Is the ink sprayed by cuttlefish saliva? What is the function of a cuttlefish spitting ink?

No! The ink in the stomach of the squid is a kind of self-protection. Usually cuttlefish float in the sea and feed on small fish and shrimp.

If a fierce predator pounces on it, the squid immediately spews out a stream of ink from the ink sac, blackening the surrounding sea like smoke, and sometimes the smoke is shaped like itself, and it is easy to confuse the enemy, and it slips away in this black smoke screen. This ink of the squid also contains toxins, which can be used to paralyze predators, and even large fish lose their sense of smell and ability to discern directions in this liquid. Since it takes a long time for a squid to accumulate a bag of ink, it is reluctant to use ink unless it is in a desperate situation.

No, cuttlefish is a large carnivorous mollusk, and the reason why it is different from ordinary shellfish is that it has its own evolutionary process. Accustomed shellfish, because of the heavy shells on their backs, or buried in the tidal flats, or crawling on the rocky reefs, or attached to the sessile objects with foot filaments, waiting for the rabbit to filter feed on small zooplankton, the range of activity is very small, the movement speed is very slow; In order to take the initiative to plunder high-nutrient food, cuttlefish need more space to move, so after a long evolutionary process, the appearance has changed greatly. In order to adapt to swimming, its body gradually becomes oval and has a flat ventral dorsal; The shell degenerates into a calcareous plank, encased in an increasingly developed mantle, forming a carcass; When moving fast, there is no swing function of the tail fin of the fish, so the hydraulic principle is used to spray a column of water through the mouth to propel the body forward, and the swimming speed can exceed that of ordinary fish. In particular, when encountering an enemy, it will not only make a reverse escape movement like a rocket, but also cast a "smoke screen" to spray "ink" from the ink sac to create a barrier, confuse the opponent, and then flee; In addition, the "ink" contains toxins, which can be used to paralyze enemies and play a strong role in resisting enemies.

However, this kind of "ink" needs to be stored for a long time, so cuttlefish will not easily spray "ink" unless it is in a critical moment. Usually, when roaming, the cuttlefish generally relies on the wings and the wrists and feet of the head to make forward movements, which is not only a "two-way runner", but also a "reverse sprinter". Weird, you say, isn't it?

Because it swims like a fish and has an ink sac in its abdomen, coastal fishermen call it "cuttlefish", which is its common name; And its taxonomic classification of shellfish has a scientific basis. The basic structure of shellfish is: the body is soft, unsegmented or pseudo-segmented, and usually consists of five parts: head, feet, trunk (visceral sac), mantle, and shell; In addition to the flap gills, there are jaws and tooth tongue in the oral cavity; The nervous system includes ganglia, nerve cords, and a ring of nerves that surrounds the esophagus; The body cavity retracts into a pericardiac cavity.

According to this, the cuttlefish is, of course, a shellfish, it belongs to the phylum mollusks, cephalopods, decabrachidae, squid. It has three genera (Golden Squid: there are 9 species such as Golden Squid; Squid without needles:

There is only one species of squid without needles in China, and Zhejiang has the largest output; Squid genus: There is a posterior squid). The "cuttlefish" or "cuttlefish" referred to by our Wenzhou masses are mostly the two species of "Man's needleless squid" and "golden squid" produced in the East China Sea, which are their "honorable surnames".

There is little difference in the appearance of the two, the main differences are: the former carcass is oval, slightly thin, boneless needles, and the dried product is called "borer"; The latter has bone needles, and the dried product is called "dried squid".

You'll understand after reading it.

Evade enemy attacks. When the cuttlefish encounters a strong enemy, it will use "inkjet" as a way to escape and wait for an opportunity to leave, so it has names such as "squid" and "cuttlefish". However, this kind of "ink" needs to be stored for a long time, so the cuttlefish hail will not easily spray the "ink" unless it is in a critical moment.

The life habits of the squid are rockySquid like to live in the deep waters of the open sea. In the warm spring season every year, they swim from the deep sea to the shallow inner bay to lay eggs, lay eggs in April and June, adhere to seaweed and other objects, and start in late September, and the hatchlings of that year swim back to the south for wintering.

It can prey on crustaceans, molluscs and other small animals during migration.

Spraying ink is a cuttlefish's escape trick. When the cuttlefish encounters an unexpected situation in the mountains, envy or encounters enemies, the first thing it uses is to spray ink and lay ink smoke screens around itself.

Interestingly, the black smoke screen laid by the cuttlefish is very similar in shape and silhouette to its own body shape. Ink contains toxins that paralyze enemies. The sudden appearance of a black smoke screen can leave an impression on the enemy for more than ten minutes.

No matter how brave the enemy is, when he sees this situation, he will be inexplicable and at a loss. At this point, the cuttlefish can take the opportunity to escape the danger.

Interference threatens the sight of one's own creatures and keeps oneself safe, similar to smoke grenades.

The ink is usually stored in the squid's body, and when the squid is in danger, they release the ink. The ink is poisonous, paralyzing the enemy, and interfering with the opponent's sense of smell. Under the cover of ink, it is easier for squid to escape.

Translation: There is a creature in the sea, the size of a fist, called a cuttlefish. He has ink in his abdomen, and when he swims in the water, he uses the ink to cover himself, so fishermen often follow the ink to catch them.

Original text: The sea has insects thick and pure, and those who are alive with fists are called cuttlefish. There is ink in its belly, and when it swims in the water, it covers its body with ink, so the catcher often traces the ink and fishes it. Belch! He who deceived himself, why did he bring disaster upon himself? People have wisdom, and they are enough to learn.

Cuttlefish Profile:

Squid, also known as cuttlefish, cuttlefish, squid marine cephalopod mollusc, and octopus and spear squid are closely related. The modern squid appeared 21 million years ago in the Miocene, and its ancestors were arrowstones. It is characterized by a thick calcareous inner shell (squid bone, cuttlefish bone or sea cricket, which can be used as medicine).

The body of the squid can be divided into three parts: head, feet and torso, the trunk is equivalent to the visceral mass, and the outer body is covered with a muscular mantle and has an inner shell of calcareous trousers. The anterior end of the cephalic body is spherical, and its apex is the mouth, surrounded by oral membranes, and there are 5 pairs of wrists on the periphery. There are a pair of well-developed eyes on both sides of the head, and the structure is complex.

There is an oval-shaped fossa at the lower back of the eye, called the olfactory trap, which is the olfactory organ, and the olfactory apparatus of gastropods is a chemoreceptor.

Hello. Yes, cuttlefish has ink. The cuttlefish is a cephalopod with a surface covered with melanocytes, and when the cuttlefish feels dangerous or frightened, these melanocytes are agitated to release a black liquid called ink.

The main components of ink are melanin, a strong pigment that can be used for dyeing, and estradiol have certain antioxidant and anti-aging effects. Ink has a certain protective effect on cuttlefish, which can help cuttlefish confuse predators and hunt prey. In cooking, ink can also be used as a seasoning, such as to cook foods such as pasta, or to smoke foods to add texture.

Have a great day!

The ink of cuttlefish is edible. The ink of the cuttlefish is the base material released when it escapes from danger to turn the surrounding sea water black and confuse the enemy, and the introduction of eating cuttlefish rice in Jiangsu and Zhejiang is introduced. In foreign countries, health foods such as bread, cold powder, and surimi made by adding cuttlefish ink have been marketed.

The ink of cuttlefish contains a mucopolysaccharide, which has a certain anti-cancer effect. The ink of cuttlefish contains anti-cancer substances and is attracting increasing public attention. After processing, the ink of cuttlefish is a valuable medicinal material with a good hemostatic function.

Efficacy and function of cuttlefish juice: Cuttlefish juice is a self-defense substance spit out by cuttlefish when encountering natural enemies, which can affect or paralyze the intruder's sense of sight and smell. The main ingredient of cuttlefish juice is melanin, which is rich in fucose-rich polysaccharide-peptide complex, which has a good anti-tumor effect and is non-toxic, and its anti-tumor effect is due to the enhancement of immune system function, especially the result of enhancing cellular immune function.

Cuttlefish juice is regarded as waste in many places in China, but cuttlefish bile is a good thing abroad. Cuttlefish ink can be used to make cuttlefish inkItalian seafood noodles can be made into bread, ramen noodles are good, and so on.
