Why don't aquariums dare to raise great white sharks? With 32 captive records and none of them successfully surviving, are the living conditions of great white sharks different from those of other sharks?
Great white shark, also known as "man-eating shark", is one of the most ferocious large sharks in the deep sea shark, its tail fin is wide, swimming speed is extremely fast, fast and agile, amazing attack power, full of sharp serrations, it can be said that "a little friend" can definitely do it!
It is also one of the most difficult animals in the world to be captive, and throughout the ages, humans have tried to raise great white sharks in captivity 32 times, all of which ended in failure, and they lived an average of less than 24 days, the shortest death on the day of fishing, and the longest lived only 6 months.
Although for thousands of years, domesticated creatures such as cats, dogs, cows and horses have become loyal "partners" of human beings, those beasts that cannot be domesticated have also been locked up in zoos and aquariums for people to see, creating various commercial values.
But great white sharks, like the Great White Shark, are still fighting human slavery and captivity at the cost of their lives.
The country that has tried to keep great white sharks in captivity is the "evil" United States.
In the fifties of the twentieth century, it was the California Aquarium in the United States that began the first captive great white shark in human history, but the shark died on the first day it was just caught and put in the aquarium.
Since then, the crazy Americans have not given up, from the 70s to the 21st century have been constantly trying to keep captive great white sharks, but still unsuccessful, the longest living is a captive record of Monterey Bay Aquarium in the United States, the shark survived for 180 days in the museum, but the physical condition is really worrying, and finally can not escape the fate of premature death.
Under natural conditions, great white sharks live at least 70 years, but why can't they survive even half a year when they are farmed? Mainly caused by five reasons!
Cause 1: Death from trauma
In the 32 captive records of great white sharks, several sharks have died directly due to fatal trauma caused during fishing.
Because great white sharks have never been successfully kept in captivity, they must go to the deep sea every time they try captivity, and great white sharks have a very fierce personality, and if they are caught in a conventional way, they will inevitably be injured and disabled by struggle, tearing or attack.
In this case, these great white sharks are often dying after being caught, and then sent to such a strange and narrow environment as an aquarium, coupled with psychological and spiritual blows, they will naturally collapse and die quickly.
In addition, even if the shark is not severely damaged during fishing, the great white shark's demand for oxygen is high, and the lack of oxygen during transportation is also a difficult problem to solve.
Reason two: death from low temperature
Many animals on the earth are thermostatic animals and can maintain their body temperature stably, but the situation of the great white shark is more special, belonging to semi-thermostatic animals, that is, it must produce energy through sufficient body activity to maintain a relatively stable body temperature.
The average temperature of the sea water in the three oceans is generally about ten degrees Celsius, and the body temperature of a normal great white shark must be maintained at more than ten degrees Celsius above the sea temperature, about constant between 23 and 26 degrees, and to maintain this temperature, it must create energy by continuously moving the body, which is why the great white shark always swims in the deep sea.
But once it is kept in an aquarium, the situation is completely different.
First, due to objective factors, the water temperature in the aquarium pool cannot be consistent with the sea water, which will lead to confusion in the body temperature system of the great white shark.
Moreover, no matter how big your aquarium is, compared with the endless sea, it is a drop in the ocean, where great white sharks live here, their range of activities is severely limited, and they cannot maintain normal physical activity indicators, which causes insufficient energy production.
The problem of body temperature reduction, long time in a low temperature state, of course, it is difficult to maintain life!
Why don't aquariums dare to raise great white sharks? In addition to fishing injuries and deaths from low temperatures being the most common causes, three more causes are also crucial.
Reason 3: Death due to lack of oxygen
In fact, like the concept of maintaining body temperature, the great white shark is different from many other marine species, although it also breathes by gills, but his gills are particularly "chic", without gills, but are composed of several "gills" like cracks, which leads to its breathing in water is very special, must swim quickly in the water, passively hit the water into its gills, in order to obtain sufficient oxygen.
So another difficult problem under captivity conditions also arises, the aquarium pool is so big, when the great white shark needs enough oxygen and is preparing to quickly sprint to take oxygen, but who would have thought that before starting to accelerate, it was over.
Let's just say that such a small range can ensure that the shark needs enough oxygen? In a state of hypoxia for a long time, it does not die who dies!
Reason 4: Death by suicide
Don't think crookedly, the "suicide" mentioned here is not because the shark can't stand the active suicide, but because of a special organ in the great white shark's body, causing it to uncontrollably produce suicidal-like behavior.
There is a special inductive organ on the head of the great white shark, called "Lauren's ampulla", which is a great weapon for great white sharks when hunting, with a powerful navigation system, which can lock and kill prey by sensing ripples in the water.
But once in the small aquarium, the once hunting weapon is not only useless, but also a deadly burden, limited space makes the navigation system lose judgment, it is easy to misjudge the pool wall as prey, prompting sharks to rush towards it, which is why in most cases of captive great white sharks, sharks hit the pool wall, similar to suicide.
Reason 5: Single food
In the normal marine environment, the great white shark is at the top of the food chain, its diet is very rich, from small fish and shrimp, to sea lions and seals, it does not refuse, rich diet, but also promotes the multi-dimensional nutritional structure of wild great white sharks.
But once kept in captivity in the aquarium, what can be eaten is bound to become single, and the resulting nutritional deficiency will inevitably occur, which is one of the reasons for the common early death of captive great white sharks, and the great white shark that insisted on living for 180 days and eventually still died is the most typical case.
Today, 32 great white sharks have proved with their bloody lives that not all creatures on Earth can be kept captive by humans, and in the face of nature and life, when will we learn not to be driven by interests and desires and always remain in awe?!
