In marine life , there are many strange and strange species. Even if they are the same species, their juvenile and adult stages are different, , which is difficult to distinguish. Recently in the Great Barrier Reef waters of Australia, a diver discovered a strange fish. It has no ability to swim and can only float straight. It has an almost transparent body and a long hairstyle, which is very eye-catching. curious.
If this fish were not big enough and had a long beard, it would be easy to think that it looked like a sewing needle dropped in the ocean. It can also be distinguished from the head of this fish that this is an oarfish , which belongs to the juvenile stage of . Its body color is relatively white, while the body color of adult oarfish ranges from pink to basic red.
Oarfish generally live in the depth of 200-1000 meters in warm waters, and are generally rarely close to the Qianhai Sea. During the breeding season, oarfish will start to reproduce on the seabed covered with coral reefs. Female oarfish will last for 2 weeks during the breeding period. A total of about 100,000 fish eggs are laid from time to time, so this young oarfish may also come here with the movement of sea water.
- The peculiar swimming way of oarfish
The fins are important organs used by fish to swim and maintain body balance, helping fish swim quickly and balancedly. The way oarfish swims is to swing its long dorsal fin. swims vertically, and the fish body remains straight.
In ocean fish , blade fish also swims suspended in this way. The blade fish's fins are almost completely degraded , but there are still fins, but they are not obvious. Among them, the blade fish's dorsal fin has degenerated. The tail fin has also become smaller and smaller, so they have almost no ability to swim and can only levitate and float.
The oarfish swims vertically, head up and tail down, making it swim very slowly, almost floating in the ocean, but it is also a ferocious predator with hard upper and lower jaws. When it finds prey swimming above it, the oarfish will curl up its body and then pop it out quickly like a spring. This acceleration allows the oarfish to prey on other fish, squid, crabs and other prey. .
- The oarfish is known as the " earthquake fish ". Can it really predict marine earthquakes ?
The oarfish is the longest bony fish in the world. It is generally more than 3 meters long and can weigh up to 270 kilograms. Its ferocious face makes it a bit ferocious and scary. There are also sea snakes, Dragon Palace Messenger, Dragon Kingfish, big hairtail fish, big herring, etc. Among them, it is known as the "earthquake fish" because this deep-sea fish usually appears on the beach after ocean storms and is known as It is considered an ominous signal . Whenever oarfish appear in the shallows, there will be abnormal movements on the seafloor such as marine earthquakes or tsunamis.
Can oarfish really predict marine earthquakes? Generally speaking, deep-sea species such as oarfish rarely appear in shallow seas. Because of the different pressures, it is easy to cause casualties. Therefore, the appearance of deep-sea species in shoals is most likely related to deep-sea earthquakes. When the deep sea crust is abnormal , will cause these deep-sea species to have an abnormal sense of direction, causing them to run around in panic, hide in shallow seas, etc.
However, statistics show that oarfish appear in the shallows a lot of times , and there are relatively few abnormalities in the deep sea crust. Therefore, there are many reasons for the emergence of deep sea species. Whether it is related to earthquake precursors cannot be simply judged. , more scientific proof is needed.
It may be that deep-sea species suffer from some kind of disease, including injuries, which makes these deep-sea species unable to live in the deep sea as usual, unable to escape the waves, and finally washed into the shallows by the waves. Therefore, although the oarfish is called "earthquake" "fish", its appearance is not necessarily an abnormal movement of the seafloor, and cannot accurately predict earthquakes or tsunamis .
Pay attention to the six-dimensional nature, let nature take its course and understand nature !
