Is cuttlefish the same as octopus? What's the difference between them? The family practice of Douyu with ink

Someone asked,"Are ink fishes the same as octopus?" What's the difference?" First of all, we have to make it clear: ink squid is cuttlefish, and octopus is octopus, so we only need to distinguish between Chu cuttlefish and octopus.

Cuttlefish is also called white squid, cuttlefish, cuttlefish, or cuttlefish. Like squid, it also has ten feet. Unlike squid, cuttlefish has a ship-shaped hard calcareous sheath, which is the "sheath" on the back that looks like bone and is not too hard. Squid's biggest feature is that it will encounter strong enemies "inkjet" as a way to escape, waiting for the opportunity to leave, so there are "squid","cuttlefish" and other names. There are pigment sacs in the skin that change color and size in response to "mood." Cuttlefish are generally used for large roast, braised.

Octopus is also called octopus, stone house, sitting octopus, stone suction, watch tide, dead cow, belongs to mollusc phylum cephalopod octoptera. Octopuses have eight arms with suckers; sometimes they release black ink to aid in escape. Some octopuses have fairly developed brains that can distinguish themselves in mirrors. In terms of cooking method, octopus meatballs are a well-known delicacy.

Cuttlefish and octopus have something in common:

1, their ancestors are nautilus, belong to the mollusc cephalopod, although called "fish", in fact, not fish, no fish characteristics.

2, their appearance is very similar, are streamlined, symmetrical left and right, head connected to the carcass, so called cephalopod. Around the head and mouth are eight arms (cuttlefish and squid have two longer tentacles), which are soft and elastic, and each arm has a suction cup on the inside.

The difference between cuttlefish and octopus is:

Cuttlefish has 10 arms, octopus has 8 arms, and the shell of cuttlefish is a hard calcareous sheath, while octopus does not.

2, octopus commonly known as eight belts, there are eight slender claws, claws have a lot of strong suckers, belly is round, can spray ink, general food is shellfish; cuttlefish body oval, there is a hard shell inside, can also spray ink, generally eat small fish shrimp.
