Every evening, there are a lot of people walking around the lake. The pavilions along the road and on the island are lit up like a fairy tale world. When the musical fountain sounds, the whole night is brilliant and dazzling.
The busy spiders between the cracks of each guardrail are like a gorgeous dress under the light. Walking, square dancing, boating, playing musical instruments, singing people have their own free, daytime I do not know where to hide the spider unusually active, jumping in their own world, organized and leisurely to enjoy the spoils of capture.
There are many different kinds of spiders, 45,000 have been discovered, and the number of spiders is even more astonishing, there are one hundred trillion spiders of all kinds on Earth, and the number of spiders is 15,000 times the population of the Earth.
If you add up the weight of all the food eaten by the entire population of spiders in the world in a year, it is more than the total weight of every person on the planet. Biologists calculate that spiders around the world prey on insects weighing between 400 and 800 million tons per year, which is more than some massive animals like whales eat.
The total weight of what spiders prey on each year is about the combined weight of meat and fish food consumed by humans each year. This means that spiders eat at least as much meat as the world's 7.5 billion humans, who together weigh less than 300 million tons.
That means if spiders could eat people, the world's spiders still wouldn't be full after eating everyone. Spiders aren't just satisfied with insects, they often have a few vertebrates to add to their diet.
In Florida, a jumping spider that eats lizards and frogs is a spider that feeds primarily on insects. But more than 90% of the spider's diet consists of insects and jumping insects.
Because spiders swallow hundreds of millions of tons of small pests, spiders play an important role in maintaining the natural ecological balance system. It's the spider that hides in the corner that is the unabashed eater. This is only a small part of the overall food chain. In addition, spiders themselves are prey in the eyes of other species.
The survival of the fittest is the survival of the fittest, and in order to survive, intelligence is derived, and with intelligence, survival is guaranteed. Tiny spiders survive on Earth for hundreds of millions of years, and most spiders live only one year. In their short existence they do not leave any stone unturned.
