What are the characteristics of squid, what are the living habits of squid?

Squid 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.

Predation characteristics: Because stable structural myoglobin is a necessary condition for the survival of the squid in the deep sea, the squid is keen to eat crabs, fish, shellfish, and even the king squid does not hesitate to fight to the death with the sperm whale, just to compete for astaxanthin (ASTATHIN, ASTA) resources. Astaxanthin is the strongest antioxidant and is necessary to ensure that the structure of myoglobin is stable and not oxidized.

According to Professor Francesco Buda, a scientist at Leiden University in the Netherlands in 2008, and his experimental team members, it was found that the reason why cooked shrimp, crab, salmon as the representative fish, and some shellfish meat showed an attractive bright red color through accurate quantum computing methods was because shrimp, crab, salmon as the representative fish, and some shellfish meat were rich in astaxanthin, and the natural red substance of cooked shrimp, crab, salmon as the representative fish, etc. was astaxanthin.

Food: Squid mainly eat crustaceans, small fish, or other mollusks. The main predators are large aquatic animals.

The ink in the squid's body is usually stored in the ink sac in the stomach, and when it encounters an enemy attack, they will spew a stream of ink from the ink sac, staining the surrounding sea water black, and then take the opportunity to escape.

Squid have the habit of changing their color by adjusting the size of the pigment sac in their body in order to adapt to the environment and escape predators.

Squid they live in dark and damp places, basically on the bottom of the sea, some squid are very large, they are very dangerous, we must be careful not to have contact with them when we go to the beach.

The difference between a spear squid and a squid is as follows:

1. Gun squid.

Spear squid, also known as squid, also known as soft fish, often moves in the middle and upper layers of shallow seas, and can move vertically up to more than one meter. The spear squid mainly feeds on krill, sardines, silverfish, small male fish, etc., and is itself a predator for fierce fish. The meat of the spear squid is delicate, and the dried product is called dried squid.

2. Squid. Squid is also known as cuttlefish, cuttlefish, squid and octopus and spear squid. Squid generally live in shallow waters along tropical and temperate coasts, and often migrate to deeper seas in winter.

The common squid breeds in spring and summer, and the squid mainly eats crustaceans, small fish, or eats each other. The main predators are large aquatic animals, the meat is edible, the ink sac can be used to make ink, the meat is delicious and nutritious.

Features of the spear squid and squid

1. Appearance characteristics.

Squid are mollusks and are close relatives of spear squid and octopus. The ancestor of the squid is an arrow stone, and there is a very thick calcareous inner shell on the body, which is also called squid bone, Mo Changming Bi fish bone or sea clam, which can be used as a medicine guide. The whole body of the squid is divided into a head, torso, and feet, among which, the torso resembles a mass of internal organs.

The outside is a muscular mantle, and the inside is a lime shell.

2. Habit characteristics.

Squid like to live on the bottom of the open sea, and every year in the spring, when the climate warms up, Jeanmen begins to swim to Repulse Bay, where they lay eggs and reproduce. The eggs stick to other objects such as seaweed, and by late September, they begin to hatch and swim back south to prepare for the winter. On their way back, they will forage for crustaceans and other molluscs.

Squid, also known as cuttlefish, is a cephalopod that lives in the deep ocean. It has a funnel on its head, which is not only an outlet for reproduction, excretion, and ink, but also an important locomotor organ. When it tightens its body, the water in its pocket-like body can spurt out of the funnel and move forward quickly with the help of the reaction force.

Since the funnel usually always points forward, the squid retreat is moving forward. <

Squid, also known as cuttlefish, is a cephalopod that lives in the deep sea of the pelagic section. It has a funnel on its head, which is not only an outlet for reproduction, excretion, and ink, but also an important locomotor organ. When it tightens its body, the water in its pocket-like body can squirt out of the funnel rapidly, and it moves forward quickly with the help of the reverse pin.

Since the funnel usually always points forward, the squid retreat is moving forward.

Problem description: Please, the practical value of squid. Very useful.

Analysis: Squid can be said to be a treasure all over the body, delicious to eat, and good medicinal effect. What is commendable is that it combines the gastronomy function of food with the function of medicine and health care.

According to the traditional concept of Chinese medicine in China, there can be two kinds of treatment: medicinal therapy and dietary therapy, and dietary therapy is to combine the gastronomic function of food with medicinal value, which is not only in line with the traditional medical concept, but also close to the concept of modern health food.

There are many ways to eat squid, such as cold dressing, stir-fried mullet shreds, fried mullet rolls, roasted mullet soup, mullet fillet, etc., especially braised mullet meat with fresh garlic, the taste is extremely delicious. Its eggs are roasted into fish gelatin, and then by the hands of the chef, it becomes a well-known and high-quality delicacy at home and abroad. In addition, the internal organs of squid can be pressed to make visceral oil, which is a good raw material for tanning.

Its eyeballs can be made into eyeball glue, which is a high-grade glue and agent.

Although both spear squid and squid are common seafood, there are some distinct differences between them.

1.Living environment and range of activity: The spear squid lives in the middle and upper layers of shallow seas, and can move vertically up to more than 100 meters. Squid, on the other hand, usually live in shallow waters along tropical and temperate coasts, and often migrate to deeper seas in winter.

2.Food Ignition Core: The gun squid mainly feeds on krill, sardines, silver squid, small male fish, etc., and is itself a predator for fierce fish. Squid, on the other hand, mainly eat crustaceans, small fish or mutual carp.

3.Breeding Methods: Gun squid breed in spring and summer. Squid, on the other hand, breeds in spring and summer.

4.Nutrients: The meat of both squid and squid is rich in nutrients, but the specific nutrients of the two types of seafood differ.

Overall, gun squid and squid differ in terms of living environment, range of movement, food, reproduction methods, and nutrient content.

Gun squid: Gun squid is also known as sentence gong, soft fish, squid. The spear squid is an animal of the mollusc phylum Cephalopod Tube Squid Eye-opening suborder, with a slender body and a long cone, with more than a dozen tentacles.

Two of them are long, with suction cups at the front of their tentacles, and tooth rings inside the suction cups, which are entangled around their tentacles to swallow when they hunt for food. Prefer to live in groups, especially during the mating and spawning period in spring and summer; Squid: The name of the sock is the squid, also known as the flower branch, cuttlefish or cuttlefish, is an animal of the order Cephalopoda Squid of the mollusk phylum.

When the squid encounters a strong enemy, it will use inkjet as a method of escape and wait for the opportunity to leave, so it has the name of black thief, cuttlefish, etc. There are small sacs of pigment in it, which change color and size with changes in mood. Squid leaps out of the sea in a disgraceful way, has an amazing ability to fly through the air, and is a marine mollusk like squid and octopus, none of which are fish.

There are about 350 species of squid: needle squid, golden squid, spear squid, needleless squid, flame squid, fluorescent squid, king squid, spotted squid, fine squid, flying squid, etc., the smallest of which is the young squid.

Classification Subject: Phylum Mollusc.

Giant squid: On January 16, 2014, Japanese biologists went through 1,000 voyages and more than 400 hours of diving and search missions with NHK and Discovery Channel (Discovery) to photograph this precious ** in the sea at a depth of 630 meters.

The "giant squid" is about 8 meters long, and this is the first time that humans have photographed it in its natural habitat.

The National Museum of Science and Science of Japan was in charge of the shooting, and the team members also included NHK and Discovery.

Tsunemikubodera, a squid expert involved in the project, said they followed the behemoth to the bottom of the sea at a depth of 900 meters before watching it continue to the deeper canyon in the sea. From the **, we can find that this giant squid is shining all over its body, and its eyes are clearly visible, but the longest 2 tentacles are missing.

On January 21, 2014, Tsunashiro Shinko in Iwami Town, Tottori Prefecture, Japan, caught a giant squid with a length of 100 kilograms, weighing 100 kilograms, and up to 8 meters in length if its longest tentacles remained. ”
