Darwin. The theory of evolution points out that natural selection, the survival of the fittest, and the elimination of the unsuitable. For the same species, only organisms that adapt to the environment can survive, and those who do not adapt will be eliminated.
Over billions of years, organisms have evolved to adapt to their environment. It can also be said that different environments create various characteristics of living things, which makes the earth full of all kinds of strange creatures.
Sperm whale. The nostrils have changed their functional structure over a long period of evolution. When it comes to sperm whales, everyone's first impression is that of a behemoth in the deep sea, its head is so large that it can occupy 1 3 of its entire body.
It is also the deepest and longest dive animal in the world. The sperm whale's gastrointestinal secretion, "dragon incense", is also an expensive material. Although the incense is smelly at first, after physical and chemical changes such as natural fermentation and air drying, it will become a very fragrant thing, which can not only be used as a spice, but also as an expensive Chinese medicinal material.
The nostrils of the sperm whale have evolved to create new structures. First of all, unlike other creatures, the left nostril of the sperm whale is not in the middle of the forehead, but in the left front of the head. At the same time, sperm whales can only inhale and exhale through their left nostril.
Its left nostril consists of the sphincter.
composition, because when diving it is necessary to close the nostrils tightly and also to resist strong water pressure, its nostrils must be controlled by strong muscles. Our common sperm whale emerges from the fountain, and it is it breathing.
Because its nostrils are closed all year round, its sense of smell has long since deteriorated. I only talked about the role of one nostril of the sperm whale earlier, but what about the other nostril? Since the sperm whale must have plenty of air to dive into the deep sea, its other nostril has evolved to act as a reservoir of air and communicates with its lungs.
At the same time, in order to ensure the maintenance of air pressure in the body, its right nostril is always closed. This unique approach is the result of the long-term evolution of sperm whales under the deep sea.

The sperm whale is a huge mammal in the ocean, and the sperm whale has formed a left nostril to breathe, the right nostril to store air, and the right nostril to be occluded.

There is a viscous lumpy substance called ambergris in the small intestine of sperm whale, the fragrance of ambergris is clear and gentle, containing musk scent, and slightly with soil incense, seaweed incense, wood fragrance and moss fragrance, which is used as a perfume fixative, hence the name.
Ambergris, also known as dragon's belly (also known as "grey amber" in the West), is a solid wax-like flammable substance that is dark gray or black in color, with its unique sweet earthy aroma (similar to the smell of isopropyl alcohol).
Some sperm whales spit out ambergris, others excrete it from the intestines, and only a small number of sperm whales keep it in their bodies. Ambergris discharged into the sea is light black at first, but gradually turns gray, light gray, and finally white under the action of the seawater. Historically, people mainly used it as a fixative for perfumes.
Since ancient times, ambergris has been used as a high-grade spice, and the fragrance company graded the acquired ambergris, ground it into a very fine powder, dissolved it in alcohol, and then prepared it into a 5% concentration ambergris solution for the preparation of perfumes.
Or used as a fixative (a spice that can make the aroma of the flavor more stable and volatilize slowly, and is an important part of the flavor). Therefore, ambergris is expensive, almost equivalent to it.

Sperm whales can make sounds.
The sperm whale is the largest of the toothed whales, with a very large head and a blunt front, so it is also called the giant whale, also known as the true beetle whale, and it mainly inhabits the sea area between 70 degrees north and south latitudes. It is also one of the loudest animals on Earth, squeaking, tapping and staccato clicks to communicate with their own kind, ranging from a meter to hundreds of kilometers away.
According to studies, sperm whales can emit sounds of up to 230 decibels underwater, which makes him the loudest animal in the world. It lasts 15 to 30 milliseconds and can be heard in water up to 10 miles away. The human ear cannot tolerate this sound.
Sperm whale habits:
Sperm whales like to live in groups, often by a small number of male whales and large groups of female whales, calves form dozens of more than one, even two or three hundred large groups, every year because of reproduction and foraging for north-south migration, its swimming speed is very fast, up to more than ten nautical miles per hour, and sperm whales have excellent diving ability, diving up to 2200 meters, and can stay underwater for two hours.
Because sperm whales have long branches during diving, they are unlikely to be seen on the surface, but their special shape and jets make them not easy to be confused with other large cetaceans. Between dives, sperm whales will float or swim slowly on the surface of the sea, resembling giant driftwood. The jet is about 45 degrees to the left, low and tree-like. There are often movements of jumping to hit the waves or whale tails hitting the waves.
Long-term stable females form the core of the sperm whale community, with small groups of up to 12 adult females, accompanied by their female and young male offspring, generally swimming at speeds of 5 to 3 knots per hour and 7-12 nautical miles when frightened. Older males with a length of 12 to 17 meters are more likely to swim alone in the ocean, and it is rare to find communication lasting more than one day. Whole pods of sperm whales sometimes run aground on the beach.

After my friend x whale research expert said:
Sperm whales rely on a rare ingredient in DNA chemicals in the eyes called "ambergris".
In fact, everyone thinks that sperm whales don't have eyes, your speculation is wrong, you can know by looking closely at sperm whales.
What is ambergris?
It supports the first floor.

If this society is full of good people, the standards of bad people will be automatically raised, for example, people who don't study hard are bad people, people who don't tell the truth are bad people, and bad people will still emerge in endlessly, because this society needs to belittle some people too much to find the survival value of the vast majority of people.
A friend is the person you want to talk to and he can listen quietly, or the person you want to share with and get his help when you are happy and frustrated, in short, having a friend who is worthy of your trust and does not step on your back, it is enough for you to use it for a lifetime, and you don't have to ask too much.
Hello, first of all, we might as well make clear the role of the reversing lights, of course, the reversing lights are installed in the rear of the car, which are used to illuminate the road surface behind the car when reversing, and play a role in warning the vehicles and pedestrians behind the car. However, many car owners have found that their car has only one reversing light, which looks so awkward. >>>More
