My Deep-sea Fishery

Because the blue whale has a wide and flat tail and a streamlined body, it looks like a razor, so it is also called the razor whale.

The body of the blue whale is very huge, a tongue can reach 2,000 kilograms, a skull can reach 3,000 kilograms, a liver weighs 1,000 kilograms, and even a heart weighs 500 kilograms, much larger than an adult man.

In addition, it is said that the blood circulation of blue whales can reach more than 8,000 kilograms.

If the intestines of an adult blue whale were straightened, it would be three hundred meters long.

Xiang Yang had seen a 1:1 scale blue whale blood vessel model in the laboratory.

The blood vessels of the blue whale are thick enough to hold a child, and the visceral wall is more than 60 centimeters thick.

Such a huge heart and blood vessels provide the blue whale with incomparably huge strength.

The strength of the blue whale is astonishing, and the power it emits can reach more than 1,500 horsepower. It is a well-deserved giant and Hercules in the animal world.

The adult blue whale in front of me is estimated from its size, and its weight should be about 30 times that of an African elephant, which is considered huge among blue whales.

The average length of the average blue whale is only 25 meters, and the number of more than 30 meters is not too many.

Female whales are generally larger than male whales, and southern blue whales are generally larger than northern blue whales.

Because this blue whale is a female blue whale among the southern blue whales, it is possible to grow to such a large size, otherwise, it would be difficult to grow to this size.

Xiang Yang found that this blue whale was different from other types of whales that Xiang Yang had seen.

All other species of whales, including humpbacks, appear stocky.

The body of the blue whale is long vertebral, which looks like an elongated and enlarged humpback whale.

In addition, the dorsal fin of this blue whale is so small that the people on the boat can't see it at all. It is said that the dorsal fin of the blue whale is only briefly visible during the blue whale's dive.

Xiang Yang stared at the back of the blue whale carefully. No matter how he looked at it, Xiang Yang felt that the blue whale had no dorsal fin.

On the back of this blue whale, Xiang Yang only saw a bump that was just visible.

However, the other fins are very conspicuous.

The blue whale appears to be surfacing to breathe, lifting its shoulders and blowhole area out of the water much more than other large cetaceans, and spewing out a spectacular vertical column of water from time to time, The water column is as high as ten meters.

Standing on the boat hundreds of meters away, Xiang Yang could easily feel the terrifying power of the water column.

It is said that the lung capacity of a blue whale can reach a terrifying 5,000 liters, which is equivalent to 5,000 bottles of mineral water per liter.

"Woo--"

After seeing Xiang Yang and his huge fleet, the huge blue whale uttered a deep, desolate and melodious whale cry, which seemed very sad at first glance.

At the same time, Xiang Yang saw the blue whale's tongue through the blue whale's open mouth.

The tongue of this blue whale is so big that Xiang Yang estimates that 50 people can stand on it.

Involuntarily, Xiang Yang remembered a passage he had read in a textbook before. The heart of a blue whale is as big as a car. Babies can crawl through the arteries of a blue whale. A newborn blue whale cub is bigger than an adult elephant. Heavy.

"Brother Yang, can blue whales survive in Antarctica?" Fang Youqun poked Xiang Yang's shoulder and asked in confusion.

Xiang Yang rolled his eyes helplessly. He had already seen blue whales in Antarctica, so why would he ask such a question.

However, Xiang Yang answered patiently: "The intersection of warm sea water and cold sea water is an excellent habitat for blue whales. The cold sea water is usually rich in plankton and krill, and blue whales usually feed on these two creatures. , blue whales are distributed worldwide, and the number of blue whales distributed in Antarctic waters is the largest."

Most of the bays where blue whales live outside Antarctica are extremely rich in organic matter washed into the ocean by land river water, which makes the water very fertile and promotes the massive reproduction of plankton.

And the dense plankton attracts a large number of small fish and shrimp.

The stomach of the blue whale is divided into four. The first stomach is formed by the expansion of the esophagus, so it has a huge appetite. It can swallow 2 million krill at a time.

An adult blue whale eats 4000-8000 kilograms of food every day.

If the food in the belly of a blue whale is less than 2000 kilograms, it will feel hungry.

Krill is the animal with the largest number in the world, and it is widely distributed in the Arctic and Antarctic sea areas. It is precisely because of such abundant food and the fact that there is no weight limit for living in the water that blue whales can grow so huge.

Blue whales in Antarctica spend most of their time cruising in dense plankton with their mouths wide open. The two rows of plate-shaped whiskers on the mouth are like sieves, and there are many folds like accordion bellows in their stomachs. It can expand and shrink, so that it can swallow the seawater and krill together, and then close its mouth to let the seawater discharge from the crevices, and filter down the shrimp and fish to eat.

In addition to bony food, blue whales eat other shrimps, small fish, jellyfish, diatoms, and various plankton. In contrast, blue whales living in the northern waters are smaller than those living in the waters near the Antarctic. This is closely related to the type and quantity of its food.

Although blue whales live in the sea, they breathe with their lungs just like other mammals.

The lungs of a blue whale weigh more than 1,000 kilograms and can hold more than 1,000 liters of air.

Such a large lung capacity greatly reduces the number of times the blue whale breathes, and only comes out of the water to breathe once every fifteen minutes.

When the blue whale breathes, it first expels the carbon dioxide and other waste gases in the lungs from the nostrils, and then inhales fresh oxygen.

Whenever the head of the blue whale breathes out of the water and expels the carbon dioxide and other exhaust gases in the body, a powerful scorching air will rush out of the nostrils, and the height of the jet can reach ten meters, and the nearby seawater will also be rolled up. out to sea.

When the blue whale spouts water, it can make a spectacular water column appear on the blue sea. From a distance, it looks like a fountain on the sea. At the same time, it makes a loud sound like the whistle of a train. This is the most authentic whale spout.

People generally determine the location of the blue whale based on the sound it makes when it blows, the height and shape of the blowout.

What regrets Xiang Yang is that although blue whales live in all oceans, they are rarely seen in my country's waters.

There have been records of blue whales in my country's Yellow Sea and South China Sea, but no one has found them in my country's waters in recent years.

The blue whale is not a diving expert. It generally does not dive more than 100 meters at a time. Few individuals can dive to a depth of 500 meters. The diving time can last for about 20 minutes, and it will last for eight to ten when breathing. Five puffs.
