Eat, sleep and fight killer whales? Humpback whales are very proud: it is still very happy to see killer whales without food
Killer whales have no animals to be afraid of in the ocean, but they have the most hated animals, humpback whales. Humpback whales have a characteristic, that is, they are nosy, roaring when the sea sees injustice, and they will intervene when they see predators hunting them, especially killer whales. Humpback whales play diving Humpback whales are baleen whales, without sharp teeth, relying solely on their size and strength to entangle with killer whales. It stands to reason that the food eaten by killer whales cannot be eaten by humpback whales. The two of them have nothing to do with each other in the food chain. Why should they be enemies of each other? Let's walk into the love-hate relationship between humpback whales and killer whales. Flying up
its name is Kun
The scientific name of the humpback whale is the humpback whale, because its head looks like a musical instrument pipa, and the pipa is called "Zuo" in Japanese. The head", has the title of humpback whale. It is also called the big fin whale, named because of its huge pectoral fins. The Kun recorded in Chinese literature is likely to be the humpback whale. Humpback whales are distributed in various sea areas around the world, and there are traces of their activities in the Yellow Sea, East my country Sea, and South China Sea in China. As for why it is guessed that it is a humpback whale, it is mainly because it has a habit of rushing out of the water and then falling back down, splashing huge splashes of water. Coupled with its huge pectoral fins, it seems to be flying in the air. Beautiful posture Humpback whale is not a large whale in size, it is a medium whale, and even so, it can grow to about 15 meters and weigh about 25 to 30 tons. They are baleen whales and mainly eat a variety of small fish and shrimp, but also crustaceans. Humpback whales have the habit of migrating, and the migratory route is fixed, never taking a detour, always running for the shortest distance - a straight line. Scientists believe that humpback whales use Earth's magnetic field and the positions of the sun, moon and stars to help them identify their location. Compared with humans, humpback whales have a milder temperament, are close to people, and are friendly to other animals. They can often be observed swimming with dolphins. More importantly, humpback whales develop empathy, that is, when they see the weak being bullied, they will come forward to help. Adult humpback whales have few natural predators unless they are surrounded by a large group of killer whales. Humpback whales and dolphins swimming together The film crew of the BBC documentary "Story of Life" once filmed a pair of humpback whale mother and child surrounded by sharks, and a male humpback whale helped the mother and child escape. Zoologists in the wild have also found that humpback whales help gray whale mother and child escape from the mouth of killer whales, help dolphins stay away from killer whales, and even push divers out of the water because the killer whales come. Of the 10 cases where humpback whales helped, almost 8 were against killer whales. Killer whale said what the hell are you going to do? Humpback whale: I just like to see you can't eat. Why do humpback whales always get along with killer whales? Killer whales said: humpback whales, what are you doingHumpback whales with heroic loyalty
Humpback whales and killer whales on the bar, but also from the seat Speaking of head whales when they were young. As mentioned earlier, adult humpback whales basically have no natural enemies, but when they are young, they are very vulnerable. Killer whales and sharks are natural enemies of small humpback whales. Humpback whales live with their mothers until they reach adulthood. Females are a bit larger than males, and they use their pectoral fins and tail to lash intruders to protect their young. Such experiences can leave childhood shadows on juvenile humpback whales, who grow up resenting killer whales and sharks. If the mother humpback whale and its children encounter these two animals, they will interfere with them. For no reason, they will not let them hunt successfully in order to retaliate. Among the cases of humpback whale help, many are helping mothers with children, which shows that the experience of childhood has left a deep impression on humpback whales. Whales communicate with each other by means of sound waves, which travel much faster in water than in air and have a wider range. Humpback whales like to sing. They really sing, not roar. Their rhythm is similar to that of a symphony, and they can also emit 7 octaves. These sounds will be used for courtship during the breeding season, and will also convey information in peacetime. Therefore, the reputation of killer whales among humpback whales is inherently bad, and humpback whales get angry when they see it. Humpback whales are famous singers in the ocean. Humpback whales have a certain degree of sociality. They hunt in groups, use bubbles to surround the fish, and then catch them all in one net. The humpback whales that cooperate with each other do not even have any blood relationship, and some are just temporary partners. When they form a group, the humpback whales will communicate with each other through contact and friction. Generally speaking, social animals have richer emotions and stronger empathy ability. When they see killer whales bullying the weak, they will naturally not sit idly by. The swimming speed of humpback whales is relatively slow among whales, which also makes them easier to be parasitized by living creatures, among them the evil barnacles. Humpback whales cooperatively huntMarine Parasites
Barnacles are crustaceans widely distributed in the world's oceans, yes, barnacles and living shells, The conch has a long relationship, and it belongs to a big family with shrimp and crab. It belongs to a clade called cirripods, has poor swimming ability, and generally clings to rocks along the coast. However, it also attaches to slower-moving animals, such as turtles, humpback whales, gray whales, and more. The adhesion of barnacles mainly relies on the glue secreted by themselves, which is many times stronger than ordinary glue and can stick the barnacles to the surface of objects. And with the passage of time, the stickiness of this is getting stronger and stronger, and it is impossible to break it directly. There are too many parasitic barnacles in the flesh of the barnacles, which will increase the load and affect the swimming speed of the parasite. bump down. Barnacles, although annoying as parasites, can sometimes help humpback whales. If the parasitic position of the barnacles is on the pectoral fins and tails of humpback whales, this is tantamount to adding a hard meteor hammer, combined with the strength of humpback whales. No matter how powerful the killer whale is, it can't bear the slap of a humpback whale that is so much bigger than it. Barnacles are attached to the surface of objects. In addition to barnacles, there is also a little cutie called printhead fish. They have a "sole" on their head, which is actually a sucker. They use their suction cups to stick to everything they can touch, even more so than barnacles, because they can suck up the shark's skin. The scales of sharks are very special, with small spikes on them, and the glue of barnacles can't help, which is why whale sharks do not swim fast, but there are no barnacles parasitic. However, the sealhead fish are relatively unstoppable, and they can absorb anything, so they relied on this trick to swim across the ocean on a humpback whale. , This little day has been moisturizing. However, the sealhead fish is more aware of current affairs than the barnacles. It can detect the change in the humpback whale's behavior, so it quickly releases the sucker before the other party is about to jump out of the water, and slips away!

Although the number of humpback whales is not yet endangered, but because of its full ocean, zoology It is also difficult for families to say exactly how many humpback whales there are in the world. Every year, humpback whales are stranded or killed by ships. Because of the characteristics of their relatives, they will take the initiative to approach humans, causing them to be very close to the ships and be killed and injured by some high-speed ships. In addition, human whaling also has a huge impact on it. Japanese whaling does not dare to catch those rare, because it will cause huge public opinion and condemnation, so they kill the more common humpback whales. Japan's whaling vessels and the human pelagic fishing industry have dwindled some fish populations, humpback whales have been in short supply, and many juveniles have not survived to adulthood. This is not just the humpback whale, but even its deadly rival killer whale. At this point, the two mortal enemies who have fought for a lifetime turned out to be brothers and sisters. The humpback whale is the most studied baleen whale. First, because of its large number and large distribution area, it is found all over the world, and it is relatively easy to find it. Second, the swimming speed of humpback whales is very slow, and research ships can easily follow it for long-term observation. Human observation humpback whale zoologists have found a special kind of nerve cell in the brain of humpback whale, which exists only in the higher primates and dolphins. People have always thought that baleen whales are not as smart as toothed whales, but humpback whales said that baleen whales are not as clumsy as people think. From their heroic actions and vengeful killer whales, it can be seen that their thinking ability is not bad at all. Most of the baleen whales are small in number, secretive whereabouts, and little is known about them, so they can only be studied from humpback whales. What's more, humans have observed hybrid offspring of humpback whales and blue whales, humpback whales and fin whales in the wild. The DNA of whales in the ocean shows that fin whales and humpback whales are relatively closely related. Can you imagine that slender fin whales and short fat humpback whales are relatives?- Last：Administrative divisions of the United Arab Emirates
