squid, it is not far from the legendary Norwegian sea monster.
