How to distinguish between octopus, squid and cuttlefish?

Octopus sashimi, squid strips, cuttlefish stewed with chicken soup, these are all delicacies that food lovers love to see, but if you only look at the pictures of the actual creatures, they are all big eyes and soft tentacles, and most food lovers probably can't call out their names at once. In addition, these three marine creatures have many nicknames, such as squid, calamari, cuttlefish, octopus, etc., which is inevitably dazzling. I don't know which fish it is and I lose the argument. Let's carefully distinguish the differences between these three delicious ingredients.

octopus

First of all, judging from the names, octopus's nickname is octopus, squid's nickname is calamari, and cuttlefish's nickname is cuttlefish, squid... well, this point seems to have no meaning in distinguishing them, so let's skip it.

squid

Secondly, from the perspective of biological taxonomy, octopus, squid and cuttlefish all belong to the phylum Mollusca - Cephalopoda. The most distinctive feature of cephalopods is that their legs grow on their heads, which are represented by funnels and arms (which we usually call tentacles). Among them, octopus belongs to the order Octopoda of the cephalopoda, while squid and cuttlefish belong to the order Decapoda of the cephalopoda. In other words, by counting the number of tentacles, you can roughly distinguish octopus from the latter two cephalopod brothers.

Cuttlefish

Finally, from the appearance, the bodies of octopus, squid and cuttlefish can be divided into three parts: head, foot and mantle. The mantle of octopus is spherical, that of squid is cone-shaped, and that of cuttlefish is bag-shaped. Squid is more slender than cuttlefish, and the end of its mantle is like the tip of a javelin, so it is called a squid. If you still can't tell squid and cuttlefish apart, you can try pressing the middle of their bodies. The soft one is squid, and the harder one is cuttlefish, because the inner shell of squid is keratinous and thin, while the inner shell of cuttlefish is calcareous. As for octopus, its inner shell has completely degenerated, so it has superb "bone shrinking" skills.

Octopus and octopus are the same;

Octopus cannot be said to be the same as squid. It can only be said to be a type of squid, characterized by its small body and slender trunk. It is also called softfish.

Squid, cuttlefish and octopus all belong to the class Cephalopoda of the phylum Mollusca

Squid, also known as cuttlefish and calamari.

Cuttlefish, also known as cuttlefish and squid, belongs to the same order as squid.

The meat of squid is more delicious than that of cuttlefish. Its head and trunk are narrower and longer than those of cuttlefish, especially the end of the trunk is very similar to the tip of a javelin, so it is called squid.

Octopus, also known as octopus, belongs to the order Octopoda.

Both octopuses and cuttlefish have ink sacs that release ink. The biggest difference is that octopuses only have 8 arms, and the suction cups on their arms have no handles or tooth rings.

The distinction is quite simple. Regardless of whether the vendor uses ink to fake the goods, you can make a relatively accurate distinction by paying attention to the following points about the leather fringe.

Cuttlefish - short in body, with a spindle-shaped, slightly flat bone in its abdomen called Wuchantou (called Haipiaoxiao)

Squid--It is longer than cuttlefish, has no hardware bones, only two long, plastic-like tubes.

Cuttlefish and squid of the same weight are longer than cuttlefish; squid is one-fourth to one-fifth longer than cuttlefish. When cut open, the meat on both sides of the cuttlefish is wider than that of the squid.

I wish you good luck! I hope I can help you. Please accept my answer! Good people will have a peaceful life!
