On the question of which animal knows the fastest, we first need to understand the early warning mechanism and the perception of the animals. The early warning mainly relies on the P and S waves. P-waves, i.e., primary waves, propagate fast but less destructive; Whereas, the S wave, i.e., the secondary wave, has a slower propagation speed but more destructive power. Animals are far more sensitive to microshocks than humans, especially those in the ground or in the water.
Scientific cognition tells us that some animals, such as snakes, lizards, aquatic creatures, etc., can detect microseismic changes in the earth's crust in advance**. The early warning mechanism of these animals is mainly based on the hypersensitivity of their sensory organs, which are able to capture small vibrations and sound wave changes. When they perceive the primary wave of **, they can react quickly, and some can even react within a few seconds or tens of seconds.
In addition, the behavior patterns of animals are also the basis for judging whether they can perceive in advance. For example, some animals will show abnormal behavioral responses after perceiving **, such as sudden flight, gathering, chirping, etc. These patterns of behavior were observed and recorded over multiple occasions, providing us with evidence that the animal was able to perceive in advance.
Based on the above analysis, we can conclude that some animals do have more perceptual ability than humans in the pre-surface. These animals, through their highly sensitive sensory organs and specific behavioral patterns, are able to react quickly before they occur. Therefore, the answer is that some specific animals know the fastest**.
