Spider is a famous geometer, and its "gossip net" is complex and beautiful. This symmetrical octagonal geometric figure is difficult to draw even by senior carpenters with rulers and compasses. Coral, known as "algebraic genius", writes a "calendar" on itself: it "carves" more than 300 patterns on the body wall every year. Ant is a great computing expert. The British scientist Hinston did an interesting experiment: he cut a dead grasshopper into three pieces, the second piece was twice as big as the first piece, and the third piece was twice as big as the second piece. Forty minutes after ants discovered these three foods, the first grasshopper gathered 28 ants, the second grasshopper gathered 44 ants, and the third grasshopper gathered 89 ants, the latter group was about twice as many as the former group. It's amazing that ants have such high computing power. Bees, great architectural experts. The beehive built by bees is hexagonal, and the angle is very accurate. This structure not only saves materials, but also is strong and solid, which is really wonderful.
