What's in the depths of the ocean? Today, we tell a few stories about the wonders of the deep sea.
In 2003, Australian scientists installed a sensor on a 3-meter-long great white shark in order to collect ocean data, and this ordinary experiment became strange just a few months later.
On this day, the data transmitted back by the sensor shows that the great white shark quickly dived from 230 meters to 680 meters, and the temperature also rose rapidly from 7 ° C to 23 ° C. The scientists in front of the display were confused.
After that, the searcher found the sensor near the beach according to the positioning, but there was only a lone sensor, the shark was missing, after inspection, the sensor was intact and functional, what happened to the sharp change in temperature and diving depth displayed by the sensor? Where did the sharks go again? There is only one possibility.
The 3-meter-long great white shark was swallowed by another creature and the temperature rose sharply to 23 degrees, which is the temperature of the organism's body, and then the behemoth took the shark down with it and returned to the 680m deep sea where it lived.
3m long shark was eaten in one bite, how big is the mouth of this creature, then how big will it be as a whole, the marine life currently known to mankind is not so big, there is, but it is an extinct prehistoric megalodon, is the prehistoric megalodon shark not extinct? Megalodon sharks became extinct as early as 3 million years ago.
Megalodon is an ancient creature living about 3.6 million years ago to 2300w years ago, at present many parts of the world throwing the tooth fossils of megalodon sharks, according to the size of the teeth, megalodon sharks may be up to 30m long, weigh more than 100t, bite force up to 30t, equivalent to the Tyrannosaurus rex ten times the number of the earth's highest, so the vigorous animal extinction so in the end is there extinction? Hear the next story.
In December 1938, South African fishermen caught a strange fish, which was covered with iron armor-like scales, short tail, and well-informed fishmen said that no one had ever seen this strange fish.
Back at the port, the museum's researchers heard the news and bought the strange fish and made a specimen 15m long.
Later, Professor Smith of the museum saw this fish and was also very curious, decided to dissect on the spot, the professor is the professor dissected without a word, with the deepening of the dissection, the professor's hand began to tremble, the expression also became stiff, what happened? Because the characteristics observed in the anatomy indicate that this is a coelacanth, coelacanth is a transitional species between fish and land animals.
He was once concluded by scientists that it had become extinct as early as 65 million years ago, so what was the situation with this coelacanth strip, and this thing was not extinct? Is he still alive? It is said that Professor Smith later fainted on the experimental table in excitement, and this is not the end.
1952 The second gun bureau is caught by fishermen again, and the coelacanth is thoroughly characterized as a living species on Earth.
Now that there are videos of coelacanths swimming freely in the ocean on the Internet, there is no doubt that no scientist has said that coelacanths are extinct, which is too hard to punch in the face.
Did the megalodon go extinct? Was the 3-meter-long great white shark swallowed by him? The total area of the ocean is 360 million square kilometers, which is 25 times the land area of human stepping on and doing all the land for him, which is really too big, the average depth of 3820m and the deepest depth of 11000m is higher than Mount Everest, in such a vast space, how many unknown creatures are filled, perhaps astronomically.
In the land, Africa, and amazon rainforests where humans can tread, new species are still found every day, not to mention such vast oceans. The Amazon rainforest is not even one-ten-thousandth of the ocean, and at present, human exploration of the ocean is only a pitiful 5%, so how can we easily conclude that they are extinct? The deep ocean may be the true face of the earth.
Okay, thanks for watching, and goodbye!
