In nature, life may appear calm, yet it is constantly a struggle between survival and death. Powerful species may go extinct in a short time, while seemingly weak ones manage to survive tenaciously. About 60 million years ago, a planetary impact struck the Earth, triggering earthquakes and tsunamis and pushing the planet into a cold ice age. For years or even decades, there was no sunlight, and the world was plunged into darkness.
The dinosaurs, then the dominant creatures on Earth, relied on their strength and hunted other animals aggressively amid the chaos. However, in the dark environment, it was difficult to distinguish prey from their own kind. In the confusion, many species perished, and the number of dinosaurs gradually declined.
The remaining dinosaurs had to expend enormous energy to hunt. Even when they caught prey, the energy gained was not enough to compensate for what they spent during the chase. The hungrier they became, the more fiercely they ran and pursued, continuously draining their strength, eventually leading to their extinction.
Surprisingly, their relative—the crocodile—survived in such harsh conditions. Although smaller and not as powerful as dinosaurs, crocodiles were able to catch a wide range of fast-moving animals, including fish, water birds, and even monkeys and leopards.
This is because crocodiles employ highly strategic hunting methods. They often remain motionless, like a log floating on water, exposing only their nostrils and eyes while patiently observing their surroundings. Once prey is detected, they silently slip into the water, slowly approach the target, and then suddenly leap out to seize it and drag it underwater.
During extreme environmental conditions such as droughts, heavy rains, or even freezing periods, crocodiles remain still to conserve energy, maintaining survival with minimal consumption until favorable hunting conditions return.
The extinction of dinosaurs resulted from arrogance, impulsiveness, and domination, while the survival of crocodiles is attributed to calmness, rationality, and patience.
