The temperature in Antarctica is the lowest. Penguins live in Antarctica. Why are they not afraid of the cold?

Antarctica is the coldest place in the world and the only place without permanent residents at present. The lowest recorded temperature is -94.5℃. Penguins can live happily in such a cold environment. Scientists point out that penguins can be said to be the least afraid of cold birds in the world. They are covered with dense feathers, and the subcutaneous fat is 2 cm to 3 cm thick. This special "insulation device" ensures that they can live freely in the ice and snow.

Living in the frozen Antarctic, penguins are not afraid of cold, mainly because they have a special body structure and a complex temperature control system in their bodies. Penguin feathers are thick and dense, in the form of overlapping scales, just like roof tiles. Under these layers of "tiles", there is a thick layer of fluff, which is as warm as a down jacket.

Penguins are not afraid of cold. Penguins are not afraid of cold mainly because there is a layer of air between their feathers, which can effectively keep warm and isolate cold air from the body. There are 17 species of penguins in the world, most of which are in the southern hemisphere. Penguins have short wings and cannot fly. In the water, its wings can push it to swim quickly like paddling. Its feet are under its body, and it has webbed toes. Feathers are short and dense, which can reduce friction in water. These are all to make it swim faster.

Conclusion Antarctica is a continent with a total area of 6.5438+0.4 million square kilometers. In winter, there is a great difference in heating between the mainland and the ocean. Land can radiate more heat into space. In addition, most of the land in the Antarctic continent is in the Antarctic circle, and the average altitude of the Antarctic continent is 2350 meters, so the temperature in the Antarctic is much lower than that in the Arctic. The Arctic is an ice layer covering the ocean, and the flow of seawater can bring more heat. But the low temperature in Antarctica is actually sub-regional. In the land center, due to the influence of Antarctic mountain ice, it will block the warmer air flow from the ocean, so the central area is cold. The Russian weather station once measured the temperature in the central Antarctic at around -89℃, and according to the analysis of meteorological satellites, the lowest temperature in Antarctica can reach-100℃, but only in some places in the central region, not the entire Antarctic continent.
