Some animals are colorblind, but there are also many animals that see the world in color. This color is different from the color in the eyes of humans. Many animals can see much more colors than humans. There are many wonders in the world. Some animals are colorblind and see the world in black and white (such as dogs). Some animals have as many as thousands of compound eyes (such as bees). Some animals are blind to static objects (such as frogs). Some animals have ultra-high resolution eyes (such as eagles). Some animals have a 270-degree field of vision (such as geckos). There are countless.

The colors of objects seen in the eyes of animals are the same as those of humans?

Not necessarily. There are differences in the perception of color between animals and humans. Human eyes can perceive the seven colors of red, orange, yellow, green, blue, indigo and violet in the visible spectrum. This is because there are three types of cone cells in the human eye, which have different sensitivities to different wavelengths of light, allowing us to see rich colors.

And animal eyes are very different in shape and structure. Some animal eyes are simpler than human eyes, with only one or several visual pigments. For example, dogs and cats have only yellow visual matter, which can perceive yellow and blue, but cannot distinguish between red and green. The eyes of some insects contain as many as 30 different types of visual pigments, and they can perceive near-infrared and ultraviolet light far beyond the range of human vision, so the perception of color may be more rich and complex.

Therefore, the color of objects seen in the eyes of animals is not necessarily the same as that of humans, and specific things need to be studied and experimented on different animals.

What animal can see everything behind without turning its head??

Chickens, pheasants, eagles, etc. in birds, their eyes are on both sides of the head, and their field of vision is relatively large, allowing them to see behind without turning their heads.

So you will find that when you approach a chicken from behind, it is already ready to escape.

A mathematical genius in the animal world?

Bees – “Genius Designers”

Have you ever looked closely at the structure of a hive?

It looks very beautiful and tidy, and the hive built by worker bees is also very wonderful. It is strictly hexagonal. It has a hexagonal opening at one end and a closed hexagonal pyramid at the other end, composed of three identical rhombus shapes. Some people even call the hive a strange building in nature, and the ability of bees to build hives makes many architects feel “ashamed”.

Experts have specifically measured the size of a large number of beehives. It is very surprising that all obtuse angles of the diamonds that make up the chassis of these beehives are 109 ° 28 ′, and all acute angles are 70 ° 32 ′.

Later, mathematicians calculated theoretically that if you want to consume the least amount of material, the regular hexagon has the largest area, which can store more honey. For the mathematical talent of bees, we have to express our heartfelt admiration.

Ants – “Mathematical Wizards Who Can Multiply and Divide”

Young people, when you see ants moving, will you also lie on the ground and watch for a long time?

The calculation skills of the inconspicuous ants are very good.

British scientists once did an interesting experiment: cut a dead grasshopper into three pieces, the second piece was twice the size of the first piece, and the third piece was twice the size of the second piece. Forty minutes after the colony found these three pieces of food, there were 28 ants gathered in the smallest grasshopper, 44 in the second piece, and 89 in the third piece. The latter group was almost twice as large as the previous group. It seems that the multiplication and division of ants are quite good!

Not only that, but when ants are looking for food, they can always find the shortest route to food. It is amazing that the ants’ calculation skills are so accurate!

Coral polyps – “Little Calendar Master”

Coral polyps show their extraordinary mathematical talent in another way, they can magically write down “calendars” on themselves. Every year, 365 ring patterns are “carved” on their body walls, apparently one “draw” a day.

Some paleontologists have found that 3. Coral polyps 500 million years ago “drew” 400 ring patterns a year. Astronomers tell us that a day on Earth at that time was only 21.9 hours, which means that the year at that time was not 365 days, but 400 days.

It can be seen that coral polyps can “calculate” and “record” the time of a year according to the changes of celestial phenomena, and the result is quite accurate, which is really amazing!

Spider – “Geometry Expert”

I’m not talking about Spider-Man, the superhero who can spin silk!

The geometric pattern of the octagonal shape of the spider knot is complex and beautiful. This “gossip web” is difficult to draw like a spider knot web with a ruler and compass.

When analyzing this beautiful structure mathematically, the concepts that appear on the spider web are amazing – radii, strings, parallel line segments, triangles, congruent corresponding angles, logarithmic spirals, catenary lines and transcendental lines, it’s super amazing!

Red-crowned Cranes – “Precision Protractor”

Red-crowned cranes always fly in groups and line up in the shape of “people”. The angle of the “person” shape is 110 degrees. More precise calculations also show that half of the angle of the “person” shape – that is, the angle between each side and the direction of the cranes is 54 degrees 44 minutes and 8 seconds! And the angle of the diamond crystal is exactly 54 degrees 44 minutes and 8 seconds! Is it a coincidence or some kind of “tacit understanding” of nature?

The natural world is full of magic and wisdom, and there are many interesting things waiting for us to explore and discover, so we need to learn the basics and have a solid grasp, apply mathematics to our interesting exploration and discovery of nature, and we need to live in harmony and friendship with nature and love the wonderful world we live in together!
