Whether it's lying in a beach tent with a gentle sea breeze or sitting on a seat at a roadside barbecue stall, taking a bite of freshly baked grilled squid is one of the best memories of summer. For foodies like me, squid may seem like a familiar delicacy, but how much do you know about the roots of life behind it? Today to talk to you about the overseas media in recent years to pay attention to the report of squid news, the most eye-catching is that the squid squid family is likely to be from a distant foreign visitor.
Squid is known as the "manta ray" in South America. Its large eyes and glowing structure of its body are indeed very rare compared to other creatures on Earth, and the deep-sea squid in adventure movies and TV dramas often play a strange devil role. It seems to go along with these claims.
Among the invertebrates of the vast ocean, squid have the highest learning and memory ability. According to a paper published in the Academic Journal of the National Academy of Sciences in 2020, marine giant squid actively transmits information to each other through the changes of more than a dozen stripes on their bodies, coordinates and cooperates with the division of labor, and completes the attack and sharing of prey in groups.
In addition, studies have shown that the brain of squid has a larger number of nerve cells relative to its body size. Two-thirds of these cells are in turn distributed in the tentacle area. Each tentacle is like a supercomputer operating independently, and can perform its own completely different actions at the same time. Imagine that it is difficult for us humans to do it: at the same time, we direct our left and right hands to do different things, which is incomparable with squid.
The squid has the same one-eye structure as humans, its vision is equivalent to about 0.6 degrees of ours, its eyes are the same as ours, it has the function of lens focus, and can see higher resolution objects. This feature is also very useful when defending against enemies or catching prey. If we follow the ratio of squid eyes to body, our human eyeballs need to grow to the size of a basketball. Squid's eyes grow on either side of the head, and there are no blind spots at all, which is far superior to humans with a combined viewing angle of about 130 degrees. If you look for their shortcomings, it is a little regrettable that the image seen by the squid is always black and white, without any color.
The viewing field of the squid's eyes: three hundred and sixty degrees without dead angles
Squid's great features are:
Has three hearts. The main heart is responsible for transporting blood throughout the body. The other two hearts, also known as gill hearts, act like pumps blood into the gills and swims quickly with the gills.
Superhuman's movement speed. The maximum swimming speed of squid is about 41 km / h. Bolt at his peak (theoretical speed of 39 kilometers per hour) could not catch up with it, and conversely, once he was targeted by squid, even Brother Bolt could not escape.
Bolt: Actually, I can't keep up with the speed and I can't shake off a squid...
More and more overseas researchers believe that it is likely that in a certain historical period, extraterrestrial microorganisms (viral cells) from space fell into the earth's ocean, and then the yin and yang were mistakenly combined with the organisms that have inhabited the seawater to form a new genetic body, and after experiencing a unique evolutionary process, a family of squid (squid including octopus) was born. If these assumptions hold true, then deep in Earth's oceans, there appear to be more and larger squid organisms lurking. Perhaps they have already built their own underwater world, society and civilization in places that are out of reach of human beings. They have lived on Earth and coexisted peacefully with everyone for many years, and even have been continuously transmitting information to their home planet in the depths of outer space.
The more I knew, the more I felt that I didn't dare to eat squid casually... But reason is really difficult to overcome appetite, and at the same time as paying the highest respect to [the squid passes through the intestines, the Buddha's heart stays], I pick up the chopsticks [than the heart]
Home cooking Whole body squid dried in a pan
Live sashimi is one of the best in the world
Squid tempura is not less than one bite
