The deep-sea fish, sangalchi, was caught by anglers at a breakwater along the coast of Korea.
There are concerns that it may be a precursor to an earthquake.
On the afternoon of the 8th, at the breakwater of Geumjin Port, Gangneung, Gangwon-do, angler Yoon Mo caught a 3-meter-long sangalchi.
Sangalchi is a deep-sea fish that lives in the Pacific and Indian oceans, including Korea and Japan, and has a similar appearance to cutlassfish.
Some people expressed anxiety, saying that the discovery of deep-sea fish such as sangalchi off the coast is a harbinger of an earthquake.
However, experts say there is no connection with the earthquake, and explain that it is highly likely that the deep-sea fish came to the surface to find food and then were swept away by strong waves.
In fact, in 2019, according to a research paper published in the American Journal by a joint research team of Tokai University and Shizuoka Prefectural University, Japan investigated the relevance of earthquakes within a month after sightings of deep-sea fish such as sangalchi in the waters of Japan for 20 years from 1992 to 2011. As a result, only 8% of cases were matched.
