The law of the jungle has always been the eternal law of nature, and the phenomenon of "praying mantis catching cicadas and yellow finches behind" is also a common thing. The National Oceanic and Atmospheric Administration (NOAA) recently released a video taken in the deep sea at the end of last month: a group of deep-sea sharks are eating the carcass of a swordfish, and they did not expect one of the sharks to be ambushed by a large fish to swallow on the spot.
It is reported that on June 28, when the NOAA marine team was exploring the seabed at about 1476 meters under the sea water outside South Carolina, the NOAA marine team accidentally photographed at least 11 deep-sea horn sharks nibbling on the carcass of a longsword fish of about 2.5 meters, and just when the researchers were shocked by the picture, a huge multi-saw perch rushed from behind, sheltered by the submarine, and then swallowed one of the horned sharks in one bite, leaving only a tail outside the mouth.
Wreckfish, also known as stone bass, is a large, ferocious carnivorous fish of the order Perciformes and the family Euthynaceae. This fish has a large head, a prominent lower palate, a body length of about 2 meters, and an average weight of more than 36 kilograms. It usually inhabits the bottom waters of the deep sea with shelter, migrates, and usually moves alone.
NOAA researchers pointed out that under normal circumstances, deep-sea sharks do not flock to each other, but if there is just a lot of food nearby, this special situation will appear, and the body of the swordfish has become an important element of this rare scene. Scientists call this situation "food fall", and when it appears, it is the key to the growth and survival of small fish. Oceanographer Peter Auster said: "This group of horn sharks may have swum a long way to eat the body of the swordfish that fell to the bottom of the sea. ”
In fact, this phenomenon is somewhat similar to "whale fall", but compared with "whale fall", it is a bit of a witch. Whale fall refers to the phenomenon in which the carcasses of cetaceans sink all the way from the surface of the ocean to the bottom of the sea after their death. The carcass of a single whale is said to provide a resource for the entire submarine ecosystem for up to a century. But I don't know if you know that sharks die in the ocean and will sink to the bottom of the sea, and there is also a romantic and lonely name. A whale dies, all things live, a shark dies, hundreds of millions of people laugh...
