Mammal. It is the animal with the highest morphological structure and the most complete physiological function in the animal world. Compared to other animals, the most prominent feature of mammals is that they are viviparous and their young are fed with milk secreted by their mothers.

Mammals have fur to keep their body temperature constant and adapt to a variety of complex living environments.

Mammals have a well-developed brain, so they can produce more complex behaviors than other animals, and can constantly change their behavior to adapt to changes in the external environment. There are more than 4,000 species of mammals in the world, and although they are all highly evolved, they still have a lot in common: almost all mammals are warm-blooded, with a basically constant body temperature, and their bodies are covered with hair to protect their bodies, isolate them from heat and cold, and so on.

Although the nests of mammals are not as delicate as those of birds, they are varied and varied. Mole.

Underground caves tend to be up to 1 meter deep and more than 100 meters long; Most squirrels build their nests in tree cavities, but gray squirrels build their nests between branches at the top of trees; Female polar bear.

No, some mammals menstruate, cows, mares, camels, sows, ewes, etc., and some mammals go through estrous cycles.

Animals come to menstruation generally only 1-2 years a year, this period is the mating period of animals, so each different animal his mating period is not the same, generally in the spring. Animals usually have a menstrual leave for only 1-2 years a year.

This period is the mating period of the animal, so the mating period is different for each different animal, usually in the spring. According to scientific research, basically most female mammals will come to Aunt Qi.

Of course, the great aunts of different female creatures are not the same. For example, a great aunt who refers to a human woman can be called "menstruation", but other animals don't come once a month on time, so they have their own different names.

Causes of the appearance of menstruation:

This phenomenon usually occurs before a woman ovulates in order to make it easier for a fertilized egg to conceive after mating. So in the final analysis, the great aunt phenomenon is an auto-regulated behavior in the female body that is conducive to reproduction.

To explain it scientifically, it is the act of uterine cleansing. The uterine cleansing behavior is completely controlled by the hormones in the woman's body, which also explains why some women have irregular schedules that cause hormone secretion disorders to cause the aunt to be unpunctual. <>
