Why are snakes cold blooded Are snakes cold blooded?

Cold-Blooded Animals "Cold-blooded animals" are the colloquial term for "ectotherms".

Animals whose body temperature changes with the change of outside temperature are called ectotherms. With the exception of birds and mammals, all other animals are ectotherms. Their body temperature changes with the environment.

This does not mean that they must not control their body temperature, they can change their body temperature by seeking a cool or warm environment, but they cannot directly control their body temperature, that is, they lack the physiological function to maintain a certain body temperature.

Because ectotherms do not need to use their own energy to warm or cool down, ectotherms only need 1 10-1 3 energy to survive compared to homeotherms, and therefore only need relatively little food. Because they are more likely to accumulate enough energy, ectotherms also have a shorter breeding period. Cold-blooded advantages:

It can survive under 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, cold-blooded animals are more efficient at converting food into body growth than homeothermic animals.

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

Ectothermic animals are animals that do not have an internal temperature control system, and they cannot maintain a constant temperature (cannot maintain a constant body temperature) in their own body, and they must maintain their body temperature by irradiating the sun, or regulate their body temperature by acting. So ectotherms are generally not nocturnal. 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.

Cold-blooded animals refer to reptiles, amphibians and fish and other animals, their body temperature will change with the change of environmental temperature, so they are also called ectotherms Cold-blooded animals because of the poor mechanism of body temperature regulation, so the blood temperature will change with the change of environmental temperature. When it's cold, their blood temperature is lower, and when it's hot, it's higher.

Snakes are cold-blooded animals.

Without an internal temperature control system, the body cannot maintain a constant temperature in the body, and the body temperature must be maintained by irradiating the sun, or the body temperature can be regulated by action. Body temperature changes with the change of the outside temperature. So snakes are cold-blooded animals.

Snakes, belonging to the reptilian spike class, suborder snakes, are true terrestrial vertebrates. Snakes prefer shady, damp, inaccessible, overgrown, wooded, hollows of fir trees or piles of rocks, with firewood stacks and ancient earthen walls, and rich in bait.

The snake has a peculiar shape and color, is covered with scales, has a high head and neck, swings its body and tail, travels quickly, chirps in a mate, and transitions in the water, and it is really difficult to cute Snake food includes rats, frogs, birds, etc. The weather is mild, and they occasionally come out to bask in the sun, sometimes they eat, and they hibernate in the winter.

Snakes start preparing the fat they need to survive the winter in the fall, and they will hoard as much food as possible for the winter. Snakes will choose caves, tree holes and rock crevices in dry areas as shelter to hibernate in high areas. During hibernation, there are often dozens or hundreds of snakes of the same or different species that congregate together to spend the winter.

Advantages of cold-blooded animals:

1. It can survive under the condition that the external environment or food supply changes greatly.

2. It only requires less energy to maintain body temperature and physiological functions.

Snakes are cold-blooded animals and have a habit of hibernating. Cold-blooded animals are animals that do not have a thermoregulatory system in their bodies.

If it can't maintain a constant temperature in the body, it needs to maintain its body temperature by basking in the sun, or regulate its body temperature by acting.

Vertebrates, reptiles, and amphibians are the main animals, and larger cold-blooded animals such as snakes, crocodiles, etc., need to bask in the sun in the morning to raise their body temperature so that they can be active, so they are almost all active during the day and rest at night. Snakes are carnivores and eat many types of animals, ranging from invertebrates to various vertebrates.

Cold-blooded animals, also known as ectotherms, refer to animals whose body temperature changes with the change of environmental temperature. With the exception of birds and mammals, all other animals are ectotherms. Common ones are fish, snakes, frogs, lizards, crocodiles, turtles, etc.

Ectothermic animals do not have an internal temperature control system, so they need to maintain their body temperature through solar irradiation or other means, or regulate their body temperature by action. Therefore, ectotherms generally do not move at night, such as snakes, crocodiles and other larger cold-blooded animals need to bask in the sun in the morning to raise their body temperature. When the temperature of the external environment increases, the metabolic rate of the animal increases accordingly, and the body temperature also rises graduallyWhen 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, swim to warm waters, or burrow underground or burrowing to hibernate.
