What are the functions of the tentacles of the octopus, and why are they said to be very powerful?

Octopuses have many tentacles and have many suction cups on them to facilitate their movement, and the upper suction cups can help them catch their prey more quickly when catching them. When in danger, when the tentacles are caught, they will directly cut off one of their tentacles, and then take the opportunity to escape.

Their tentacles play important roles, such as assisting in movement, predation, defense, etc., and each of their eight tentacles has a secondary brain that can be connected to the memory system. They have many suction cups on their tentacles and have the ability to adsorption.

The tentacles of the octopus are lined with suction cups, and these suction cups do not only generate suction, but also recently found that these suction cups may also contain cells that can process touch and taste signals. In other words, the "hand" of the octopus is also the "mouth".

That's right.

This tentacle is called the handover wrist hectocotylus. During mating, the male octopus injects the sperm bag into the mantle cavity of the female octopus by handing over the wrist. This wrist is often the third right tentacle and is characterized by a groove in the anterior segment without a suction cup.

Octopus Profile:

Octopus (octopus): is the common name for 252 species of marine mollusks in 26 genera of the octopus family. It is the largest family of cephalopods, which can be divided into bathypolypodinae, eledoninae, graneledoninae and octopodinae.

The body is ovate or oval, muscular, the mantle cavity has a narrow opening, and the body surface is generally without water holes. Wrist suction cups 1 or 2 rows. The third carpal stemmed on the left or right side of the male, with a seminal groove on the ventral margin of the wrist and a spoon-shaped lingual lobe at the end; The stemmed wrist cannot be self-broken.

Funnel jacket lock degraded. 1 pair of vestigial needle-like inner shells or no inner shells. If there is a toothed tongue, the teeth on the side of the tooth tongue are usually single-cuspid.

The stomach and cecum are located at the back of the digestive glands.

This family is an important commercial cephalopod, with some production of the true clamour (common octopus) along the southern coast of China and the brevis on the northern coast. The dried products of the mussel are called "dried eight mussels" or "dried octopus", in addition to eating, it also has the effect of nourishing blood and invigorating qi and astringent muscles in medicine.

It is a temperate mollusk, living underwater, adapting to the water temperature can not be lower than 7, the specific gravity of seawater is the most suitable, and the environment with low salinity will die. It can feed on large animal plankton and grow. It is widely distributed in tropical and temperate seas of the world's oceans.

Scientists have found that octopuses are a very intelligent species, and it can be said that they are also cunning and treacherous. That's why we say that the octopus is a very "brainy" animal. Because in many cases, the octopus does not rely on its own brute force to win.

This is because the nerves in the tentacles of the octopus are still alive, so they still squirm, so this is a very normal phenomenon.

The octopus is a cephalopod, and its tentacles have many nerves that cause muscles to contract, just like a person who is cremated before death, he will suddenly sit up because of the voluntary movement of the nerves.

Because the tentacles of the octopus still have some nerves, which can control the contraction of the octopus's claws, and the muscle tissue still retains a certain degree of mobility, so even if it is cut open, its claws will still move.

Octopuses have 8 tentacles, which is why they are called "octopuses". Each of their eight tentacles has a secondary brain that connects to the memory system. They have many suction cups on their tentacles and have the ability to adsorption.

Their tentacles are very strong and can regenerate after they are broken. Their tentacles play a very important role, such as assisting in movement, predation, defense, and so on. <

Octopuses are creatures that live on the bottom of the sea, but they are not fish, but mollusks. They have many special structures on their bodies, such as they have multiple memory systems, multiple hearts, and so on. Another special construct is their tentacles.

Octopuses are also known as octopuses, which are actually named after the number of tentacles, which means that they have 8 tentacles. These tentacles usually have suction cups on them, which are easy to observe.

As already mentioned above, the octopus has 8 tentacles. In addition, the role of octopus tentacles is very important. Octopuses generally stay in one place on the ocean floor for a long time without moving their position.

However, when it comes to moving their position, tentacles can play a very important role. In addition, these tentacles can also play a role in protecting themselves. For example, when their tentacles are bitten by an enemy, they will simply cut off one of their tentacles, and then run away while the enemy is unprepared, and their tentacles can be regenerated.

Furthermore, when predatoring, the role of tentacles is irreplaceable. They usually have a number of suction cups scattered on their tentacles, sometimes in number of hundreds or even hundreds. As a result, they have a very strong adsorption effect.

Researchers have done special research on the tentacles of octopuses, and found that although their tentacles have an adsorption effect, they will not suck into their own bodies. This strong adsorption will only suck the prey over quickly, and then these tentacles will wrap the prey tightly, making it impossible to breathe and unable to break free. This way the prey will soon die because it cannot breathe.

The octopus eats its prey only after it dies.

The tentacles of the octopus are both hands and feet, because they use their tentacles to absorb other objects and move, and the tentacles act as feet. However, when they catch food, they use their tentacles to put their prey into their mouths, and the tentacles act as hands. In addition, when the prey struggles, they will use their tentacles to tighten the prey until the prey suffocates to death.

Octopuses have 8 tentacles with suckers on the tentacles, and they use these suckers to move and hunt. <

The tentacles of the octopus are both hands and feet as their tentacles can be used as both hands and feet. When they move, they will use their tentacles to suck out other objects, and then complete the movement, at which point their tentacles are the function of their feet. However, when octopuses are hunting, they will stretch out their tentacles to grab their prey, and they will also use their tentacles to tighten their prey until the prey suffocates to death.

At this point, their tentacles are the function of the hand. Therefore, the tentacles of the octopus can be used as both hands and feet. Octopuses have 8 tentacles, each with two succulent suckers that they rely on to move and feed.

1. Movement: As mentioned above, the tentacles of octopuses can help them move. When they want to move, they will use their tentacles to suck in distant objects and bring their bodies over.

2. Predation: The tentacles of octopuses also have a predatory effect, and they have many suckers on their tentacles. When hunting, they will suck other animals tightly and then wrap their extra tentacles around the octopus to prevent the prey from breaking free.

3. Escape: When the tentacles of the octopus are bitten by other animals, they will directly cut off one of the tentacles, and then flee quickly while the enemy does not check. Octopuses' severed tentacles have the ability to regenerate, so their ability to escape is also very strong.

The octopus in the ocean has 8 tentacles, and each of them has 1-2 rows of fleshy suction cups, so it is also called an octopus. There are many varieties of octopuses, and the length of the tentacles varies depending on the species. The tentacles of short crickets are generally about 12 centimeters, the tentacles of long moths are generally centimeters, and the tentacles of real moths are about centimeters.

Octopuses usually use their tentacles to move, and sometimes they swim with the help of tentacles. <

The octopus in the ocean has 8 tentacles, and each tentacle has 1-2 rows of suction cups, so the octopus is also called an octopus. The octopus's tentacles still have the ability to regenerate after they are broken, but there is a stemmed wrist that cannot be broken by itself. Since there are many varieties of octopuses, their tentacle lengths are also different.

The tentacles of short clams are usually about 12 centimeters, the tentacles of long crickets are generally about centimeters, and the tentacles of real crickets are usually centimeters. The tentacles have a great effect on the octopus, and they rely on the tentacles for their usual predation and movement.

1. Predation: Octopuses mainly rely on tentacles to hunt, they have a relatively high IQ, and they will hide by changing the color and structure of their bodies. When they spot their prey, they quickly reach out their tentacles and hold them tightly.

2. Movement: The tentacles of octopuses can also help them move, and when they move, they will use their tentacles to support them. Some octopuses will also suck their tentacles onto other objects and then move their bodies over them.

In addition, there are some octopuses that swim in the water with the help of tentacles.

3. Survival: The tentacles of the octopus can also help them escape, if other creatures bite the tentacles of the octopus, then the octopus will cut off the tentacles by itself, and then escape while the enemy is unprepared. Their tentacles also have the function of regeneration, so if they are caught, there is a good chance that they will be saved by cutting off their tentacles.

There are many animals in the animal kingdom, including octopuses, that have an autotomy. Animals break off parts of their bodies on their own to escape predators during fights, but sometimes they do so to attract mates. This kind of behavior is terrifying, but it is also understandable for survival.

When biologists first saw these tentacles missing octopuses, they thought they were the result of self-cutting behavior.

But, curiously, these octopuses with missing tentacles all die within a few weeks. Any serious injury can lead to the death of an animal, and not every survival strategy is effective in the long term. Scientists, pet lovers, or aquarium staff often see their octopuses lose their tentacles.

It has been observed that the octopuses missing their tentacles do not self-cut, but instead eat their own tentacles. Autophagocytosis is not a survival strategy. Why do they do this?

Initially, the perception was that the lack of food caused the octopus to eat its own body. Aquarium biologists believe that under their care, it is unlikely that the octopus will have a shortage of food. In order to verify this, some people put more food on it.

As a result, the octopus's autophagophagocytosis behavior did not stop. So, is it because the octopus is bored or stressed? Stress caused by space constraints causing them to self-devour?

However, despite the measures taken, even to isolate them from the crowd, their self-devouring behavior has not stopped. And, in fact, as soon as a new octopus comes into contact with an octopus that has already been devoured by itself, the behavior spreads.

At the moment, the best guess is that this behavior is actually the result of contracting some kind of disease – although it is not yet understood. The infection invaded the octopus's nervous system, causing the octopus to devour itself in this horrific way and eventually kill itself.

When the octopus is attacked, it is forced to break its tentacles and escape, just like the gecko.

So far, no one knows for sure that this behavior takes place. The octopus devours its own tentacles because winter is coming, and in the case of food scarcity, eating its own tentacles is guaranteed.

When the tentacle is trapped or when you are in trouble, you should bite off.

This is used to escape at a critical moment.

In times of danger, of course, it is important to save your life.

For example, when he wants to run for his life, he will bite it off.

This is needed to save lives.

Break your tentacles and run away, just like geckos.

Eight. The octopus is a mollusk that lives on the bottom of the sea, and has many special structures on its body, such as multiple memory systems and multiple hearts. There is also a special structure that is the tentacles.

Octopuses have a nickname called "octopus", which is named after the number of tentacles they have, and they have 8 tentacles. These tentacles usually have suction cups on them, which are easy to observe.

An octopus can spray ink 6 times in a row, while an octopus that has finished spraying ink only needs to wait for half an hour to respray ink. Secondly, octopuses have an amazing ability to change color. The octopus has many highly developed pigment cells under the mantle that contain fluids of different colors, and the organs that direct the discoloration of the body are its eyes and cerebral spinal cord.

When frightened or angry, they can quickly change their body color, and through mimicry, sometimes disguised as a bunch of coral, sometimes disguised as a stone covered in seaweed. They can change color even when they are physically injured. Finally, the octopus's ability to escape can also help them run rampant in the ocean.
