How big is the world's largest squid? Here is the size of the world's largest squid I brought you.
How big is the world's largest squid?
The king squid, usually inhabiting deep-sea areas, is mainly produced in the North Atlantic Ocean and the North Pacific Ocean. It is estimated to be about 20 meters long and is one of the second largest mollusks and invertebrates known at present. At the beginning of 20 13 1 month, the Japanese NHK TV station and the American Discovery Channel filmed the squid swimming in the deep sea for the first time. The shooting team dived into the deep sea of 630 meters in the North Pacific Ocean by submersible, where the 3-meter-long king squid was photographed. This is the first time in the world that a dynamic image of the king squid has been photographed in the deep sea. In the middle of 20 14 1 month, through the efforts and cooperation of Japanese biologists, NHK and Discovery Channel, they experienced 1000 voyages and more than 400 hours of diving search, and finally photographed the giant squid in the sea at a depth of 630 meters. The biggest king squid is 80 meters long and weighs 50 tons. Is the invincible overlord in the deep sea.
Squid king is one of the largest invertebrates known in the world and the second largest squid in the world, with a body of18-20 meters. Generally, the juvenile king squid is 8-10 meter long, the adult king squid can be as long as 20 meters, and the largest king squid can grow to 80 meters or even longer, weighing 50 tons. Their eyes are surprisingly large, with a diameter of about 35 cm; The diameter of the sucker is also above 8 cm. The king squid lives in the deep sea, rests in the deep sea during the day, swims to the shallow sea for food at night, feeds on fish, and can catch prey in the dark sea. It often fights to the death with sperm whales that dive into the deep sea for food. Sperm whales are often scarred, but the remains of king squid have been found in their stomachs. People haven't seen the king squid staying in its habitat. People can only learn some information about these animals through those giant squid that float to the surface of the sea or are washed ashore by the sea after death or injury. The body is cone-shaped, the back is suddenly thin and narrow, the length of the trunk is about 4 times of the width of the trunk, and there are nearly round pigment bodies with the same size on the body surface. The fleshy fin is short, and the length of the fin is about 1/3 of the length of the trunk. The rear parts of the two fins are slightly peach-shaped, without prophase drooping, and the fins are connected with the jacket. The myofilament of the oral membrane is connected with the dorsal margin of the fourth pair of wrists. The 1 wrist is shorter, the other three pairs of wrists are longer and similar in length, and the wrist pose is generally 3? 2? 4? 1; The length of wrist 2-4 is about 4/5 of the length of the trunk, and there are two rows of wrist suction cups, and the horny ring in the suction cups has teeth; The fourth pair of male wrists is stylized, and the top sucker is specialized into two rows of fleshy processes. Touching the wrist is very prolonged, about 2.5-4 times the length of the wrist; Wrist-touching spikes are slender, with 4 rows of suckers, which can be divided into obvious carpal bones, palms and fingers; Two rows of suction cups in the middle of the palm are enlarged, and the suction cups have sharp teeth; There are dense clusters of suckers in the carpal bones, with 6-7 rows of suckers interspersed with hemispherical bulbous processes; The wrist-touching handle is provided with pairs of alternately arranged sucker and bulbous processes, which are arranged gradually from near to far. The inner shell is needle-shaped, the blade axis is thick, the ribs on the blade axis are thin, and the back end of the inner shell has a hollow narrow longitudinal rhomboid coccyx. No light emitter. The maximum trunk length is 6m, the total length is mostly 6- 12m, and the maximum length is 20m. Maximum weight 1000kg.
King squid lives in the deep sea. In the maritime civilization of many countries, there are legends of siren, such as Clegan. 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 rolled into a scrap iron by tentacles. Norwegian magazine Nature. For a long time, the legend of "giant squid" has been circulated among sailors, such as the legend of "Kraken Tentacles Of The Deep craken" in Norway. Alfred the Great, the medieval king of South England, once said, "On the bottomless sea, Kraken Tentacles Of The Deep is sleeping. It has been sleeping for centuries and will continue to sleep on the huge sea worms. Until one day, the flame of sea worms will warm the bottom of the sea, and people and angels will witness it. It will rise from the bottom of the sea with a roar, and everything on the sea will be destroyed. "
Appearance characteristics of giant squid
According to the Guinness Book of World Records, the giant squid that people saw in Newfoundland in 1888 was the largest squid ever recorded. It was 1 8.3m long and weighed1ton. Scientists have found that the size of the giant squid's beak has a certain relationship with its body size, so it is speculated that the average adult giant squid can grow to 6-12 meters and weigh 50-300 kilograms.
It is worth noting that the giant squid is not grown up by ordinary squid, but a unique species in the squid family. Generally speaking, their size is determined by the amount of food and the nutritional value of food. Therefore, they eat more, but their metabolism is much slower. Therefore, the joule energy required to support each kilogram of body weight is much less.
Giant squid, also known as King Squid, has smaller larvae than ordinary squid. It is reported that the largest giant squid in the deep-sea waters of the Pacific Ocean and Atlantic Ocean can reach 20 meters in length and weigh about 2-3 tons, making it the largest invertebrate in the world. Its temperament is extremely fierce, it feeds on fish and invertebrates, and it can fight giant whales. In fact, the "big squid" can generally grow up to 18 meters long and weigh 900 kilograms.
How big is the giant squid ever found in the world, and why are the animals in the deep sea so big?
There are two kinds of creatures on the earth, terrestrial creatures and marine creatures, and there is a big gap between them in terms of lifestyle and habitual body shape. However, large creatures can often be found in the ocean, because they have to ensure their organs can be safe in the high-pressure place like the ocean. It is recently discovered that the world's largest giant squid is 8 meters long and weighs 250 kilograms.
First of all, we all know mullet, which is not very delicious, and when caught, it will want to spray black liquid like ink on its face, which looks disgusting and only exists in the ocean. Generally, mullet is not big, because it lives near the ocean; But the giant squid is different. It lives in the deep ocean, where the pressure of water is terrible. In addition, tsunamis often happen. Their bodies must be very large to ensure that the memory organs are safe and they can walk happily under the sea. At the same time, they are also the largest invertebrate living in the world, and their living habits are no different from ordinary mullet.
However, because they live in the deep sea, scientists have always found few of them. After all, the scientific and technological requirements for deep sea exploration are too high, and the giant squid itself has little research value, which leads to the discovery of many samples and many of them are incomplete, and their fierce temperament is easy for everyone to know, and their combat effectiveness is not bad; The latest discovery of the largest giant squid was found on the beach in southern Australia around 2007. It was 8 meters long and weighed 500 Jin. What kind of concept is this? The height of 3.5 Yao Ming and the weight of two O 'Neill!
The reason why marine organisms are generally large in size is to protect their own survival. The ocean is not only under the strong pressure of seawater, but also has many unknown risk factors. Without a large size, it is death when encountering a tsunami.
The giant sea monster king squid, 20 meters long, why did it become a dish for sperm whales?
Although the giant squid sea monster has always been regarded as a legend and rumor, in the real world, large squid does exist, and there are many records at present. Among them, King Squid and King Sour Squid have been confirmed as existing species. They are the top predators in deep-sea waters, but they are also the Chinese food of sperm whales. Then why do they become the dish of sperm whales?
Two kinds of deep-sea "squid" sea monsters
We have to start with two kinds of "squid" sea monsters. The king squid is a species of Squid-King Squid-King Squid. It mainly lives in the deep sea of the Pacific Ocean and the Atlantic Ocean, and is mainly distributed in the waters with a depth of 300 meters to 3100 meters. .
Scientists estimate that the total length of adult male squid including tentacles can reach14m ~ 20m, and only tentacles can exceed10m. It is called one of the largest invertebrates known in the world together with the squid.
According to the current findings, there is still a gap between the weight of the squid and the king's sour pulp. King Physalis is a species of Cetaceae-Ophiopogonidae-Peacock Physalis-King Physalis-King Physalis.
The scientific name of King Sauerkraut is actually Giant Squid with Middle Claw. According to the current findings, King Sauerkraut mainly lives in the waters near the South Pole. They also like to haunt the deep sea, mainly living in the water with water depth1000 ~ 2000m.
Although its weight is heavier, the maximum weight can reach 750 kilograms, but in fact its length is not longer than that of the king squid, about 6- 18 meters. Compared with humans, king squid and king squid are much bigger.
Both king squid and king squid can be said to be the top predators in the deep sea, mainly relying on hunting large deep-sea fish and other cephalopods for a living. Through the discovery of fishermen's fishing at present, we know that the king squid is a very cruel predatory animal. They will catch the target prey with long tentacles, then use serrated suction cups to clamp the sides of the prey and send them to their mouths, and then their beaks will cut the prey into pieces.
As for the predation mode of the king squid, we still don't know. Scientists guess that their predation mode should be similar to that of the king squid, and their prey is similar, mainly deep-sea fish.
In principle, King Squid and King Soup Squid are big enough, and they are top predators in the deep sea. They should have no natural enemies, but in fact they have the same natural enemies, that is, sperm whales.
The natural enemy of the squid sea monster: sperm whale
Sperm whales are the largest toothed whales in the world, and they have obvious hermaphroditism, and the males are bigger. The average length of adult male sperm whales is 14~ 16 meters, and the weight is about 40~45 tons, while the average length of adult female sperm whales is10 ~/kloc.
Sperm whales are widely distributed, and they can be seen in the three oceans of the world. They are widely distributed in the ice-free waters of the world, and scientists have found them in the equator and the South Pole.
More crucially, sperm whales are often found in waters with a water depth of 1000 meters. That is to say, the deep sea frequented by sperm whales is also the waters frequented by King Squid and King Soup Squid. Sperm whales also like to feed in the deep sea area. They like to eat squid very much, mainly feeding on a variety of squid and deep-sea fish. Female sperm whales like to catch squid weighing between 0. 1~ 10 kg, and occasionally prey on large squid; Males also like to catch squid, but they prefer large squid. Therefore, King Squid and King Soup Squid are naturally included in the sperm whale's diet.
Although King Squid and King Sour Squid are both very big and long in length, a large proportion of their body length is tentacles, and their weight is not more than 1 ton, which is still a little smaller than that of sperm whales, so they are naturally no match for sperm whales. Scientists found an intact king squid in the stomach carrying the sperm whale. The body length of this king squid reached 12 meters and the weight reached 200 kilograms. Scratches similar to those of the king squid were also found on the mouth and body of the sperm whale. Based on this, we can infer that the king squid was eaten after fighting with the sperm whale. Some people speculate that sperm whales like to eat king squid and king squid mainly because they are invertebrates, have no bones, are delicious, and even have evolved excellent diving ability. You know, in the sperm whale's diet, bony fish only accounts for a very small proportion.
The largest squid
King squid?
King squid, to be precise, should be called King squid, not a squid, but a cephalopod mollusk of the family King squid and the genus King squid. It is the second largest member of Octopus, second only to Octopus, with a total length of13m and a maximum weight of 275kg. The body is conical, the back is suddenly thin and narrow, and the fleshy fin is short, which is located at the back of the coat and slightly peach-shaped; The myofilament of the oral membrane is connected with the dorsal margin of the fourth wrist; The funnel lock is oblong and straight. On both sides of the wrist sucker, the periderm is developed, and 4 pairs of male wrists are stylized; Touch wrist ten
Extended data:
life habit
Squid king is one of the species with weak swimming ability among oceanic cephalopods. Its funnel lock is simple and straight, its water spraying ability is weak, its fins are small, and its paddling ability is not great. The concentration of ammonia ions in the muscles of the head, trunk and wrist of the king squid is high, and the proportion of ammonia ions is slightly smaller than that of seawater, so it can obtain greater buoyancy. The pigment cells on the body surface, especially on the back, are well developed, and even the visceral surface has dark red pigment deposits. The expansion and contraction of pigment cells on the body surface make the body color change rapidly, which becomes a protective adaptability of squid.
The king squid feeds on other cephalopods and small fish. At the depth where the king squid inhabits, the only light comes from the bioluminescence of the organism itself, which is often the light emitted by bacteria carefully cultivated in the luminous organs in order to obtain light. Unlike whales living in the same depth, the king squid has huge eyes, so they are likely to use some visual functions when hunting.
