Warm and cold-blooded animals



The basis of the separation of animals into two groups as cold-blooded and warm-blooded animals is the energy source they use. Cold-blooded animals use heat sources outside their own body to maintain their metabolic function. Friendly animals keep the temperature of their indoor environment independent from the ambient temperature. This concerns not only the ability to produce heat, but also the ability to cool. Warmers control their body temperature by regulating their metabolic rate. Biologists call warm-blooded animals endothermic because heat is produced in their bodies. Although warm-blooded animals have to rely on their environment to control their body temperature, warm-blooded animals do this naturally. All mammals and birds with few exceptionsIt is warm; all reptiles, insects, spiders, amphibians and fish are cold-blooded. Whether an animal is hot or cold is dependent on body temperature.
Warm-blooded creatures such as mammals and birds try to keep their internal temperatures constant. They do this in a cool environment, creating heat and cooling themselves in a warmer environment. To produce heat, warm-blooded animals convert the nutrients they eat into energy. In order to keep the body temperature constant, they should eat a lot of food compared to cold-blooded animals. Only a small fraction of the foods consumed by a warm-blooded animal are converted into body mass. The rest is used to create a constant body temperature. Cold-blooded organisms take the temperature of their environment. While their environment is cold, their body temperature is low and their body temperature is high while their environment is warm. In warm environments cold-blooded animals may be warmer than warm-blooded animals. Cold-blooded animals are much more active in hot environments and slower in cold environments. This is due to the fact that muscle activity is accelerated when the environment is hot, and it is due to slowing chemical reactions when the environment is cold. A cold-blooded animal's body mass conversion is more than a warm-blooded animal.

Staying Cool and Keeping Warm

To keep cool, warm-blooded animals lose heat by sweat and evaporation of water. They can also cool off by moving to a shaded area or getting wet. Only mammals can sweat. Primates such as humans, monkeys and monkeys have sweat glands all over their bodies. In dogs and cats, sweat glands are only on the soles of the feet. Whales are mammals without sweat glands. They do not need sweat glands because they live in water. If large mammals overheat, they may have difficulty in cooling. Therefore, for example, elephants have large and thin ears that will quickly lose heat. Mammals have hair, fur or fat, and birds have hairs that help keep them warm. Many mammals have thick fur layers that keep them warm in winter. Most hairs are poured in summer to help them maintain body temperatures. Warmer animals have much more heat if the environment is too cold and internal temperatures have fallento produce. Some warm-blooded animals, especially birds, migrate to warmer areas in the cold than in winter.
Cold-blooded animals usually want to warm up and soak up their metabolism. While sunbathing, the reptiles extend perpendicular to the direction of the sun to maximize the sunlight falling on their skin. It also expands the chest cages to increase surface areas and darkens the skin to absorb more heat. When a reptile gets too hot, it extends parallel to the sun's rays, enters a shaded area, opens its mouth wide, opens its skin or is buried in cool soil. Some cold-blooded animals, such as bees or dragonflies, tremble to stay warm in a cold environment. Fish that live in cold winter regions are transported to deeper water during the cold months or migrate to warmer water. Some fish have a special protein that acts as antifreeze to help their blood survive in very cold waters.
Snakes, lizards, frogs, salamanders, and most turtles are hibernating during the cold winter months. Some insects die when they are very cold, but others survive by migrating to warmer areas or by going to the bottom of the ground. Honey bees remain hot by staying together and moving their wings to produce heat.

Advantages and Disadvantages of Warmth and Coolness

Being friendly gives you many advantages to live. Warm-blooded creatures can remain active in cold environments where cold-blooded animals can barely move. The warm-blooded animals can live in the polar regions or in almost all parts of the world as in the high mountains where even the cold-blooded creatures will have to survive. Warm-blooded creatures are more active, food can search for food, temperature difference can easily defend itself in many environments. A cold-blooded animal can only do this when it is warm enough. The activity of cold-blooded animals depends on the temperature of their environment. For example, a reptile raises its temperature first, then fished. Cold-blooded animals should also be active and warm to seek and breed their husbands.
Being cold-blooded also has advantages. Cold-blooded animals use less energy to survive than warm-blooded animals. Mammals and birds need food and energy more than a cold-blooded woman. The reason is warm
In animals, heat loss from the body is proportional to the body surface area and the masses of the heat produced in their bodies. The proportion of an animal with the mass of the body surface is less than the body size. This means that larger-bodied warm-blooded animals can produce more heat than they release, and they can more easily stabilize body temperatures. Small-bodied people are easier to lose heat. It is not difficult to stay warm as a larger body. Therefore, the body of warm-blooded animals is not usually too small. Otherwise they lose heat faster than they can produce.


Small mammals should be fed too often to survive, because they need more energy to maintain the stability of the body temperature. They should also eat high-energy foods such as fruit, seeds and insects and even other small mammals. Larger mammals can obtain energy by eating lower energy foods or eating less frequently. Reptiles have an advantage in an environment where there is little food like desert. Cold-blooded animals are more efficient than they need to eat and burn calories to keep their body temperature stable, and they can survive longer without food. Many cold-blooded animals try to keep body temperatures as low as possible when food is scarce.
Another disadvantage of being warm-blooded is that their warm-blooded bodies provide a beautiful environment for the survival of viruses, bacteria and parasites. Mammals and birds tend to experience more problems with these invaders and infections than reptiles with ever-changing body temperatures. It is an advantage, however, that mammals and birds have developed a stronger immune system than cold-blooded animals. The immune system of a reptile is more effective when animals are warmer, but because bacteria grow probably more slowly at low temperatures, they sometimes reduce body temperatures when they catch infection.

Hot and Cold

Some animals do not fall into exactly the categories of hot or cold-blooded animals. For example, bats are mammals that cannot maintain body temperature and cannot cool down when they are not active.
The body temperature of the echasses usually ranges from 25 to 37 degrees Celsius and is difficult to cool. Mole mice are another mammalian group that cannot regulate body temperatures, but because they live underground, their environment does not change much.
Some warm-blooded animals, such as bears, mountain rats, squirrels and bats, are hibernating during the cold winter months. During the winter sleep, these animals live with stored body fats and can lower body temperatures down to 10 degrees Celsius.
It is an insect that can go beyond body temperature when it is flying because of huge wing muscles producing heat during hawk moth use. The bees are another example of insects that can move their wings rapidly to produce heat and increase their body temperature above the ambient temperature.
