Squid belongs to invertebrate mollusk. Among marine creatures, the squid swims fastest, and its swimming speed is very fast. Unlike ordinary fish swimming by fins, it moves rapidly by the reaction of water spraying from the funnel pipe on its belly, and its spraying ability is like rocket launching. It can make the squid jump from the deep sea and jump out of the water as high as 7 meters to 10 meters. Squid's body is like a cannonball, and it can fly about 50 meters in the air. The speed of squid swimming in seawater can usually reach more than 15 meters per second, and the maximum speed can reach 150 kilometers per hour. Sailfish, which is known as the champion of swimming speed among fish, has a speed of only 1 10 km per hour, so it has to admit defeat. Of all the squid in the world, the youngest is the baby squid. Its length is no more than 1.5 cm, which is about the size of a peanut and weighs only 0. 1 g. This subminiature squid lives in the aquatic plants in the shallow sea of Japan, and its appearance is very similar to that of ordinary squid, except that there is a sucker on its back, which can be adsorbed on the aquatic plants and will not be washed away by the sea. Usually, it rests on the aquatic plants. Once it finds its prey, it suddenly attacks. After eating, it returns to the aquatic plants to rest quietly, waiting for the next prey. The biggest squid in the world is the king squid. They generally live in the depths of the ocean, rest in the deep sea during the day and swim to the shallow sea for food at night. In the kingdom of squid, there is also a small firefly squid. It is a luminous creature, with three light-emitting devices on its belly and one around some eyes. The light it emits can illuminate 30 cm away. When it meets a natural enemy, it emits strong light, scaring the natural enemy into running away.

King squid lives in the deep sea. There are legends of siren in the maritime civilization of many countries. They all look very similar to squid. Modern people also have some fragmented understanding of the king squid. When some seamen were on the night shift at sea, they once saw squid tentacles as long as more than 20 meters sweeping across the deck, and all the objects that could be caught were swept into the sea. The next day, people found iron drums bitten by rows of teeth hanging on the ship's side. During World War II, a destroyer weighing thousands of tons in the United States Navy suddenly found its speed slowed down during the night flight, but no fault was found. When people sent it to the dock for repair, they found that its propeller had been bitten through dozens of holes by sharp teeth. Until today, when deep-sea diving is developed, people really took a real photo of the king squid.

Since ancient times, there have been terrible stories about trolls in the sea among fishermen and sailors all over the world. According to legend, these sea monsters are often huge and grotesque, even with seven or nine heads. One of the most famous is the "Norwegian Sea Monster" described by the Bishop of Bergen Pompidan in Norwegian Natural History in 752. It is said that "its back, or the upper part of its body, looks like an island for about a mile and a half. ..... Later, a few shiny tips or horns appeared, sticking out of the water and reaching higher and higher. Some of them were as tall as the masts of medium-sized ships. These things were probably the arms of monsters, and it was said that the largest warships could be pulled down to the bottom of the sea.

Since the 19th century, with the development of modern zoology, the absurd legend of sea monsters has gradually disappeared. But there are still some reports that deserve our attention:

186 1 year 1 1 month and 0, the French warship "Arden" was on its way from Gaddis, Spain, to Tenerife Island, when it met a sea monster that was only 5-6 meters long and had two meters long tentacles. Ciel, the captain, later wrote: I think that is the big octopus that has caused a lot of controversy and many people think it is fictional. "Ciel and the crew put it in the harpoon, and put a rope around its tail. But the monster waved wildly and broke the harpoon and fled. Only a piece of meat weighing about 40 pounds was left on the rope.

1978 1 1 On February 2, three fishermen in Newfoundland, Canada, found a huge marine animal stranded on the beach because of low tide. The fishermen said that it was 7 meters long, and some horned hands were more than 1 1 meter long, and the diameter of the sucker on the horn hand was/kloc. Fishermen hooked it with hooks, and the monster struggled for a while and soon died.

Belgian zoologist Heifmans collected and analyzed 587 reports of finding sea monsters from 1639 to 1966 for more than 300 years, and excluded 358 cases that might be wrong, deliberately deceptive and unclear, and considered them credible.

He entered all the details in these reports into the computer for analysis and got nine different kinds of seas. Although there are still exaggerated elements in these reports, at least one of them has been confirmed by the sea troll that people thought was "impossible": the king squid.

In the 1870s, there were several cases in which the remains of the giant squid were washed ashore on the coast of Canada, and at least one of them was still alive. With the help of these entities, people finally learned something about the giant squid.

The king squid lives in the deep waters of the Pacific Ocean and the Atlantic Ocean. It is about 20 meters long and weighs about 2-3 tons. It is the largest invertebrate in the world. Its temperament is extremely fierce, it feeds on fish and invertebrates, and it can fight giant whales. There are often reports abroad that the king squid fights with the sperm whale. According to records, once people witnessed a king squid clinging to a sperm whale with its thick horn hand and sucker, and the sperm whale tried its best to bite the tail of the king squid. Two behemoths in the sea rolled violently, stirring up the turbid waves, and then both sank to the bottom of the water, and they did not know where to go. Most of this kind of struggle is that the sperm whale wins, but there have also been cases where the king squid pinches the whale's nostrils with tentacles and suffocates the whale.

From this point of view, the sea monsters that people encountered in 186 1 year and 1878 mentioned above are definitely the king squid. How big is the biggest king squid? This question is difficult to answer. People once measured a squid with a length of 17.07 meters, and the diameter of the sucker on its horn hand was 9.5 cm. However, from the captured sperm whale, sucker scars with a diameter of more than 40 cm have been found.

It is speculated that the king squid who fought with this whale may be more than 60 meters long. If there is such a big king squid, it is not far from the legendary Norwegian sea monster.
