Killer whales own statements, how do killer whales communicate?

Hello everyone, I'm tall, long, and ......of adult blue whales. Just now, I was swimming in the ocean. You must want to know more about me, so I'll tell you a little bit about my physical features

We are heavier than elephants, bigger than elephants. The largest weighs about 160,000 kilograms, and the calves weigh 2,000 kilograms. Once, humans discovered my 40,000-kilogram 17-meter-long blue whale, and my tongue was as heavy as a dozen big fat pigs, and my mouth was still very wide.

In ancient times, my ancestors lived on land like the ancestors of cattle and sheep, and then evolved to live in the sea. Their evolution is very long, the forelimbs and tail gradually become fins, and the hind limbs completely degenerate into the appearance of fish, and then live in the ocean.

There are many species of whales, such as killer whales, baleen whales, ......Of course, it also includes blue whales, but they are generally divided into two main categories, killer whales and baleen whales. Baleen cetaceans have no teeth, while killer whales have hard, sharp teeth, and I belong to the category of toothless baleen cetaceans.

My habits are also worth paying attention to. I breathe with my lungs like cattle and sheep, which means that I am not a fish, but a mammal. When I breathe, a column of water is sprayed on the surface of the sea, like a fountain in a park, and I can judge the type and size of the droplets by their size and thickness.

We also want to sleep, and when we sleep, we will find a safer place, and we will sleep together, with our heads facing inwards and our tails facing outwards, and if there is any movement, we will immediately spread out in all directions, so that the enemy will not know which one to chase. I was born viviparously and grew up on my mother's milk, which also proves that I am a mammal. I was born more than ten meters long, weighed 7,000 kilograms, and could grow 30 to 50 kilograms a day.

They generally live for 80 to 100 years.

Our fertility was poor, and it took two years to give birth to a calf. Due to human hunting and environmental pollution, we have less than 50 blue whales, our whales have lived in the world for more than 50 million years, more than 360,000 have been killed, and now many whales are extinct.

Someone's coming to hunt me down, so I'll go first. Help me! Someone's going to kill me! ”

The cost of the killer whale's self-report is sudden.

1. Each killer whale group has its own communication system.

Killer whales have a complex communication system that includes a wide variety of voices, including singing and whistling. Since the members of the same group spend a lot of time together, they begin to build their own voices** to identify them, and this is something that the other members can't understand.

2. Killer whales will go through menopause.

There aren't many menopausal mammals, but killer whales are one of them. Females lose their ability to reproduce at a certain age but live longer.

3. The lifespan in the natural habitat is longer than that in captivity.

Although scientists don't agree on how long the Great Oak Killer Whale can live in its natural habitat, in captivity, killer whales live no more than 20 years.

4. There is a unique mark on the dorsal fin.

This area works in a similar way to our fingerprints. Therefore, each killer whale can be clearly distinguished by this, which is useful for scientists to identify them.

There is a copy of the text, the 5th grade text "Whale", who doesn't know.

It's wonderful to be so ** killer whales.

He is actually the "master of language" in the cetacean kingdom. Studies have shown that killer whales can make 62 different sounds, and each sound has different meanings. Killer whales living in different sea areas, and even different groups of killer whales, use different degrees of language pitch, similar to human dialects, so researchers call it "killer whale dialect".

Sometimes, a large number of fish appear in a certain area, and schools of killer whales come from all over the world to feed. But their cries are different from each other. Researchers speculate that killer whales can converse with each other through "language", and whether they understand each other's "dialects" and whether they are also equipped with an interpreter like humans remains a mystery.

Sympathy, especially since the Japanese have a habit of whaling.

Our blue whale is the largest of all animals known to have survived ancient times. It is about 30 meters long and weighs between 150 and 200 tons, which is equivalent to the weight of more than 25 Asian elephants or more than 300 people combined. The body of our blue whale is pale blue or mouse gray, and there are pale fine patterns on the back, and there are white spots on the chest, which is beautiful.

Our big tail is wide and flat, and the whole body is streamlined, which looks like a razor, so we are also called "razorwhales".

Although we live in the sea, we breathe with our lungs just like other mammals. Our lungs weigh more than 1,000 kilograms and can hold more than 1,000 liters of air. Because of such a large lung volume, we can breathe so much less, about every 10 to 15 minutes that we breathe out of the water.

When breathing, exhaust gases such as carbon dioxide from the lungs are expelled from the nostrils before fresh air is inhaled.

Because my body is so big, I have to eat a lot of Dongmu every day, and my favorite food is scale shrimp. We can devour more than 2 million shrimp at a time, and we can eat 4,000 to 8,000 kilograms a day! If we have less than 2000 kilograms of things in our stomach, we will feel hungry.

Since the scale shrimp is widely distributed in the north and south poles, we have lived in the polar regions for generations, rarely in tropical waters, in order to get enough food.

We are full of treasures, which have high economic value. Our body is rich in oil, and our beard, skin, bones, flesh and internal organs can be used as raw materials for industry, light industry, and food processing industry. Because of this, humans have hunted and killed us in large numbers, bringing our family to the brink of extinction and the lives of many of our companions.

Here, I hope that our human friends can live in harmony with us and make our earth home full of vitality and vitality.
