Strange creatures from the depths of the ocean

  Some people say that the appearance of creatures in the deep sea is related to the depth of the water. The deeper the distance from the sea, the uglier the appearance, because it is too dark to look at. Is this statement reliable? For deep-sea creatures, there are actually many secrets that you don’t know. The following editor will take you to reveal them.
  Great talent to get food
   the deep ocean basin is most seamounts environment, and this environment is relatively rare biological, so some people will be deep-called “ocean deserts”, although individual animals here is relatively small, but not the kind of less.
   Due to the limited sources of food available, most of the animals that can live in the deep sea are equipped with unique skills and have their own abilities when looking for food. For example, most deep-sea fish have a huge mouth, sharp and long teeth, and a pair of very large eyes. Once other fish or animals are bitten by them, they will be doomed. They will bite the prey. Until the prey is swallowed and digested. After a big meal, they can not eat for a long time, and then take the time to breed offspring.
   Some deep-sea fish usually bury their bodies in the sand, and grow a long handle above their mouth. At the end of the handle, there is a small luminous ball, which constantly swings as a bait to attract small fish or other small animals. Once it entered its attack range, it suddenly jumped up, opened its blood basin and swallowed the small fish in one bite. Because the deep sea creatures are barren, these fish have little chance of getting food, so they are called opportunists.
   Some deep-sea animals live by filtering food particles in the sea, such as sponges, corals, and sea anemones. Due to the lack of food particles in the deep sea, many filter-feeding deep-sea animals and the above-mentioned opportunistic predatory fish have low metabolic rates and very slow growth, so many deep-sea animals have very long life spans. The sponge, if any, grows to one or two meters long after tens of thousands of years.
   Wonderful form adapted to the marine environment
   In order to adapt to the particularity of the deep-sea environment, deep-sea animals have also derived many special forms. Of course, not all deep-sea creatures are ugly, but because they have a small chance of getting food, many deep-sea fish have large mouths and long teeth that they need to prey to ensure that they do not let the prey that reach their mouths escape. All are small or degraded. For example, the dominant species of latent shrimp in the biome of cold springs and hydrothermal vents, because its food source is the chemical energy microorganisms that grow on their bodies, latent shrimp no longer need to use vision to find food, so their eyes are also Gradually degenerate. There are also some sponges, which look like rocks.
   Color of the body can become weapons
   deep-sea floor in the true light of the following, there is no light, it can be said is a true dark world. Therefore, in order to better court and find companions, some deep-sea animals gradually make their body color appear as the bright red that spreads farthest in the sea and is most easily found by the same species. Such creatures often have developed vision and comparison. Its shallow sea relatives have larger eyes, such as long-spine stone crabs.
   Since food in the deep sea is scarce, and the pigments for body color require energy, many deep-sea animals choose white that does not require pigments to save energy. Sometimes, the living area of ​​the same deep-sea animals is small, and they don’t need to rely on sight to find companions and food. Therefore, the body color of some deep-sea animals is also pure white, such as white porcelain crab, sponge, coral, etc. Anemones and other species. For some deep-sea animals, most or all of their bodies are transparent in order to avoid natural enemies. Some deep-sea animals emit colorful biological lights at a certain stage of their life history, such as the reproduction stage.
   Special body structure
   was curious to shallow water or deep-sea animals will swell the sea after the explosion? In fact, the body structure of deep-sea animals is transparent inside and outside. For example, the worm-like sea cucumber has a sac-shaped body, but there are two channels between the mouth and the anus to make the skin inside and outside communicate. This way, although the pressure of deep sea water is very high, the pressure inside and outside the body of the sea cucumber is the same, so even in the shallow sea Or on the surface of the sea, the pressure inside and outside the body becomes smaller at the same time, and the internal and external pressure remains the same, so it will not burst.
   In crustacean shrimp and crabs, there are many soft tissues at the junction of the carapace and the body as channels to balance the water pressure inside and outside the body. Sponge animals, coelenterates, etc., have a large number of small holes in their bodies as passages, and they will not be damaged. As for the smallest tissue unit cell of an animal body, although it is a miniature sac-like body, its cell membrane also has countless small holes as material exchange channels, which can transmit water pressure to balance the pressure inside and outside the cell.
   Even the behemoth sperm whale in the ocean, in order to track its prey, can dive from the sea surface to more than 2,000 meters deep in a single breath within tens of minutes. It is an absolute diving champion. However, the external water pressure changes greatly but the sperm whale is unscathed. Although sperm whales, like humans, breathe with their lungs, sperm whales have adapted to the hunting life of the ocean and have a special mechanism to release air pressure in the lungs when they float up, so they will not damage the lungs due to changes in water pressure.
   Deep sea derived strange behavior
   due to the special nature of deep-sea environment, also derived from many deep-sea animals to adapt to the environment, unlike the special behavior of its shallow water close relatives. For example, deep-sea fish with long teeth and large mouths mostly rely on ambushing their prey or using bait to lure their prey. For another example, all types of sea cucumbers in shallow seas cannot swim, and can only crawl on the rocky or sandy bottom of the sea, but in the deep sea, there is a class of sea cucumbers that can swim, and the swimming style is quite graceful.
   For the mysterious deep-sea creatures, let me talk about it first. As for why they are so ugly, I believe you have the answer in your heart. The deep sea is mysterious, and deep-sea creatures have a lot of mysteries to be solved. With the in-depth development of deep-sea marine scientific research, more mysteries will surely be revealed in the future.
