Adaptions in Ectothermic and Endothermic Animals to Extreme Climates

Body temperature and endothermic animals adapt to extreme climates First you need to understand what body temperature and endothermic animals are. Animals have different thermoregulatory capacity (temperature regulation). We sometimes use the word "cold blood" or "warm blood". Most reptiles feel cold, and mammals and birds often feel warm. A more accurate explanation can be made by using the terms "multi-temperature" and "isothermal". Body temperature is relatively variable, and the thermostat's body temperature is relatively constant.

A salient feature between external heat and endotherm is that the endotherm is able to regulate the temperature using a feedback mechanism including the hypothalamus, which is a physiological adaptation. Since the external temperature can not do this, their adaptability is often dominated by behavior and structure.

Animals that maintain constant body temperature in the face of environmental changes are called endotherms. These animals generate internal heat so that cell processes continue to work optimally in cold environments, so you can maintain active animal levels. Animals are stored or dissipated in various ways. Endothermic animals have some form of insulation. There are fur, fat and feathers. Animals with thicker furs and feathers will form an insulation layer of air between the skin and internal organs. Polar bears and seals live and swim below freezing while maintaining a constant warm body temperature. For example, when polar beans fall asleep in cold weather, they use fluffy tails as extra insulation. Mammals may raise body temperature by shaking, but this is an unintentional increase in muscle activity.

Reptiles are animals that change body temperature and body temperature. Because of its limited ability to control body temperature, body temperature is usually limited to certain places. However, except for Heterocephalus glaber, mammals are endothermic and thermostat. This provides the advantage for them to explore various environments.

Almost all mammals are endothermic ("warm-blooded animals"). Most mammals also have hair to help keep the body warm. Like birds, mammals can feed and hunt under the weather and climate, and they are too cold for warm ("cold blood") reptiles and insects. As endotherms require adequate food energy, mammals consume more food per unit body weight than most reptiles. Small insecticidal mammals are surprisingly large in size. As a rare exception, bare moles generate little metabolic fever, so it is considered a manipulable temperature variable furnace. Because birds are also endothermic, endotherm is not unique to mammals.
