The oceans account for 71% of the earth's area, the oceans are so vast that human beings are so small compared to the oceans that not even an ant is counted, and each of us is born with an unknown fear of the deep sea.
Have you ever wondered what exactly is 10,000m under the sea?
。 The Mariana Trench is currently the deepest known ocean. In 1957, a Soviet research vessel measured the depth of the Mariana Trench at 11,034 m
Putting the world's tallest Himalayas inside is still more than two thousand meters away from being exposed.
In 1960 the U.S. Navy's deep submersibles dived into the Mariana Trench 10916m.
In March 2012, Hollywood director Cameron, aboard the Deep Sea Challenger, dived to the Mariana Trench. Cameron explored the ocean floor for more than three hours.
Is the bottom of the trench eternal dark temperature only a few degrees Celsius? The water pressure was equivalent to 1,000 atmospheres which was the expedition he also collected biological and geological samples
So what exactly is on the ocean floor?
Too shallow, let's not talk about starting with 1km under the sea, because from this depth, you really enter the dark deep sea layer, and the sunlight can only penetrate a depth of about 1000 meters at most. There is no sunlight here and it is a completely dark world
Due to the long-term living in the dark environment, the creatures here have basically degraded their eyes, and some creatures have evolved light-emitting devices.
It's home to one of the most fascinating and exotic marine creatures, the deep-sea anglerfish.
He has an organ like a fishing rod on his body, which can emit light and is used to lure food.
An ugly deep-sea shark has been found at 1300m underwater, which is European-style sharp-billed sand. Because it is so rare, scientists know very little about them,
1300m, there is also a very terrifying shark here, the man-eating shark, which belongs to the large and ferocious shark and is widely distributed in the coastal waters of the world's oceans.
1500m under the sea, here lives a primitive shark Zou gill shark, his body on both sides of the six cracks covered and cover each other, so it is named Zou gill shark. With a body length of about 1.5 m, his reproductive rate is very low and the number is very rare
。 It has been listed on the IUCN Red List of Threatened Species.
Perched at depths of 1500 you also have a deep-sea dragonfish which is a ferocious predator whose head is particularly large and has a large number of long, pointed fangs.
His jaw grew a luminous bait, and he kept flashing to lure his prey by swinging back and forth. There are also two rows of light emitters on either side of the deep-sea Arowana.
Two kilometres of sperm whales live here. Sperm whale body length can reach 20m weight 50 tons Head accounted for 1/3 of the body diving ability is extremely strong is the deepest diving, the longest diving time mammal
The water is 3700 meters, which is the average depth of the ocean. It is also the location of the shipwreck of the famous Titanic. The hull has been broken into two pieces, and the distance between them is 600 meters, and for various reasons, it has not been salvaged.
Underwater 5,000 metres, where the temperature is close to freezing and food is extremely scarce, there lives a terrifying creature, the fangfish.
。 The fangfish gets its name from its large teeth and looks threatening. This fish can grow to about 15 cm
。 Their teeth are probably the largest of the marine fish relative to their body size, so some fish larger than them have become their food.
。 Below 6km under the sea, here is called the Abyss Zone, the species here. The number and diversity are very low 8km Mariana lionfish under the seafloor
In 2014 and 2017, researchers discovered a new species of lion and fish fish at a depth of more than 8,000 meters, which is also the deepest known diving depth
10,000m under the sea here you can no longer see any fish. Only a small number of microbes can survive here
。 The seabed is 11034m. It is the deepest part of the Mariana Trench and the deepest part of the ocean known to man.
