The difference between octopus, cuttlefish, squid and squid

These creatures are all mollusks, and they all live in the sea. They are all rich in nutrients and are precious seafood ingredients, and are very popular among people. Many times people mistake octopus and cuttlefish for squid, and sometimes it is even difficult to distinguish the taste. So today I will tell you the differences between octopus, cuttlefish, squid and squid.

First of all, their body structures are different. The octopus has eight arms, while the squid and cuttlefish have ten arms. The octopus has a soft body, the squid has cartilage, and the cuttlefish has hard bones. Second, their appearances and shapes are different. Usually, the body of an octopus is sac-shaped, resembling a meatball, while the body of a squid is long and narrow, like a tube, and its cross-section is ring-shaped. The body of a squid is relatively flat and very wide. Third, their living habits are different. Octopuses usually crawl along the seabed using the suction cups in their arms, and their movements are very slow; squids and cuttlefish swim quickly in the sea. Octopuses are nocturnal animals, and are very sensitive to light, and like to stay in dark environments. Fishermen often throw special pottery jars into the sea, and then calculate the time, waiting for the octopus to get into the jar and fall into the trap; squids and cuttlefish like light, so fishermen take advantage of their habits and hang fish-attracting lights on the fishing boats, waiting for them to swarm in, and then catch them all in one net. Fourth, the way of eating is different. Octopus can be eaten raw or cooked, and it is better to eat it raw. Squid and cuttlefish must be cooked before eating, because there is a polypeptide component in their body. If it is not cooked thoroughly before eating, it will often cause gastrointestinal motility disorders and abdominal discomfort. In addition, aquatic products such as squid are cold in nature, so people with weak spleen and stomach should eat less of them. Fifth, now you should have a basic understanding of the basic characteristics of squid, octopus and cuttlefish! No more worrying about mixing them up.

Note: Squid and cuttlefish must be cooked before eating, because there is a polypeptide component in them. If it is not cooked thoroughly before eating, it will often cause gastrointestinal motility disorders and abdominal discomfort. Cuttlefish, also known as cuttlefish, has a white body and does not have an arrow-shaped tail fin behind its body compared to squid. The pipe octopus is a slender cuttlefish, also known as the pen pipe octopus, small squid, and black octopus. From the appearance, it is a cuttlefish with a slender body. The pen fish is nicknamed the sea hare squid, which is the calamari. Because its hair is generally red, it looks very similar to a squid, but is also larger and longer, with an arrow-shaped tail fin at the back. In addition, two of the squid's ten tentacles are particularly long. Octopus is a kind of octopus. The key difference between it and cuttlefish and squid is that octopus has 8 legs, while cuttlefish and squid have 10 legs. In terms of size, the squids sold in the market are generally larger than cuttlefish and octopus. Octopus is the smallest. After being cooked, the squid is usually red. Octopus, squid and cuttlefish are jokingly called the "Soft Three Brothers". Many people cannot distinguish them clearly and confuse them. In fact, it is easy to distinguish them if you master the rules:

The difference between octopus, squid and cuttlefish is that they are delicious but also need to be distinguished (squid) 2. Different appearances and shapes When we see octopus, we can think of octopus balls - its body is sac-shaped, resembling balls; the squid's body is long and narrow, like a tube, and the cross-section is ring-shaped; the cuttlefish's body is relatively flat and very wide. The difference between octopus, squid and cuttlefish is that they are delicious but you have to tell them apart (cuttlefish) 3. Different living habits: Octopus usually crawls along the seabed using the sucker in its arms, and its movements are very slow; most octopuses crawl along the seabed using their suckers, but when frightened they will spray water from their body tubes with strong force, causing them to move quickly in the opposite direction. Squids and cuttlefish swim quickly in the sea. Octopuses are nocturnal animals and are very sensitive to light. They like to stay in dark environments. Fishermen often throw special clay pots into the sea, then calculate the time and lure the octopus into the trap - waiting for the octopus to get into the pot and fall into the trap. Squid and cuttlefish, however, like light, so fishermen take advantage of their habits and hang fish-attracting lights on the fishing boats, waiting for them to swarm in, and then catch them all in one net.
