Explaining the cause of the terrifying giant creatures under the sea

Experts have come up with solutions for why giant marine creatures reside in the deep ocean.

The cause of extermination of terrifying giant creatures under the sea

Scientists once said that what we know about the universe is more than what we know about the ocean. Because the seawater is quite dense, it is difficult for light to pass through, as we go deeper into the sea pressure increasing - making it difficult for explorers. So the expeditions to the deep sea are very few.

Even so, experts still try to take advantage of this to learn about it. One of the inspirations that helps the adventurer always find out is the giant creatures in the deep sea.

The question is why are deep creatures living in the deep sea? After many studies, in the end, the experts had their answers.

From giant creatures hidden under deep ocean .

A giant Oarfish fish up to 7m long was captured by the US Navy in areas near California. This animal named 'sea dragon' is believed by its appearance to be an omen for disasters and earthquakes.

Not only that, the Japanese spider crab species called Macrocheira kaempferi also surprised many scientists when weighing up to 20kg with a width of up to 12m, living at a depth of 6,000m below sea level.

This species of extinct finned finfish 65 million years ago was unexpectedly discovered by an oceanographer in 1938 off the coast of Africa. According to experts, this is certainly not the only individual of this species that still exists.

These creatures are just small examples to prove that there are countless giant sized animals that have existed in the deep sea . And with their research, scientists have partly turned on the secret that some species have such huge size.

. to the secret that some species have the size "terrible"

On January 23, 1960, for the first time oceanographer Jacques Piccard and US Navy lieutenant - Don Walsh dived 10,991 meters in the deepest oceanic trench of Mariana (in the Pacific Northwest) within 4 47 minutes with the spy submarine Trieste.

As a result, they discovered a whole new world. He said, 'The sea ​​floor is quite bright, clean and a wilderness with only algae and sand' . The following species are completely different when possessing a much larger size than the above-mentioned marine species .

From that day on, scientists paid more attention to the ocean floor . But the more they studied, the more they felt they were too vague about this place. What we know so far is only the coating on the mysteries here.

If you think that big seawater pressure will cause the species to be small and not big enough to adapt, then you are wrong. The reason is that sea pressure is not a problem of deep-sea organisms because their bodies are composed almost entirely of water. (The ratio of water in these organisms is higher than 70% of the body).

In addition, these organisms use the body's buoyancy to fight gravity so their size grows very strong.

To better understand scientists based on the laws of physics to explain the giant size phenomenon of these organisms. That is Kleiber's law and Bergmann's law.

Kleiber's law explains that the larger the amount of tissue in your body, the slower it will consume. Food in the ocean is very scarce, these species mainly rely on the amount of food flowing down from the upper layer. So they must evolve to increase body size to save energy.

For example, according to Kleiber's chart below, a dog weighing 10 kg needs to eat about 500 kcal / day and an elephant weighs 1,000 kg (100 times heavier) and needs only 10,000 kcal (only 20 times more).

Bergmann 's body size rule explains that populations of larger sized species are found in colder environments, and smaller species are found in warmer regions. However this is more a trend than a rule and there is still a lot of debate around it.

Is it that under the deep ocean - what is the most mysterious and dark place in the Earth? Scientists are now using all the most advanced techniques and technologies to learn about this ' new world' .
