Why are people not cold blooded animals and what are cold blooded animals

Although humans are also advanced animals, there is still an essential difference between humans and animals.

Cold-blooded animals, in fact, refer to ectotherms. With the exception of mammals and birds, most of the animals on Earth are ectotherms. Common ectotherms are snakes, fish, lizards, insects, etc.

What is ectotherms

Ectothermic animals do not have a mechanism to regulate their body temperature in their bodies, and can only rely on their own behavior to regulate the emission of body heat or absorb heat from the external environment to increase their body temperature.

When the temperature of the external environment rises, the metabolic rate of the animal increases, and the body temperature gradually rises, and they passively leave the unfavorable environment; When the temperature of the external environment decreases, the metabolic rate of the animal also decreases, and the body temperature gradually decreases. So they either move to the sun to warm up their body temperature, or burrow into the ground or burrows to hibernate, or swim to warm waters, or hibernate in summer.

Advantages of ectotherms

Ectotherms can survive in conditions where the external environment or food supply changes greatly. Because they require less energy to maintain body temperature and physiology. The energy from food can be used for more growth.

As a result, ectotherms are more efficient at converting food into body growth than homeotherms.

Analysis: Cold-blooded animals.

Cold-blooded animals are animals that do not have an internal thermostat system. Generally, the body temperature is uneven, or the body temperature is adjusted by action. Larger cold-blooded animals such as snakes and crocodiles need to bask in the sun in the morning to raise their body temperature so that they can move, so they are almost always active during the day and rest at night.

Methods of temperature control include:

Snakes bask in the sun on stones.

Fish in the water to change to different depths.

Desert animals are buried in the sand during the day.

Insects flutter their wings to warm their flying muscles.

Because cold-blooded animals do not need to use their own energy to warm or cool down, cold-blooded animals of the same weight only need 1 10-1 3 energy to survive compared to warm-blooded animals, and therefore only need relatively little food for stupid rounds. Because they are more likely to accumulate enough energy, cold-blooded mascots also have a shorter breeding period.

Although cold-blooded animals can survive ten times as many as warm-blooded animals in the same environment, warm-blooded animals can most of the time drive cold-blooded animals to extinction because warm-blooded animals have more time to find food.
