In fact, the earthquake fish is just another name for the yellow croaker, and the reason why people call the yellow croaker by this name is because the yellow croaker is a deep-sea fish, but whenever an earthquake occurs, especially in an ocean place, people will find that the yellow croaker will come to the shore. In fact, this phenomenon is quite common in living things, and the sensitivity to earthquakes can't be detected by people and machines. However, some animals are very sensitive to earthquakes, and the octopus is one of them. Therefore, because of its response to earthquakes, people also call it an earthquake fish.

In addition to the saying "earthquake fish", there is actually another saying about the yellow croaker. Many people have mistaken the octopus for the little white dragon in ancient Chinese legend, because it is different from the octopus we usually eat, and its volume is very large. As far as the discovered octopus is concerned, someone once witnessed a octopus with a length of seven meters and a weight of more than 270 kilograms. Moreover, because the waters where the yellow croaker lives are relatively deep, up to several hundred meters deep, people look like a silver little white dragon to the yellow croaker from a distance in the ocean. This is why people always think that the yellow croaker is like the dragon in ancient Chinese legend! In fact, the appearance of the octopus is very ugly, especially its head. The head of the octopus is not as handsome as its body, but very ugly, and the octopus is also very ferocious. Because of the deep waters, it is difficult to hunt, which leads to the fierceness of the octopus. However, in our daily life, it is difficult to find the trace of the yellow croaker on the surface of the ocean. At present, in several incidents of discovering the royal jelly fish, all the discovered royal jelly fish are dead. These royal jelly fish were discovered only after their bodies floated to the surface of the water and drifted to the shallow sea area.
