Black whales, also known as "killer whales", are widely distributed in the world's oceans, including the Yellow Sea, Bohai Sea and South China Sea.
Ask you who is the overlord in the sea? You may not hesitate to answer: shark. Wrong. The real overlord in the sea is the killer whale, and the shark is just a side dish in front of the killer whale.
Black whale is a smaller cetacean. Its maximum length is only 10 meter and its weight is 7-8 tons. It is bold, cunning, cruel, greedy and omnivorous. With its speed of 55 kilometers per hour, it can double its swimming speed when chasing prey. No matter what animals are found in the ocean, they can't escape from the tiger's mouth, from fish, shrimp, seabirds to shark walrus. It has also been found that a killer whale can swallow 60 young whales at a time. It is speculated that the daily intake of killer whales should account for at least 4% of their body weight, that is to say, an 8-ton killer whale eats 0.32 tons of food every day, which shows that it is very harmful to marine animals.
Black whales are bold and have a wide range of activities. Other cetaceans generally do not communicate with each other between the northern and southern hemispheres, and between the Pacific Ocean and the Atlantic Ocean. Only killer whales are not restricted by national boundaries. They can swim freely from the Antarctic Sea to the Arctic Ocean, from the eastern hemisphere to the western hemisphere, and "swim here" wherever they can swim.
Black whales are fierce, cruel and cunning. When they meet a whale, they will "organize", surround it first, and then two killer whales will rush up and bite its two flippers, making it difficult for them to escape. Then other killer whales will bite them violently. After eating for a while, there will be killer whales instead of whales that bite fins. Let them also enjoy delicious food. Minke whales, humpback whales, gray whales and even the biggest blue whales are often attacked by them and become things in their stomachs. Sometimes they find that the whale hunting boat is dragging the dead whale, regardless of the bombardment of the whale cannon, it rushes into the shell of the whale, eats the whale oil inside and flies away.
When killer whales meet a group of fish, they don't immediately jump on them and bite. Instead, a group of killer whales scattered around the fish, swimming around the periphery, driving the fish into the encirclement, and then everyone rushed into the circle in turn for a good meal. If you meet a seal or penguin standing on an ice floe, the killer whale will jump to the edge of the ice floe and press the ice floe to its own inclined direction, so that the animals on the ice will stand unsteadily and jump on their mouths as soon as they slip.
The most spectacular scene is the scuffle between killer whales and walruses. Walruses will gather together quickly when they meet killer whales, and baby walruses will live in the middle of the sea and prepare to fight with killer whales. The killer whales first lined up in front of the walrus with 5-6 whales to attract the walrus' attention, and then other killer whales sneaked around behind the walrus and launched a sudden attack. When the walruses were in chaos, killer whales swarmed ahead, biting and killing walruses everywhere, and the waves were spattered with blood.
Although the killer whale is fierce and cruel, it is a friend of mankind. So far, there is no record of killer whales attacking humans in the world. On the contrary, because of its wisdom, some people train killer whales to serve mankind. For example, people in coastal tourist areas train killer whales for tourists' entertainment When killer whales hear the call signal, they will immediately swim to the shore to let tourists ride on their backs and swim in the water, and then they can send people back to the shore according to the instructions.
Fishermen at the Australian whaling base train killer whales to help catch other large whales. Usually, they let the trained killer whales act as detectives on the high seas. Once a whale is found, several killer whales will guard it to prevent it from escaping. In addition, some killer whales will report to the port. After returning to the harbor, they will jump around the base and roll around to attract people's attention. Whaling ships will lead the way when they set sail. After the ship shelled the big whale, they would alternately jump on the jet holes that oppressed the injured whale to stop breathing, and they would also dive below the injured whale to prevent it from diving and escaping. When the whaling ship subdues the injured whale, the fishermen only need to give them the killer whale's favorite whale tongue, and they will be satisfied.
Because killer whales are fierce and violent, other marine animals are frightened by the news. Therefore, some fishermen recorded the cries of killer whales and played them by the farms to drive out the natural enemies of aquaculture and protect aquaculture from harm.
The black whale is a veritable marine tiger. Its Dutch and English names mean "whale killer", which shows its ferocity and ferocity. Black whales are also called "killer whales" because the tall dorsal fin of male killer whales is like the shape of an ancient weapon-a halberd hanging upside down on the sea.
Someone found a dozen dolphins and the same number of seals in the stomach of a killer whale, which proved the cruelty, cruelty and gluttony of killer whales. In fact, the blue whale, the king of animals, can't escape the fate of being hunted even if it comes across a group of killer whales. When besieging the blue whale, the killer whale has a very precise division of labor: some killer whales are on its sides, two killer whales are in front of it, and the other two are behind it to prevent the blue whale from escaping; Other killer whales forced the blue whale to sink underwater and prevented it from breathing out of the water; There are also some killer whales watching under its belly to prevent it from diving away. The blue whale was bitten off its dorsal fin first, and its caudal leaf was torn to pieces, making it impossible to swim. At this time, the killer whales scrambled to bite the meat of the blue whale in chunks and had a delicious meal.
Killer whales become the overlord of the sea because they have the corresponding conditions: first, their teeth are sharp, their teeth bend inward and backward, and their upper and lower teeth are staggered, which not only makes it difficult for their prey to escape, but also tears and cuts their prey; Second, it has the ability to hunt prey quickly and accurately. The killer whale's tall dorsal fin can act as a "rudder" to ensure the balance of the body when hunting; Third, it is insatiable and preys on carnivorous life. Almost all other animals in the ocean can be its food, and it is very cunning, and there are fashions to trap prey; Fourth, killer whales are gregarious animals, often moving in small groups of 3-4, often reaching 30-40, and the power of collective hunting is of course greatly increased.
In addition, killer whales also have a strange hobby, that is, they like to eat whales' lips and tongues. Someone observed 35 captured gray whales and found that 7 of them had been partially or completely eaten by killer whales. Obviously, these gray whales were attacked by killer whales. Sometimes, when a whale is killed by a whaling gun, floats on the sea or is towed by a boat, the killer whale will fish in troubled waters, drill into the mouth of the dead whale, and put his lips and tongue into the mouth of the dead whale.
Such a fierce killer whale is actually a "master of language" in the whale kingdom, which is amazing. Research shows that killer whales can make 62 different sounds, and different sounds have different meanings. Black whales living in different sea areas, even different killer whales, use different language tones, which are similar to human dialects, so researchers call them "killer whale dialects". Sometimes, a large number of fish will appear in a certain sea area. Black whales flock from all directions for food. But their calls are different from each other. Researchers speculate that killer whales can talk through "language". As for how they understand each other's "dialects", whether they are equipped with translators like humans is still a mystery.
It is worth mentioning that although killer whales are fierce, they have never witnessed or heard of cases in which killer whales hurt humans, and the domesticated killer whales are gentle and even perform many wonderful programs.
Black whales are fierce, bold, cunning, cruel and greedy. They are typical "thugs" in the sea. They can attack sea lions, dolphins, seals and walruses, even large baleen whales (such as blue whales), and they dare to attack them. Of course, squid, penguins, fish, seabirds and other marine animals are also their prey. Black whales make terrible noises when chasing animals.
The sailors witnessed several killer whales jointly attacking a baleen whale. Among them, three male killer whales attacked the baleen whales, while the other two female killer whales and several trailing whales watched the battle, and the whales were killed in less than an hour. Several other killer whales on the sidelines swarmed, tearing up the whales and eating them separately. Attacking large whales is often a collective action of dozens of killer whales, biting their heads, tails and other parts respectively, and whipping them with their tail fins. Sometimes in droves. Black whales suddenly rushed in, and sea lions and seals were scared to run for their lives. Black whales rushed into their sheep, and immediately the sea was red with blood, and their bodies were all over the sea. Even if sea lions and seals bask in the sun on ice or rocks, killer whales can go ashore to catch them and then hunt them. Black whales are also very cunning, sometimes lying on their bellies and floating on the sea like corpses. When seabirds or marine animals approach, killer whales will suddenly turn over and catch them. Black calf whale
Black whale, with smooth skin and black back, has a thick layer of fat under the skin to prevent the body from emitting heat to adapt to life in cold seawater. The abdomen is white, the back is black and white, and the streamlined figure is quite beautiful. Noses grow on the top of the head, which is very suitable for regular breathing and ventilation. The nostril has a flap that can be opened and closed freely, so it will not be invaded by seawater. When the killer whale breathes in the water, it raises its head.
The male killer whale is about10m long,1.8m high and weighs 7-8 tons. The dorsal fin protrudes out of the water like an ancient weapon "Ji", so it is also called "killer whale". Female killer whales are slightly smaller, about 8 meters long and weigh 5-6 tons. Killer whales swim very fast and can swim 30 miles an hour.
The breeding of killer whales is not monogamous. A young male killer whale and several female killer whales form a reproductive group, and the size of this reproductive group depends on the ability of male and same-sex fighting couples. There are more females in the strong and fewer females in the weak, ranging from 30-40 to 3-5. Black whales have no fixed breeding season and can mate all year round. The pregnant female killer whale is about pregnant. Twins are rare. The newborn killer whale is about 24 meters long and can eat independently after living with its mother for one year. When they grow to more than 6 meters long, their father drives the male killer whales out of the reproductive group and lets them live a single life. When they are strong, they will fight other killer whale men and rob their spouses to form another reproductive group.
Black whales are fierce, but sometimes they cooperate with others. There is a whaling base off the coast of New South Wales, Australia. Every year, when humpback whales migrate through this area, some killer whales will quickly swim near the base and get there to attract people's attention. When the whaling ships at the base set sail, they automatically acted as guides to guide the whaling ships to whales. At this time, other killer whales in the sea blocked humpback whales and prevented them from escaping. When the black whale helped the people on board subdue it, two killer whales swam under the humpback part of the injured whale to prevent the humpback whale from diving into the water, and the other two killer whales jumped into the jet port of the injured whale to prevent it from breathing and breathing. When people catch humpback whales, they are allowed to eat their tongues as a reward.
As early as World War I, Russian and British troops tried to test seals and sea lions to detect enemy submarines, but the success rate was not great. Today, the U.S. Navy's underwater combat center in Hawaii spends millions of dollars every year to train a marine animal-killer whale. "Aben" is one of them. Now it has been trained to detect enemy submarines and has "skills" such as navigation and mine clearance. The United States has successfully trained killer whales to salvage seabed relics. Some scientists imagine that killer whales will be trained as "police dogs" in undersea pastures to manage artificial fish and shrimp farms and scare away other marine animals that endanger fish and shrimp. Near Catalina Island in the United States, a large number of squid groups come here to lay eggs at one time every year, which is a good opportunity for fishermen to catch squid. At this time, sea lions, giant whales, seals and other marine animals also followed them to hunt. It has greatly affected fishermen to catch squid. Fishermen recorded the cries of killer whales and played them on the sea, but the marine animals fled after hearing the sounds and were afraid to go near them. There is a river rich in giant salamander in Alaska, and beluga whales go upstream with the rising river. At most, hundreds of beluga whales compete with fishermen for salmon. The fishermen used bombs, but it didn't help to drive them away. However, after the recording of killer whales was played, the beluga whales fled. This not only protects the fishing industry, but also avoids killing white whales.
Black whales can be found in all sea areas on the earth, but the killer whales in Japan's offshore, Antarctic and Norwegian to Arctic waters have the largest number; There are also many killer whales along the coast of China.
