These Animals Don't Care That It's Freezing Outside
Animals are very successful in adapting to the conditions of their living environment. The reason why animals can adapt to ambient conditions where the weather is too cold or too hot is that they can regulate their body temperature.
The body temperatures of warm-blooded creatures, such as mammals, are constant regardless of the temperature of their environment. Warm-blooded creatures need a lot of energy to keep their body temperature constant. Therefore, the nutritional requirement is of vital importance for warm-blooded creatures. Body temperatures of cold-blooded creatures may vary depending on the ambient temperature. However, this does not mean that they can survive in all conditions. Because the speed of biochemical reactions that sustain life usually decreases as the temperature decreases. In addition, a natural anti-freeze mechanism takes place in these creatures.
