My Deep-sea Fishery

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

The body of a blue whale is very huge, a tongue can reach 2,000 kilograms, a skull can reach 3,000 kilograms, a liver can reach 1,000 kilograms, and even a heart can weigh 500 kilograms, which is 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 you straighten the intestines of an adult blue whale, it will be three hundred meters long.

Xiang Yang once saw a one-to-one model of blue whale blood vessels in the laboratory.

The blood vessels of the blue whale are thick enough to hold a child, and the dirty walls are more than sixty centimeters thick.

Such a huge heart and blood vessels provide the blue whale with immense power.

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

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

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 southern blue whales, it is possible to grow to this size. Otherwise, it would be difficult to grow to this size.

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

Including humpback whales, other species of whales appear short and stout.

The blue whale has a long vertebral body, which looks like an elongated and enlarged humpback whale.

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

Xiang Yang stared at the blue whale's back carefully. No matter how he looked at Xiang Yang, he felt that the blue whale did not have a dorsal fin.

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

But the other fins are very eye-catching.

This blue whale seems to be surfacing to breathe. It lifts its shoulders and stomata area out of the water, rising out of the water to a much greater extent than other large whales, and it spouts a spectacular vertical water column from time to time. The water column is as high as ten meters.

Standing on a boat a few hundred 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 five thousand liters, which is equivalent to five thousand bottles of mineral water per liter.

"Woo—"

After seeing Xiang Yang and their huge fleet, the huge blue whale let out a low sound, sounding a bit bleak and gentle whales, this sound seemed very sad at first.

At the same time, Xiang Yang also saw the tongue of the blue whale through the open mouth of the blue whale.

The tongue of this blue whale is very big, Xiang Yang estimated that 50 people can stand on its tongue.

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

"Brother Yang, can blue whales also survive in Antarctica?" Fang Youqun poke Xiang Yang's shoulder and asked in a puzzled manner.

Xiang Yang rolled his eyes reluctantly. He had already seen blue whales in the Antarctic, so why did he still ask such questions.

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

Outside of Antarctica, most of the blue whale habitat bays are flushed from land and river water into the ocean to bring extremely rich organic matter, which makes the water very fertile and promotes the proliferation of plankton.

The dense plankton attracts a large number of small fish and shrimps.

The blue whale’s stomach is divided into four. The first stomach is formed by the enlargement of the esophagus, so it has a huge appetite and 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 the blue whale is less than 2000 kg, it will feel hungry.

Krill is the most abundant animal in the world, widely distributed in the Arctic and Antarctic seas. It is precisely because of such a wealth of food and living in the water that there is no limit to support weight, so blue whales can grow so large.

The blue whales in Antarctica spend most of their time opening their mouths to swim in the dense plankton clusters. The two rows of plate-like whiskers on the mouth are like sieve, and there are many folds in the belly like the bellows of an accordion. It expands and shrinks, so that it can swallow the seawater and krill together, and then close its mouth, allowing the seawater to drain from the crevices, filtering out the shrimp and fish to swallow it.

In addition to rugged food, blue whales also have 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 Antarctica. This is closely related to the type and quantity of food.

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

The lungs of the 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 breaths of the blue whale, and only breathes once every fifteen minutes when it comes out of the water.

When the blue whale breathes, the exhaust gas such as carbon dioxide in the lungs is expelled from the nostril, and then fresh oxygen is inhaled. UU reading www.uukanshu. cm

Whenever the blue whale’s head is exposed to the surface of the water to breathe, expelling the carbon dioxide and other exhaust gas from the body, a strong hot air rushes out of the nostrils, the jet height can reach ten meters, and the nearby sea water will also be rolled up. Out to sea.

When the blue whale sprays water, it can make a magnificent water column appear on the blue sea. From a distance, it looks like a sea fountain, and at the same time it makes a loud sound like the air whistle of a train. It is the most authentic whale spray.

People generally determine the position of the blue whale based on the sound of the blue whale's jet, the height and shape of the whale's jet.

To Xiang Yang's regret, although blue whales live in all oceans, they are rarely seen in the waters of our country.

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. Very 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 consecutive times when breathing. Five jets.
