There are also many mysterious mathematical "geniuses" in animals, and their skills are great!

Honeycomb is a strictly hexagonal cylinder, with a flat hexagonal opening at one end and a closed hexagonal cone bottom at the other end, which is composed of three identical diamonds. The rhombic obtuse angle of the chassis is 109 degrees 28 minutes, and all acute angles are 70 degrees 32 minutes, which is both firm and material-saving. The honeycomb wall thickness is 0.073 mm, and the error is very small.

Red-crowned cranes always migrate in groups. They always form a herringbone. The angle of the herringbone is 1 10 degrees. More accurate calculation also shows that half the angle of herringbone, that is, the included angle between each side of herringbone crane group and the forward direction of crane group is 54 degrees, 44 minutes and 8 seconds! And the angle of diamond crystal is exactly 54 degrees, 44 minutes and 8 seconds! Is this a coincidence or some kind of "tacit understanding" of nature?

The spider's gossip web is a complex and beautiful octagonal geometric pattern. It is difficult for people to draw a pattern as symmetrical as a spider's web even with the compass of a ruler.

In winter, kittens always hold their bodies together when they sleep, and there is also "learning" in the meantime! Because the sphere minimizes the surface area of the body, it also gives off the least heat.

The real "genius" of mathematics is coral. Coral writes a "calendar" on its body, and "draws" 365 stripes on its wall every year, apparently one a day. Strangely, paleontologists found that corals 350 million years ago "painted" 400 watercolors every year. Astronomers tell us that at that time, the earth only had 2 1.9 hours a day, not 365 days a year, but 400 days!
