has a very famous legend in Japan. According to legend, whenever the hairtail appears, there will be earthquakes or other natural disasters. Therefore, the locals call them earthquake fish, and in some places, they call them the messengers of the demons.
Recently, two earthquake fish were found near a fishing port in Japan. As a result, it caused panic among the local people, believing that there would be earthquakes or other natural disasters in the local area. So what's going on? Will natural disasters really happen?
Today, let’s talk about this topic.
Why can earthquake fish predict earthquake

It usually lives in warm waters of the Atlantic Ocean and the Pacific Ocean. It can live in depths of 20-1,000 meters, but most of it lives in sea water of 20-200 meters.
Earthquake fish are fierce in nature and feed on various small and medium-sized fish. Cephalopods and crabs are also their main food. Earthquake fish have large adult individuals, reaching 67-90 kilograms, and are larger fish. Because earthquake fish are large in size, they are usually rarely to shallow beaches, and the probability of being caught is very small, and scientists have studied them relatively little. However, according to records, when each local quake fish appears near shallow beaches, there will often be greater geological movements in the following days.
- In 2011, Taiwanese residents caught an earthquake fish weighing about 80 kilograms in shallow waters, but a magnitude 5.2 earthquake occurred within a few days.
- On June 15, 2012, an angler discovered an earthquake fish about 6 meters long while fishing by the sea, followed by a magnitude 4 earthquake in the local area.
- On May 31, 2013, Taiwanese residents found another earthquake fish on the beach. They rescued it and put it in the sea. However, not long after, it appeared on the beach again, and local residents had to take it home. Two days later, a magnitude 6.3 earthquake occurred in the local area...
The following figure shows the relationship between earthquake fish and earthquakes.
In the records of coastal residents, if earthquake fish appear, geological disasters will occur soon. This time, two earthquake fish were found near Japan, so local residents also began to feel uneasy.
So the question is, why are earthquake fish so closely related to earthquakes?
First of all, we must say that does not appear every time a fish appears in the earthquake, and there will be earthquakes in the local area. According to statistics, people have observed 24 earthquakes in the shallows, but only 10 were accompanied by earthquakes.
It can be seen from this that although earthquake fish can predict earthquakes, the connection is not so strong, and the accuracy rate is only about 50%. The reason why earthquake fish appear is accompanied by earthquakes is perhaps because their sensory systems are more sensitive than humans.
In addition to predicting earthquakes, earthquake fish are also called the king of herrings. This is because there are always earthquake fishes in places where herrings appear, and earthquake fish are still at the forefront of them, like the heads of the Hundred Ghosts’ Night Walk, so the locals call it the King of Herrings.
habits of earthquake fish
Due to the emergence of earthquake fish, it is often accompanied by earthquakes, so people regard this fish as unknown. In some places, it is even circulated: eating earthquake fish will bring bad luck. In Southeast Asian countries, there is also a legend that eating earthquake fish will lead to death.
Furthermore, earthquake fish rarely appear near the coastline, and they prefer to stay in the deep sea, so fishermen do not catch many. Therefore, in many countries, earthquake fish are not edible fish.
Although humans do not eat earthquake fish, the number of earthquake fish is still pitifully small, because earthquake fish reproduction is very slow.
During the breeding season, a large number of earthquake fish will come to breed near Savai Island in the South Pacific. Here, earthquake fish will chase and entangle each other, while female earthquake fish will surround the middle.
reproduction methods are different from other animals. earthquake fish mainly relies on in vitro fertilization. During the breeding period, female earthquake fish will lay about 100,000 eggs in the water. When it discharges the eggs, the gathering male earthquake fish will also discharge their own germ cells to fertilize the eggs.
Since the gathered male seismic fish will discharge germ cells at the same time, no one will know which fish egg is fertilized by which male seismic fish's germ cells, which ensures the genetic diversity of seismic fish.
However, since earthquake fish adopts an in vitro ovulation method, the offspring of earthquake fish do not have the protection of their father or mother, the hatching rate is not high, and a large number of small earthquake fish are eaten by other fish during their growth. There are not many seismic fish that can survive until adulthood, so their number has remained relatively small.
summary
Human beings are species that advocate the harmonious coexistence of man and nature, so we often associate some natural phenomena with organisms, such as: the rooster sings the world and the world.
Earthquake fish and earthquake are such a combination. However, from a scientific point of view, although the appearance of seismic fish is often accompanied by earthquakes, this does not mean that there is an inevitable connection between them.
