Beast Studio

A killer whale family is mostly composed of adult females, immature males, and calves, with only a small number of adult males.

According to the living habits of mammals, after males reach sexual maturity, they will be kicked out of the family to avoid inbreeding.

Killer whales are a special case. Some males grow to 30 years old and still live with their mothers and sisters. However, they will not mate with their relatives. Their thinking is very similar to humans. They seem to know that doing so will affect the group. development of.

This is a thinking ability that other mammals cannot possess.

The adult male who remains in the family usually takes the responsibility of finding food. Sometimes the female parent will also participate in hunting, guiding the cubs step by step in learning hunting techniques.

However, when faced with powerful opponents such as large sharks and humpback whales, they do not dare to take risks. The male whales in the family will end the battle in the fastest and most direct way.

In Liu Wei's field of vision, five male killer whales killed the great white shark and dismembered its body. They did not eat immediately, but used a long humming sound to notify other members.

Soon, other killer whales from the family swam up.

Orca eating is a relatively slow process, and they do not fight and devour like crocodiles.

Instead, they swim over in a very orderly manner, with several male killer whales holding the prey in the water, and the other members take turns eating.

Females will first bite off pieces of meat to feed their young.

Viewers in the live broadcast room saw that the object it was feeding was at least nearly two meters long. Based on the body growth of the killer whale, it was estimated to be about four to five years old, but it still needed to be fed by its mother bite by bite.

"It's so big, I still need to feed it!"

"How doting!"

"My nephew is five years old and he still needs to be fed!"

“The living habits of killer whales are also similar to humans!”

Liu Wei was floating in the water, filming the big family eating from a distance, "Brothers, it will take a while for them to finish eating. Let me give you a brief introduction to killer whales first!"

When it comes to killer whales, the first thing that comes to mind is their intelligence. According to current research on known creatures on earth, scientists believe that killer whales are likely to be one of the species with intelligence closest to humans. They are similar to bottlenose dolphins, chimpanzees and As smart as an orangutan,

It's even possible that their intelligence exceeds theirs.

The intelligence of killer whales can be directly reflected in their hunting tactics. Today we saw the way they drive fish schools to lure prey. In their daily lives, there are more hunting tactics. For example, in polar regions, they tend to writhe together. It can create turbulent waves to lift seals off the ice, and can seize the seal's weak points and blow bubbles underwater to interfere with the seal's sight.

They also use sonar to vibrate the swim bladders of herrings to bring groups of herrings together, and then use their tails to swipe the schools of fish to feed on the stunned fish.

What’s even more incredible is that these creatures that live in the global sea have evolved an extremely complex language system that allows them to communicate with each other. For example, killer whales that have long lived near the poles can communicate with the long-term killer whales that live in various oceans. The killer whales can communicate without barriers, but according to genetic analysis, the killer whales living in each ocean are different, just like humans living in various countries around the world, communicating through a certain universal language. "

"Damn it, this is too exaggerated!"

"The killer whales living in the Chinese waters of the North Pacific said to the killer whales in the Atlantic: What are you looking at?"

"I cried with laughter! It turns out that killer whales can also speak in dialects!"

"Powerful language skills! Impressive!"

Liu Wei: “The powerful language system allows killer whales from various regions to migrate around the world in search of food and cooperation, which is similar to the early tribal culture of mankind.

There is another way of saying that the intelligence of killer whales is 2.5 times that of chimpanzees, which is equivalent to how many years old humans are.

This statement is relatively one-sided. The 2.5 times data is indeed a scientific measurement, but to be precise, this data is obtained by comparing the brain and body mass of killer whales and chimpanzees, and cannot be used as a comparison of the intelligence of the two.

The measurement of intelligence level is not a simple superposition of data. The intelligence of different organisms is expressed in different ways. Estimating the intelligence of a species requires a series of complex tests. For example, the most basic mirror test is used to judge the self-awareness of the species. In the popular science sea lion When I was studying, I mentioned this kind of intelligence test to you. In addition, there are also tests about sociality and logical thinking.

Through years of research and intelligence calculations by scientists on killer whales, it turns out that its intelligence is indeed very high. It is not just as simple as being good at hunting, but it also has strong language communication skills and stable and complex social relationships.

We all know that in nature, higher intelligence means stronger survival ability. This is also a main reason why killer whales have become the second mammal after humans to be able to spread all over the world. "

The audience in the live broadcast room was stunned for a while.

After listening to Liu Wei’s popular science, I have already regarded killer whales as “human beings” on the seabed!

The only difference is that in the process of evolution, there is a lack of a certain civilization, or a civilization unique to killer whales that humans have not yet studied.

The atmosphere in the live broadcast room was lively, and the barrage scrolled very fast. Liu Wei could feel the audience's curiosity about the killer whale, so he struck while the iron was hot and continued, "After talking about the intelligence of the killer whale, let's take a look at its combat effectiveness.

Because of their superior IQ, people often believe that the horrific performance of killer whales in the ocean comes from their intelligence. If they lose their intelligence, killer whales will have no choice but to be slaughtered by humans.

This view is also very one-sided. According to industry research and data analysis, apart from intelligence factors, killer whales are also a top ocean predator with extremely strong combat capabilities.

Let’s first take a look at the horrific record of killer whales in the ocean.

Baleen whales are the general name for 15 species of baleen whales in the ocean, including the familiar blue whales, gray whales, etc., which are giants of the deep sea.

Even though their size cannot be compared with them, killer whales still pose a great threat to 11 species of baleen whales, and they are also the only species capable of regularly preying on medium and large whales.

Killer whales are not bully and only capture the calves of large baleen whales. They also have records of killing humpback whales, sperm whales, and gray whales.

And it is very common for killer whales to kill adult gray whales and humpback whales alone.

From 1990 to 1993, 3,650 photos of humpback whales attacked by killer whales were observed in the waters of various countries in the North Pacific region, and obvious bite marks of killer whales can be found on them.

Similarly in other sea areas, the most attacked baleen whales are killer whales!

Take sperm whales as an example. We all know that adult male sperm whales are among the strongest in the ocean, but they can only protect themselves in front of a group of killer whales. Sometimes they cannot even save their wives and children, and watch their loved ones being killed. Killer whale pod hunting! "

"Is it so powerful?"

"Fat Tiger looks so cute, I didn't realize he was so strong!"

"King Kong Lolita!"
