Octopus sashimi, shredded squid and stewed chicken soup with cuttlefish are all favorite foods for food lovers, but if you only look at the actual biological pictures, they are all big eyes and soft tentacles. It is estimated that most food lovers can't name them at once. In addition, these three kinds of marine life have many flower names, such as squid, cuttlefish, cuttlefish, octopus, etc., which are hard to avoid dazzling, and I don't know what this fish is. Let's take a closer look at the differences between these three delicious ingredients.

Octopus

First of all, from the name point of view, octopus is alias octopus, squid is alias cuttlefish, and cuttlefish is alias squid and cuttlefish ... Well, it doesn't seem to make sense to distinguish them, so let's skip it.

? Squid

Secondly, from the taxonomic point of view, octopus, squid and cuttlefish all belong to the mollusk phylum Cephalopoda. Cephalopods are characterized by their feet born in the head, showing funnels and wrists (also known as tentacles). Among them, octopus belongs to Octopoda of Cephalopoda, while squid and cuttlefish belong to Decapoda of Cephalopoda. That is to say, counting the number of tentacles 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, feet and mantle. The mantle of octopus is spherical, the squid is conical, and the cuttlefish is bag-shaped. The squid is more slender than cuttlefish, and the end of the mantle looks like the spear head of javelin, so it is called cuttlefish. If you still can't tell squid from cuttlefish, you can try to press the middle of their bodies. The soft one is squid and the hard one is cuttlefish, because the inner shell of squid is horny and thin, while the inner shell of cuttlefish is calcareous. As for octopus, its inner shell has been completely degraded, so it has superb "bone shrinking" skills.
