These three types of creatures, who are generally not well understood, are really unclear.

Many people think of cuttlefish and octopus as squid, and they are also marine mollusks.

The body structure is roughly the same. To distinguish them, you can only distinguish them from more subtle places.

They are also relatively expensive seafood products.

Today I will introduce you how to recognize the difference between squid and octopus squid.

First, the octopus has eight wrists with different body structures, and the squid and cuttlefish have ten wrists.

Octopus is soft, squid has cartilage, and cuttlefish has hard bones.

Second, the appearance and shape of the octopus can be seen. We can think of octopus balls-its body is sac-like, looks like a ball; squid’s body is narrow, like a pipe, and its cross-section is ring-shaped; cuttlefish’s body is larger and very large.

Third, different life habits. Octopus generally crawls along the bottom of the coast with a sucker in the wrist, and moves very slowly.

An octopus is a nocturnal animal-very sensitive to light-likes to stay in a dark environment, fishermen often toss special clay pots into the sea, and then calculate the time, please enter the 瓮-wait for the octopus to drill into the tank, and throw it inSquid and cuttlefish like to be bright, and the fisherman uses his habit to hang fish-collecting lights on the fishing boat and wait for them to swarm, and then wipe them out.

Fourth, different ways of eating octopus can be eaten raw or cooked, and raw food is particularly good; squid, cuttlefish should be cooked before eating-all because there is an alternative ingredient in the body-eat immediately if not cooked, often make diners gastrointestinal movementDisorders that cause abdominal discomfort.

In addition, aquatic products such as squid are cold in nature, and people with a cold stomach and spleen should also eat less.

First of all, let’s categorize and see at what level they started to split.

From the level of the class, the three species of octopus, squid, and squid are still a family. These are all belonging to the cephalopods Amaranthus (also known as the sub-branchs).

From the level of the order, the octopus belonged to the order of the order Octacarya, and the squid and squid belonged to the order of ten carapace, and the squid belonged to the order squid alone.

At the level of the family, the three organisms are completely distinguished. The octopus belongs to the octopus family, the squid belongs to the squid family, and the squid belongs to the calaquiidae.

The octopus realized from the above that we can grind it. The relationship between squid and squid is relatively close. Modern science also believes that squid and squid should be the same ancestor.

Next, let’s talk about the differences between the three. First of all, the octopus has a special habit, and they like to use their tentacles to suck at the bottom of the sea and slowly crawl.

Squid and octopus like dark environments, so they are often in deeper waters.

Squid Squid and squid have similar habits. Both of them like light, so they like to stay in shallow waters.

The speed of both of them is obviously faster than that of the octopus, and the ten tentacles can exert force at the same time, and they can move forward quickly in the sea.

In this way, we also mentioned above that octopus belongs to the order of the eight-armed order and squid and squid belong to the order of the ten-fisted order.

So the octopus has two fewer tentacles than squid and squid.

In addition, although octopus, squid, and squid belong to the mollusc phylum, octopus is the softest of the three.

Squids have cartilage in their bodies, and squids have hard bones in their bodies. Both of them replace “bone” than octopus.
