What is the difference between squid, octopus and squid?

Squid, octopus, and squid are often indistinguishable because they have similar tentacles. Interestingly, all three animals belong to the class Cephalopod, the phylum Mollusca.

Although octopuses, squids and squid all have pigment cells, octopuses are relatively much more exciting than the latter two, the latter two are usually single discoloration, and octopuses will mimic sea snakes, anemones and other creatures to scare off enemies. <>

These three types are commonly found in both wet and seafood markets: octopus, squid, and squid. Squid and squid are actually the same family of squid, and what we often call eye fish and cuttlefish is actually talking about one thing, that is, squid.

All three kinds of fish can spray ink, and the fried small tube we often eat is actually fried squid. The squid has a javelin-like, streamlined, slender head with ten legs. <>

Next is the octopus, the octopus has a round head with eight legs, and some seafood markets have live octopus for sale, indicating that the octopus goes out to sea and can survive for a while on land where there is water. Have you seen live squid and squid? Octopuses can also quickly change their color, and can also disguise themselves in the form of some fish, which is very magical, of course, the octopus is mainly eaten by boiling!

Finally, there is the squid, which has an oblong head with a skirt distributed throughout the head, also ten legs, and is rich in ink. Squid in nature can instantly change their color and blend in with their surroundings. The tastier way to make squid is stir-fried with leeks.

How to distinguish: 1. Look at the mantle all three belong to the cephalopod class, and the body can be divided into head, foot and carcass. Among them, the carcass is the mantle, which has three forms, the octopus is spherical, the squid is bag-shaped, and the squid is cone-shaped.

Second, look at the wrists and feet.

1. Octopuses have eight relatively long brachiopods, and the third wrist on the right side of most male octopuses is specialized as a handsome wrist, or genital wrist.

2. Squid and squid have about ten symmetrically arranged brachiopods, counting from the dorsal side to the ventral side, and the fourth pair of wrists is relatively long, and the end is swollen like antennae, which is called "tentacle", which is also a handover wrist.

3. Look at the suction cups.

1. 2 or 1 row of suction cups on the octopus brachiopods, without a stalk and ring, and will not be specialized into hooks.

2. The squid's wrist suckers have 4 rows, and the tentacle spike suckers have several rows to dozens of rows, with handles and rings.

3. Squid, that is, the species of the gun-shaped order, have more than 2 rows, and the tentacle wrist suckers are mostly 4 rows, with stalks and rings with small teeth, and some types of suckers are specialized into hooks.

4. The tentacles of squid and squid are important in hunting, and the wrists and feet of octopuses are also very powerful. If tentacles are known for their explosiveness, then the octopus's wrists and feet are won by skill.

Fourth, touch the inner shell.

This involves the legendary "bones" of squid, but how can mollusks have bones, in fact, this is its inner shell, I believe that friends who have dealt with squid have seen it.

1. The inner shell of the octopus has degenerated, so they have a strong ability to shrink bones.

2. The inner shell of the squid is, thin and transparent.

3. The inner shell of the squid is well developed and calcareous, which is called the sea clam.

You may have eaten a lot of snacks made of cuttlefish, squid or octopus, such as cuttlefish noodles, shredded squid, charcoal-grilled octopus, etc. Now what you see on ** is the ** of these three animals.

However, let me ask you a question, can you distinguish between the three animals of cuttlefish, squid and octopus? Many people can't tell the difference between them. It's no wonder, after all, they look so similar.

If it's made into a dish, it's even more indistinguishable! But that's okay, today I'm going to teach you how to distinguish between cuttlefish, squid and octopus.

In terms of biological classification, these three animals belong to the same class, called the cephalic class, and the animals in this classification have their heads and feet growing together. Here's what they have in common.

How can you tell the difference? First of all, we can look at the number of brachiopods, that is, the number of feet. Octopuses have eight brachiopods, as you may have heard, octopuses are also called octopuses, and that's how the name comes from.

Cuttlefish and squid, on the other hand, have ten brachiopods, eight of which are short and two are long, so the octopus can be found by counting its legs.

So how do you tell the difference between cuttlefish and squid? To distinguish between them, you have to go by the number of suction cups. Cuttlefish and squid have small, round suckers on their wrists and feet that they can attach to other objects through which they can be attached.

The cuttlefish has more suckers, with 4 rows of suckers on its eight short brachial feet and more on its two long brachial feet, which is generally much better. Squid, on the other hand, have fewer suckers, generally only 2 rows of suckers on short brachiopods and 4 rows of suckers on long brachiopods. If you look closely, there are also small serrations on the squid's suckers.

You see, count the feet first, and the one with eight legs is an octopus, and the one with ten legs is a cuttlefish or squid. After counting the feet, I looked at the suckers on the feet, and the suckers were more cuttlefish, and the squid was less squid, which distinguished them.

But hearing this, you may have to ask, Lao Liu, this method you taught is too troublesome, is there an easier way? There really is.

In fact, we can also distinguish them by the shape of the carcass. The carcass is the month word side plus an identical same. The carcass is also called the mantle, which is the part of their body that looks like a sleeve.

If the shape of the carcass is round and spherical, it is an octopus; If the shape of the carcass is flattened, like a bag, it is cuttlefish; The carcass of the squid is a pointed cone.

Finally, I would like to say that some students may also ask about another common animal, the squid, which is actually the cuttlefish, which is another name for the cuttlefish. Okay, how's it going, have you learned? The next time you go to the Clan, you can learn and tell who they are!

The octopus has 8 legs, the squid and the squid have 10 legs, the squid will spray black silk ink, and there is a hard bone in the body, the octopus has an oval body, and the squid has a longer body and a cartilage in the body.

The squid is slender and long, and its small head is pointy.

The octopus has a round head and has 8 tentacles.

The squid, also known as the cuttlefish, spits ink when it is threatened.

Squid and octopus are animals of the same class, similar but different in size, and octopuses are relatively short and round. The number of feet varies, with octopuses also called "octopus" and squid 10. Squid, also known as soft fish, spear squid.

Squid meat is more delicious than cuttlefish. The head and torso are narrower than those of a cuttlefish, especially the end of the torso resembles the head of a javelin, hence the name squid.

The appearance of the three is similar, the body shape is different, in terms of nutritional value, squid is good for blood and kidney, squid has the effect of preventing anemia and liver detoxification, octopus can resist fatigue and is suitable for malnourished people.

Their body structure is different, the octopus is 8 wrists, while the squid and squid are both 10 wrists The octopus is softer, and both the squid and the squid have bones, and their appearance and shape are also different.

As far as the appearance is concerned, it can be distinguished by four aspects:

1. The appearance and shape are different, 2. The degree of softness and hardness of the body is different, 3. The number of tentacles is different, and 4. The ink bag is different.

For example, in terms of appearance, an octopus looks like a small ball, while a squid looks like a tube, and a squid moves like a net.

In terms of shape, a normal octopus is spherical and has eight legs, while a normal squid is a long tube with ten legs and no ink bag; A normal squid is flat in shape and has ten legs.

There is a difference in the shape of the head and the number of feet. In the shape of the head, the squid is cone-shaped, the octopus is spherical, and the cuttlefish is bag-shaped; Octopuses have eight relatively long brachiopods, while squid and cuttlefish have ten brachiopods.

What is the difference between an octopus squid and a squid.

Octopus: that is, the octopus that everyone often says, its characteristics are very obvious, that is, it has eight wrists, thick and powerful Squid, formerly known as squid, also known as branches and leaves, cuttlefish or cuttlefish, is a small animal of the order of the mollusk phylum Cephalopoda Squid. When the squid encounters its opponent, it will use an inkjet printer as a way to escape The squid has cartilage and eight legs, and it is usually eaten on the street with a white belly.

The difference between the three creatures can be distinguished by the antennae, the octopus has 10 antennae, the squid and the squid have only 8 antennae, the squid's head is bag-shaped, and the squid's head is cone-shaped.

The octopus has eight wrists, and the squid and squid have ten wrists. Octopuses have soft bodies, squids have cartilage, and squid have hard bones.
