Squid What exactly is the difference between octopus and cuttlefish?

1. Different species: Octopus, commonly known as octopus, is a mollusk octopod octabrachio. Cuttlefish and squid are a type of fish with different names in different regions, and they are animals of the order Cephalopoda of the mollusc phylum.

Whereas, squid is a species of cuttlefish or squid. 2. The body structure is different: the octopus has eight wrists, while the squid and cuttlefish have ten wrists.

3. Different softness: the octopus has a soft body, the squid has cartilage, and the cuttlefish has hard bones.

Difference Between Octopus and Squid. For us, squid appears in front of me more in the form of a delicacy, its flesh is elastic and delicate, grilled squid is a delicious snack that often appears in our daily life. Another name for the squid is the nudibranch, and its body is pale in color with light brown spots on it.

Squid in our lives, it is also called cuttlefish. Squid, like squid, also have ten tentacles, but the octopus has a soft body and no cartilage, as mentioned above. The squid, on the other hand, has hard bones in its body, it is not as soft as an octopus, and its body is more qualitative than that of an octopus.

The white bones in the squid's body are due to the fact that the squid itself belongs to a type of shellfish, and with the evolution and purification of time, the shells in his body have degenerated and turned into white bones, which are the hard bones in his body mentioned earlier. The body of the squid is relatively flat, and it is particularly wide, which is actually very good to distinguish between squid and octopus from the appearance.

They are all mollusks, and they taste very similar when cooked, the squid is longer, the octopus is also called the octopus, and he has eight tentacles of basically equal length, and the cuttlefish has a flat and round body.

Squid and cuttlefish have 10 wrists and can swim freely in the sea, while octopus has 8 wrists, and octopus is also called octopus. Octopuses crawl slowly with suckers and cannot swim.

According to your description, squid and octopus are more similar, squid is slightly smaller, octopus is larger, and cuttlefish is more flat in shape.

Cuttlefish, octopus, octopus, and squid are the same species of fish.

Difference Between Squid and Octopus (i.e., Octopus, Squid, and Cuttlefish):

1. The families and genera are different.

Squid belongs to the family Gun Squid and is an animal of the Molluscosaurus phylum Cephalopoda Sheaquata, the Decabrachial General Order Squid, and the Eye-opening suborder.

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.

2. The shape is different.

The body of the squid is conical, pale, with light brown spots, a large head, 10 tentacles in the front, and a triangular fin at the end of the tail, and often swims in groups in the ocean at a depth of about 20 meters.

The octopus has an ovoid or oval body, strong muscles, a narrow opening in the mantle cavity, and generally no water holes on the body surface. 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.

3. Different living habits.

Squid is often active in the middle and upper layers of shallow water, and its vertical movement range can reach more than 100 meters. It feeds on krill, sardines, silverfish, small male fish, etc., and is itself the prey object of ferocious fish. The eggs mature in batches and are produced in batches, and the eggs are packed in a gelatinous egg sheath, and each egg sheath contains a few to hundreds of eggs depending on the species, and the number of eggs laid by different species also varies greatly, from hundreds to tens of thousands.

Octopuses are carnivorous and feed on gills and crustaceans (shrimp, crabs, etc.), with some species feeding on plankton. It's not a question of whether it likes it or not, because stable structural myoglobin is a necessary condition for octopus to survive in the deep sea, and it fights to the death with lobsters in order to compete for astaxanthin (ASTA) resources, astaxanthin is the strongest antioxidant, and it is necessary to ensure that the myoglobin structure is stable and not oxidized.

Squid, squid, cuttlefish, and small octopus belong to different categories of cephalopods, respectively.

Octopus, with eight tentacles, has a more rounded body.

The cuttlefish is a cuttlefish, with 10 tentacles, the squid is a kind of squid, also called the spear squid, the body is more slender than the general squid, and the end of the torso is as sharp as the head of a spear, so it is called the spear squid.

The specific performance is as follows:

1 Mantles are different.

Squid, octopus, and cuttlefish all belong to the cephalopod class, and the body can be divided into head, foot, and carcass, of which the carcass is the mantle.

The difference between its mantle is that the squid is cone-shaped, the octopus is spherical, and the cuttlefish is bag-shaped. The most commonly eaten squid, also known as the spear squid, has a pointed trunk like a spear.

2 Brachiopods are different.

Octopuses belong to the Octopus order and have eight relatively long brachiopods, so they are often called octopuses; Squid and cuttlefish, on the other hand, belong to the order of Ten Brachiae and have ten brachiopods, so they can be distinguished from octopuses by counting their feet.

As for squid and cuttlefish, some people think that it is the cuttlefish that can spray ink, and it is the squid that does not spray ink.

In fact, although the inkjet ability of squid is not as good as that of cuttlefish, it still has an ink sac.

3. The inner shell is different.

The most obvious difference between squid and cuttlefish is that cuttlefish has an inner shell, which is calcareous, and its scientific name is sea sheath, which is generally known as cuttlefish bone, which is also one of the commonly used medicinal materials in traditional Chinese medicine;

The inner shell of the squid, on the other hand, is thin and transparent, and the tail of the squid has a "bone" that resembles a plastic sheet. As for octopuses, their inner shells have completely degraded, so they have extremely high shrinkage skills and can drill in and out of very small holes.

Cuttlefish, squid, octopus are not the same thing. The cuttlefish is what we usually call the squid, and the octopus is an octopus, and they are still different from different animals.

Cuttlefish belong to the order Squid, squid belong to the order Tube Squid, and octopus belong to the order Octabrachia; Cuttlefish, also known as squid, will escape by "inkjet" when encountering strong enemies; The squid, also known as the sea hadibranch, has ten tentacles on the front; The octopus is called an octopus and has eight tentacles.

The squid, also called the nudibranch, has a conical body, a pale body with light brown spots, a large head, 10 tentacles in the front, and a triangular fleshy fin at the end of the tail.

The squid's real name is cuttlefish, also known as flower branches, cuttlefish, or cuttlefish, and squid is a branch of squid. Squid is an animal of the order Cephalopoda of the mollusc phylum Cephalopod. When a squid encounters a strong enemy, it will use "inkjet" as a method of escape and wait for an opportunity to leave, so it has names such as "squid" and "cuttlefish".

There are small pigment sacs in its **, which will change color and size with the change of "mood".

One big difference between cuttlefish and squid is that it has a wider body and an extra hard shell on its back.

Octopuses have soft bodies, squid have cartilage, and cuttlefish have hard bones.

The octopus body is short ovate, sac-shaped, and finless; The head and body are not clearly divided, and the octopus has a large compound eye and 8 retractable wrists on the head about centimeters.

They are completely different animals, although there are some similarities that some people may not be able to tell the difference, but they are not the same thing.

A lot of people can't tell the difference between squid, octopus and cuttlefish. I couldn't tell the difference, so let me share with you how I did it today.

Squid is not a fish, it is a mollusk in the ocean, it has a very high nutritional value and is very common in life. For example, shredded squid, grilled squid, sizzling squid and so on. Its color is pink to flesh, then it has a very long body shape, and then it has several long claws.

Octopus, as the name suggests, it has eight claws, its head is small, but the eight claws are thin and long, and the color is also flesh pink, it is not a fish either, it is a mollusk in the ocean. If the octopus and the squid are compared in appearance, the octopus head is small and round, and the octopus head is long and wide. And it also has a special ability to defend itself and attack.

I think the braised pork stew with octopus is so delicious!

Next, let's talk about cuttlefish. Cuttlefish, also known as cuttlefish, is not a fish, but a mollusk in the ocean. When the cuttlefish encounters a strong enemy, it will spray ink and randomly flee from danger.

And it also has pigment sacs in its body, and the color is changing, not static. Its body is between an octopus and a squid.

If you distinguish them according to their body shape, the squid has the largest body and has a wide and long head, while the claw fish has a small head. The claws are long and small. Cuttlefish have neither long nor short heads and also have claws. The size is somewhere in between. Then the cuttlefish's special skill is inkjet.

Actually, I want to distinguish something or something. Let's start by understanding their essence. They are then analyzed. Find out what they have in common, and then find out what they are different about, and you can get the answer we want.

In fact, these three animals are very delicious to process, for example, I like the sizzling squid the most, the squid is really fragrant, chewy, and the shredded squid is milky and fragrant. Octopus stew with sauerkraut, I can eat several bowls of rice. Cuttlefish can be stir-fried casually and become a food to accompany rice.

That's all for my personal experience.

If you want to distinguish this squid, I think it's easy to distinguish it from the octopus, and I think they taste different.

In fact, the difference between the squid and the octopus and the cuttlefish is still very big, first of all, if you hesitate, its breathing is relatively long, and now there are a lot of claws, and the octopus, its claws are open in all directions, but in the case of cuttlefish, it has only one claw, so their form is still very different.

The squid has long whiskers and a small head, while the octopus has eight claw heads of normal size, and cuttlefish can emit large ink heads. Squid is more common, and cuttlefish generally have black ink.

Squid is flat, octopus has 8 claws and has a strong suction, while cuttlefish is inkjet.

Octopus is a general term for invertebrates under the order of the kingdom of organisms, molluscs, cephalopods, subclasses, octopus, and octopus, also known as crickets, octopus, octopus, etc., with more than 280 species in more than 30 genera and 13 families in the world, widely distributed in the tropical, tropical and temperate waters of the Pacific Ocean, Indian Ocean and Atlantic, and the representative populations are true clams, short clams, long clams, North Pacific giant octopus, blue-ringed octopus, etc.

Squid is a general term for invertebrates under the order of organisms, molluscs, cephalopods, subclasses, decabrachies, gunniformes (tube squid), also known as soft fish, gun squid, etc., two suborders of closed eyes and open eyes suborder under the order Gunformiformes, of which the closed eyes suborder are collectively referred to as the squid, and the open eye suborder is collectively referred to as the soft fish, there are about 29 families, 300 genera and more than 300 species in the world, and the representative populations are Chinese squid, Pacific folded squid, king squid, king squid, etc.

Squid is a general term for the invertebrates under the order of biological kingdom, molluscs, cephalopods, subclasses, decaephalopods, and squid, also known as cuttlefish, cuttlefish, branches and leaves, etc., widely distributed in the world's oceans, the key lives in shallow water along the tropical and temperate coasts, and often migrates to deeper waters in winter, and the representative populations are golden squid, needle squid, fine squid, mansoni needleless squid, spotted squid, etc.

Cuttlefish has a wide range of carnivorous habits, usually using small shrimp as the key food, fish as the secondary food, and is not picky eater. There are many baits used as bait, such as long-arm shrimp, grass shrimp, shrimp girl, etc. are ideal bait, and fatty pork, salted fatty meat, and Xiaoxia auxiliary gods can also be used as bait. If there is no real bait, use the aluminum and platinum in the cigarette box package to make fish-like bait, and the fishing effect is also very good.

In addition, plastic and wood bait can be used. Cuttlefish mostly move in groups, and if you catch one in a certain water layer, it is likely to be a group, so you should seize the time to take the bait.

Cuttlefish often use their tentacles and suction cups to catch bait, but the moment they are lifted out of the water, they will immediately release their tentacles, unhook and escape, so they cannot lift the cuttlefish out of the water after catching it, and must use a net to catch it before going out of the water. Cuttlefish instinctively squirt ink when they are too frightened, so after catching the cuttlefish with a net, let it spray the ink in the net, and then catch the fish and board the boat to prevent the ink from being sprayed on people.

Octopus is actually just another name for octopus, squid and cuttlefish belong to the same order, and squid and cuttlefish are the same creature. When fishing for these fish, you can put some meat on the hook.

The size is different, the shape is different, the color is different, and most of them are salvaged when they are collectively salvaged.

The half-shapes are not the same, they belong to different varieties, and this is generally fished out with a net in most cases.
