Last Updated: 2026/07/15, Coffee is one of the important production tools in human society. There are tens of thousands of kinds of coffee with different flavors. Some people are fascinated by the unique flavor of coffee, while others are just to refresh their minds. In the eyes of many people, after drinking coffee, the central nervous system becomes excited, more alert, and thinks more clearly.

Coffee is one of the important production tools in human society. There are tens of thousands of kinds of coffee with different flavors. Some people are fascinated by the unique flavor of coffee, while others are just to refresh their minds.

In the eyes of many people, after drinking coffee, the central nervous system becomes excited, more alert, clearer and more focused. However, the above conclusion is that coffee only has an effect on humans. Due to the different body structure, coffee has many magical and even dangerous effects on different plants or plants.

In the late 1940s, Swiss pharmacologist Peter N. Witt studied the effects of drugs on spiders, used a series of psychotropic drugs on spiders, and observed the spider web patterns woven by spiders after using drugs.

When the spider ingested 10 micrograms of caffeine, the web was smaller and the radius was uneven, but the regularity of the circle was not affected. When spiders ingest 100 micrograms of caffeine, the shape of the web changes dramatically and becomes very irregular. In 1995, a research team of NASA in the United States repeated Witt's experiment and got similar results.

Spiders are invertebrates, and the nervous system of invertebrates is not as complex and diverse as vertebrates. From the previous conclusion, we can see that the effect of coffee on the nervous system of invertebrates may be fatal, and caffeine has a destructive effect on some enzymes in the nervous system. Some scientists served the larvae of a common diamondback moth with strong tea and coffee, and the larvae died within 24 hours.

The researchers repeated experiments with pure caffeine and concluded that caffeine was the cause of this result. As one of the invertebrates, caffeine is equally lethal to mosquitoes that humans hate. When mosquito larvae ingest high doses of caffeine, they become so incongruous that they cannot swim to the surface and drown.

For vertebrates, coffee is not very friendly. Many cat slaves and dog slaves themselves have the habit of drinking coffee, but they also try their best to keep their pets away from the sober elixir of coffee, avoiding caffeine intake by cats and dogs, resulting in significant changes in heart rate and respiratory rate, even death. For many animals, caffeine is difficult to metabolize and is life-threatening.

Of course, not all animals are life-threatening after consuming caffeine, and some animals, like humans, enjoy the positive effects of caffeine. In horse racing, caffeine plays the role of a "stimulant". When the horse ingests caffeine, its heart rate increases significantly, showing extraordinary endurance, jumping ability and speed, and its fatigue is reduced. As a result, caffeine has become an illegal drug in horse racing.

Bees, as a kind of invertebrates, like humans, like to drink coffee. In 2021, the Guardian reported that a study by the Institute of Natural Resources at Greenwich University in London found that bees pollinated more efficiently after consuming caffeine.

Coffee is one of the most popular drinks in the world, and human beings have been drinking this drink for a long time. The body structure of each species is different. Coffee contains thousands of chemicals, and when it enters the body, the chemical reactions are also very complex. So far, scientists are still exploring the effects of coffee on a variety of organisms.

Even so, it cannot resist the submission of human beings to coffee. So, did you have coffee today?
