On June 8, The United Nations World Day of the Oceans, we know less than 5% about the oceans, and 4-5 new species of marine life are discovered by scientists every year.
Even if there is no sea around you, the sea creatures actually exist around us, to be precise: it exists in our stomachs: salmon, oysters, pippi shrimp, crabs, etc., are our common table objects. (Drooling indisputably...) ）
But do you know what exactly the oysters you eat are? What scallops and nails do you eat? Today, Xiaobian will take you to understand: the "marine animals" on the tip of our tongue.
<h1 class="pgc-h-arrow-right" > what are the iron plate squid, octopus balls, and cuttlefish balls? </h1>
Three major dishes for marine mollusks: octopus, squid and cuttlefish. Let's take a look at these three things now, what is the difference:
octopus
The octopus is considered to be the most intelligent of the invertebrates, and we are most familiar with the famous octopus Paul in football.
Paul the Octopus predicted the outcome of the European Championship and world cup, shooting as much as 90%.
There are as many as 252 species of octopuses in the ocean, and the octopus we usually eat is only one of them called the regular octopus (. vulgaris) species, octopus is larger, wild individuals are generally more than half a meter in length. The largest octopus found so far weighs up to 53.6 kg and reaches 15.6 meters in diameter after the brachiopod is unfolded!
With only 15 meters in length, this creature was destined to live in the vast sea, because there was simply no such space on land for them. The cold lesson worth knowing is: Do we think that the octopus's eight legs are used for walking?
In fact, when encountering danger, octopuses will more often put away 6 legs, and only use 2 legs to run on the bottom of the sea, because 2 legs they run faster.
In the snack streets of the city, we often see food made of octopus, such as the octopus balls you eat.
Octopuses like to hide themselves and have a penchant for "drilling utensils". Seaside residents catch octopuses, sink a large jar into the water, and after a while, the octopus will burrow in on its own.
squid
The most well-known is the teppanyaki squid, in the northern coastal city market, you will see a variety of dried squid, in fact, the squid we use is a species called "Chinese gun squid". But then you will know that although its scientific name is "Chinese gun squid", it is not what we usually refer to as squid.
Squid are easily distinguished from cuttlefish and octopus in appearance, because their bodies are cone-shaped, and you know just by looking at this shape: they must swim very fast.
The bigger difference between squid and octopus is that squid have more antennae, 10. This is what you see in the snack street:
cuttlefish
You rarely hear the name cuttlefish, but there is one snack you must have heard of, and that is "Flower Branch Ball". Cuttlefish are also known as flower branches. In terms of classification, cuttlefish and squid are listed in the "squid family", we usually say "squid", in fact, specifically refers to cuttlefish rather than squid Oh!
Cuttlefish appeared very early, 20 million years before the emergence of humans. In fact, the oldest cuttlefish have shells and bones, but now that they have degenerated, we can still see traces of the shell of the cuttlefish. If you look closely at the cuttlefish in the fish market, you will find that it still has a thin shell on its back.
Cuttlefish also have 10 "tentacles", 2 long ones called tentacles, and the other 6 wrists. Cuttlefish bone can be used in medicine, and cuttlefish meat is an excellent delicacy.
Cuttlefish, squid and octopus are the most common marine mollusk foods on the market. Let's sort out the differences between these three things:
octopus. It is what we usually call octopus, which likes to hide in the dark and loves to hide, and mostly lives below the shallow sea.
cuttlefish. It is what we call "Hanagi Maru" and "Squid", with ten tentacles and a larger body.
squid. Plate squid, dried squid, the main edible species of Chinese gun squid, small in size, cone-shaped. Happy bright, mostly in shallow seas. It is the best of the three. 10 antennae.
<h1 class="pgc-h-arrow-right" > what shellfish are you eating? </h1>
After introducing squid, let's take a look at what the shellfish we usually eat is. What exactly are scallops? What is a flower nail? What is oysters?
Oysters: This is the so-called oyster
Oysters are called "women's beauty salons, men's gas stations" but not blown, in fact, its scientific name is called "oysters", zinc content is currently the highest in food. Since ancient times, it has been recorded that oysters have the effect of lowering blood pressure and nourishing yin and yang. Its flesh can not only be eaten, but also the shell can be used for medicine.
China's history of eating oysters is 2,000 years old, and the popular bamboo oysters in the Han Dynasty are said to be oysters. As ordinary people, oysters are a delicacy, and for scientists, their medicinal value is far greater than their edible value.
In short, this thing is really good for the human body. However: it is also a carrier of norovirus and Vibrio cholerae, so eating oysters must not be eaten raw!
Clams and scallops
The scallops and clams we usually eat are actually two different families of clams: clams and scallops.
The most obvious difference in appearance is that the clams are oval and smooth in appearance, and the scallops have obvious concave and convex lines on the outside.
The "flower shell" we usually eat is the flower clam in the clam, which actually includes three varieties: Xishi tongue, four-horned clam and Chinese clam. So if you eat pollen in different places, you will eat shells that look different, which are actually "flower clams".
Scallops are more "expensive" than clams, and they are on a par with abalone and sea cucumbers. Sounds incredible? Tell you another name for scallops and you'll know how expensive they are: scallops are dried scallops.
Dried scallops with bear paws and deer tail tips!
Scallops are mainly farmed in the north, and the economic value is huge, mainly including ctenophore scallops, bay scallops and Ezo pan scallops as the main edible objects.
Garlic vermicelli scallops are a very noble dish!
In fact, animal knowledge in our lives is everywhere. For the oceans in particular, our human exploration rate is less than 5%. You can't imagine the magical life and phenomena in the ocean that is 10,000 meters deep.
The above foods have basically been successfully cultivated on a large scale and have entered every household. However, there are still people who wantonly hunt marine animals for the sake of greed.
Taking the opportunity of World Oceans Day on June 8, I would like to appeal to you: to protect the marine ecology is actually to protect ourselves.
