What is the Difference Between Warm-Blooded and Cold-Blooded Animals?

Temperature-changing animals (commonly known as cold-blooded animals) are animals other than mammals and birds. Most of the animals on the planet are temperature-changing animals. Temperature-changing animals Because animals do not have their own mechanism for regulating body temperature, they can only rely on their own behavior to regulate the release of body heat or absorb heat from the external environment to increase their body temperature.

Also called "cold-blooded animal". An animal whose body temperature changes with changes in ambient temperature. Animals such as reptiles, amphibians and fish ^[1]

Except for the Antarctic and North Pole, warming animals are distributed on various continents.

Animals whose body temperature changes as the outside temperature changes are called warming animals. In addition to birds and mammals, other animals

Can survive in conditions of large changes in the external environment or food supply. Because they require less energy to maintain body temperature and physiological functions. The energy from food can be used more for growth. Therefore, warming animals are more efficient at converting food to body growth than warming animals.

Although the number of warming animals in the same environment can be dozens of times that of warming animals, the adaptability of warming animals to the environment is weaker than that of warming animals. For example, a constant temperature animal can overcome the disadvantages of the environment and have longer time and extensive space to obtain food.

Temperature-varying animal effects

When the body temperature of the temperature-changing animal is at the optimum temperature of the enzyme, the enzyme activity is large; below this optimum temperature, the enzyme activity is low.

This could explain that the motile animals are less active than the thermostatic animals.

The body function of a constant temperature animal can be maximized at any time. The animal body's ability to reflect is related to the body temperature. When the body temperature is suitable, it will reflect alertness and strength. The body is stiff and it is difficult to come out to move, and the activities of the constant temperature animal will not be affected by the external temperature at any time.

The digestive system of a constant temperature animal has a stable digestive capacity, and many digestive enzymes can obtain the maximum degree of activity at the corresponding temperature, while the digestive system of a warming animal cannot digest well at any time.

Constant temperature animals are easier to adapt to the living environment and more prone to reproduction and survival than warming animals.

Examples of temperature-changing animals

The mosquito is a cold-blooded animal, so its metabolic process, life history, longevity, and reproductive nutrition cycle are all subject to the temperature of the environment.

fish

They cannot control their own temperature, but at low temperatures, they can slow down their metabolic processes and survive. The average temperature of most mosquito species is about 25-27 degrees. At a low temperature of 10 degrees or a high temperature exceeding 40 degrees, its development is completely stopped, and the mortality rate is very high. The respiratory organs of mosquitoes are the trachea system. Therefore, it is generally particularly sensitive to dryness, so indoor mosquitoes are often concentrated in a place with sufficient moisture, while exogenous mosquitoes mostly stay on plants near the ground. Therefore, proper rainfall and sunshine will accelerate the breeding of exophytic mosquitoes. It can be seen that the growth environment, temperature and rainfall of mosquitoes are the main factors affecting the survival of mosquitoes. Dengue fever needs vector mosquitoes to spread the virus, and Aedes aegypti and Aedes albopictus are the main culprits in the transmission of dengue virus in Taiwan. In other words, as long as there are Aedes aegypti and Aedes albopictus, we will be deeply threatened by dengue fever. Therefore, to eliminate dengue fever, we must first understand the type characteristics and ecological matters of Aedes aegypti and Aedes albopictus. And breeding environment ^[1] .
