2. Why do bullfrogs croak after it rains?
The phenomenon of bullfrogs chirping after rain is not accidental, but is closely related to the following scientific principles:
1.reproductive behavior: Bullfrogs chirp mainly to attract the opposite sex. The increase in humidity after rain creates a more suitable breeding environment for frogs, so the frequency of chirping increases significantly.
2.air pressure changes: Changes in air pressure before and after rainfall stimulate the bullfrog's auditory system, thereby triggering its vocal behavior.
3.ambient humidity: The skin of bullfrog needs to be kept moist, and the high humidity environment after rain makes it more active.
4.food chain reaction: Insect populations increase after rainfall, with bullfrogs calling to announce their territory and attract prey.

4. Expert interpretation and hot discussion among netizens
Professor Wang from the Institute of Zoology, Chinese Academy of Sciences, said: "The bullfrog's chirping after the rain is the result of a combination of its biological clock and environmental factors. This phenomenon is especially obvious in tropical areas."
Netizen "Nature Lover" commented: "Every time it rains, you can hear the chorus of bullfrogs. It turns out this is their blind date meeting!"
The video "Decrypting the Bullfrog's Call" released by the short video creator "Science Explorer" received 2.3 million likes and became this week's popular science content.
5. Extended thinking: the delicate balance of the ecosystem
This phenomenon reminds us to pay attention to the impact of climate change on animal behavior. According to the latest research, the breeding period of bullfrogs has advanced by an average of 15 days in the past 10 years, which is consistent with the trend of global climate warming.
Protecting biological diversity is not only to maintain the balance of nature, but also for the sustainable development of human beings. The bullfrog's cry may be nature's signal to us.
Conclusion
Starting from a small natural phenomenon, we see the exquisite design of the ecosystem. Next time you hear the cry of bullfrogs after the rain, you might as well listen to this symphony from nature and think about the true meaning of harmonious coexistence between humans and nature.
