Octopus is octopus, cuttlefish and mullet are squid!

Squid

Squid, though traditionally called fish, is actually not a fish, but a mollusk living in the ocean. Taxonomically, squid belongs to mollusk phylum-Cephalopoda-Diptera-Decapoda. Squid has two gills as respiratory organs; The body is divided into head, short neck and trunk. There are a pair of developed eyes and wrist feet around the mouth on both sides of the head.

At present, there are two kinds of squid in the market: one is a squid with a large trunk, and its name is "Squid"; One is a squid with a slender trunk. Its name is "Soft Fish", and the small soft fish is commonly called "Small Tube Boy".

Octopus

Octopus, like squid, is a cephalopod, because its feet are born on the top of the head. However, it only has eight feet, and there is no foot that is specially used to catch food like squid. Its eight feet are very long, like eight belts, so fishermen call it "octopus".

Octopus is also a fierce animal. There is a big sucker with strong suction on its feet. If we catch a small octopus and hold it in our hand, it will immediately suck our hand with a sucker, and it will be very difficult to take it off!

Octopus also has ink sacs in its body, and the ink contained in it also contains toxins, which can be used not only to defend against enemies, but also to attack them. An interesting fact is that when the octopus is resting, it doesn't rest all together, but leaves one or two long feet on duty and keeps turning. Although its body and other feet feel dull, if it touches its duty foot slightly, the octopus will jump up immediately and release thick ink to hide itself.

Because octopus has powerful feet, sucker and good defense tools, animals of the same size in the ocean will be harmed by it. Even the largest and best-equipped crayfish, although about the same size as octopus, will inevitably become its victim.

Octopus is very fleshy, and it is also an excellent seafood.

The local names of Octopus biology are Changzhang, Brachiopoda, Zuoyi, Shixi, Wangchao, Zhanggan, Octopus vulgaris, Octopus in English and Octopus in Japanese, belonging to invertebrates, mollusca, Cephalopoda, and Octopus. Both the north and south coasts of China are distributed. The fishing season is divided into spring and autumn, and spring is from March to May. September-November in autumn.

Octopus is short oval with no fins. There are 8 wrists on the head, so it is also called "octopus". Wrists are connected by membranes, which are equal or unequal in length; There are two rows of sucker without handle on the wrist. Most of them live in sandy gravel or soft mud bottom and rocky reefs in shallow sea, and they are carnivorous, feeding on cladocera and crustaceans. In late spring and early summer, I like to lay eggs in snail shells, so I can use a rope to penetrate the red snail shells and sink to the bottom of the sea to extract and catch them on time. In autumn and winter, they often burrow in the sediment in deep waters. The common octopuses in China are Octopusochellatus, Octopusvariabilis and Octopusvulgaris. The head and trunk of octopus are about 7 ~ 9.5 cm. The wrist length of octopus is about 12 cm, that of octopus is about 48.5 cm, and that of octopus is about 32.5 cm. Usually crawl with your wrist, sometimes swim by stretching the membrane between your wrists, or use the funnel at the bottom of your head to spray water for quick retreat.

squid

squid belongs to invertebrate mollusks. Among marine creatures, the squid swims fastest, and its swimming speed is very fast. Unlike ordinary fish swimming by fins, it advances rapidly by the reaction of water spraying from the funnel pipe on its belly, and its spraying ability is like rocket launching. It can make the squid jump from the deep sea and jump out of the water as high as 7 to 1 meters. Squid's body is like a cannonball, and it can fly about 5 meters in the air. The speed of squid swimming in seawater can usually reach more than 15 meters per second, and the maximum speed can reach 15 kilometers per hour. The swordfish, known as the champion of swimming speed among fish, has a speed of only 11 kilometers per hour, so it has to admit defeat. Of all the squid in the world, the youngest is the baby squid. Its length is no more than 1.5 cm, which is about the size of a peanut and weighs only .1 g. This subminiature squid lives in the aquatic plants in the shallow sea of Japan, and its appearance is very similar to that of ordinary squid, except that there is a sucker on its back, which can be adsorbed on the aquatic plants and will not be washed away by the sea. Usually, it rests on the aquatic plants. Once it finds its prey, it suddenly attacks. After eating, it returns to the aquatic plants to rest quietly, waiting for the next prey. The biggest squid in the world is the king squid. They generally live in the depths of the ocean, rest in the deep sea during the day and swim to the shallow sea for food at night. In the kingdom of squid, there is also a small firefly squid. It is a luminous creature, with three light-emitting devices on its belly and one around some eyes. The light it emits can illuminate 3 cm away. When it meets a natural enemy, it emits strong light, scaring the natural enemy into running away.

squid can be said to be a treasure all over the body, which is delicious to eat and has good medicinal effect. What is commendable is that it combines the delicious function of food with the medical and health care function. According to the traditional concept of Chinese medicine, there are two kinds of treatment: drug therapy and dietotherapy, and dietotherapy is to combine the delicious function and medicinal value of food, which is in line with the traditional medical concept and close to the concept of modern health food.

There are many ways to eat squid, such as cold salad, stir-fried shredded mullet, fried mullet roll, fried mullet soup, sliced mullet, etc. Especially, the mullet braised with fresh garlic moss is very delicious. Its eggs are baked into fish glue, and then cooked by the chef, it becomes a famous fine food at home and abroad. In addition, the viscera of cuttlefish can be squeezed into viscera oil, which is a good raw material for tanning. Its eyes can be made into eyeball glue, which is the first-class glue and agent.
