5000 deep seabed creatures, amazing, how do they resist pressure

Hello! We are honored to answer for you: the physiology of deep-sea fish has changed a lot in order to adapt to the environment.

These changes are reflected in the muscles and bones of deep-sea fish. Due to the tremendous water pressure of the deep-sea environment, the bones of the fish become very thin; And it's easy to bend; The muscle tissue becomes particularly flexible and the fibrous tissue becomes surprisingly fine. What's even more interesting is that the skin tissue of the fish becomes just a very thin membrane, which fills the physiological tissues of the fish with water and maintains the balance of pressure inside and outside the body.

The internal and external pressures of deep-sea animals are the same, and the internal and external pressures of various tissues such as cell membranes can be transmitted within a certain range, just like a bottle, if the lid is not covered, no matter how deep the water is, it will not be deformed.

Of course, this pressure transmission has a certain range and speed, so most of the deep-sea animals die as soon as they come out of the water, and the opening from the inside is one of the reasons. Similarly, if it is suddenly sent into deeper water, it will also die.

Deep-sea animals have the same internal and external pressure, so they will not be fine, but they cannot survive in shallow water and low-pressure environments.

It's the same as if a person can survive in the air, but he will be squashed in reclaimed water.

The saury is a deep-sea creature, and if you look at its size, .........

Ask them to go, who knows!

Creatures below 100,000 meters in the deep sea are:

1. Long-snouted silver shark.

The body length is 60 200 cm, and the female is larger than the male. The body is stretched and the sides are flat. There are more than 20 species in 2 genera distributed in the Pacific and Atlantic coasts, and 4 species in 2 genera in China, distributed in the East China Sea and the South China Sea.

2. Vampire squid.

It is a luminescent creature covered in glowing organs that allow them to switch themselves on and off at will. When it turns off the light-emitting device, it is completely invisible in the dark environment it is in.

3. Giant deep-sea lice.

It belongs to the crustacean class of isopods and is the largest known member of the isopods, and its small isopod siblings, the tide worm, should be the most familiar one.

This large crustacean, while not a vegetarian, is not a ferocious animal either. They spend their lives cleaning up animal carcasses from the bottom of the sea.

4. Deep-sea Arowana.

It has a large head with a large number of long, pointed fangs. Similar to the Deep Sea CK, it also has a light emitter lure, except that it does not grow on the back of the head, but on the lower jaws.

5. Viper fish.

Usually found in water formations between 80 and 1,600 meters below the surface, the venomous snakefish is one of the most odious fish in this deep ocean. Some of these fish are black all over their bodies, and some parts of their bodies have luminous agitators, including long dorsal fins, which are used as bait.

The deep sea is the deep sea, which is located anywhere on the seabed between 2,000 and 5,000 meters below sea level, as opposed to the shallow sea. In the case of trenches, it can reach below 6,000 meters. In the deep sea, the sea is very cold, constant and low temperature (-1 4), there is no light, about 500 atmospheres (most of the deep-sea area is at 200-600 atmospheres).

Deep-sea biomes include deep-sea fish, invertebrates, and a small amount of phytoplankton. To date, the deep sea is not well understood.

The deep sea is formed by the cold water sinking of the oxygen-rich surface of the Arctic and Antarctic, and the number of organisms is small, and the oxygen consumption is low, so the oxygen content of the seawater increases, but when it reaches the bottom of the deep sea, the density of organisms inhabits is relatively high, and the oxygen content decreases. At the bottom of the deep sea, large areas are covered with fine sediments called soft mud.

Deep-sea biomes include deep-sea fish, invertebrates. Deep-sea fish mainly include hornfish, broadthroat, deep-sea eel and other fish. Invertebrates mainly include crustaceans, polychaetes, echinoderms, etc.

China's first self-designed, self-integrated and developed operational deep-sea manned submersible"Jiaolong"The diving depth reaches more than 7,000 meters, which can be used in the sea area, which is of great significance for the development and utilization of deep-sea resources in China.
