When you think of reptiles, many people probably think of snakes.
It’s an animal that can easily be divided into likes and dislikes. Recently, the number of people who keep them as pets is also increasing. Let’s explore what kind of charm snakes have!
～ Basic information. ～
Smallest species. Blind snakes. Length:約10㎝ weight:not clear.
Largest species. Anaconda. Length:約10m weight:about 250㎏.
Snakes are found in many parts of the world, with around 3,000 species.
It is surprising how many there are.
Snakes move by wriggling their bodies since they have no legs.
This movement is called “Dutch roll.”
Why can snakes move their bodies so sinuously and flexibly?
The reason is that the snake’s spine is made up of many small bones that allow the entire body to move flexibly.
The number of vertebrae is usually around 100-200, but larger snakes can have up to 500 vertebrae.
Snakes have a lot of vertebrae.
So why can snakes move forward just by wriggling?
The secret lies in the scales on the snake’s body.
In fact, there are small hooks on the edges of the scales that allow them to grip the ground and move forward.
Snakes are included in poikilothermic animals.
What are poikilothermic animals?
Poikilothermic animals are animals whose body temperature is affected by the temperature of their surroundings.
When the temperature is low, their body temperature drops, and when the temperature is high, their body temperature rises.
Living things can move around because they have energy in the form of body heat.
However, in cold regions, they lose heat and consume all their energy and die from freezing.
In areas where it is cold during certain seasons, snakes cannot move around.
Therefore, many species of snakes live in warm regions.
They hibernate until warm weather returns.
Poikilothermic animals have a weakness in that they are vulnerable to changes in temperature, but on the other hand, they are strong against hunger.
Depending on the species of snake and the food they eat, they can live without eating for several days to several months.
Snake reproduction varies greatly depending on the species of baby snake, such as the season and duration of mating.
In the case of snakes that inhabit Japan, mating takes place around May or June after winter.
The way of mating is that the male and female intertwine with each other and finish it in a short time.
It is said that the time is short because they become defenseless during mating.
For larger species of snakes like anacondas, multiple males compete for one female.
The competition for females can last for two to four weeks.
They must fight fiercely to leave offspring.
A maniacal animal in pet breeding.
If you want to keep rare animals as pets, you may need to follow the laws established by your country. This time, I will introduce whether you can keep snakes at home in Japan.
There are still few people who keep snakes as pets.
It may be because they feel dangerous due to the image of biting or having poison.
However, once you know the charm, you will be captivated.
We will introduce how to keep snakes as pets.
What should I feed them?
Since snakes are carnivorous, they eat mice, bird chicks, reptiles, etc.
For pet snakes, I think many owners give them frozen mice as food.
There are different sizes of mice for food, so be sure to check before purchasing.
Since it is sold frozen, it needs to be thawed before feeding.
Thawing is easy.
Put the frozen mouse in a plastic bag and put it in water at about 40 degrees Celsius to thaw it.
Feed the snake by holding the food with long tweezers and shaking it in front of the snake’s eyes.
Never try to hand it over.
This is because you may be bitten by mistake when the snake confuses you with food. The frequency of feeding is about twice a week until the age of 2 years old, and once a week after that.
About the breeding environment.
There are three points to keep in mind when breeding.
When keeping multiple animals, separate the cages.
If you put multiple snakes in one cage, there is a risk of fighting.
If you want to keep multiple snakes, keep them in separate cages.
Let’s take good measures against desertion.
Snakes can easily escape if there are holes or gaps in the cage.
It is necessary to take measures to prevent escape from the cage itself, but it is also necessary to check that they do not escape from the room where they are kept.
Look for a veterinary clinic that specializes in exotics.
There are few animal hospitals that can examine snakes.
If you look for one before you start keeping them, you can keep them with peace of mind in case of an emergency.
Why do snakes sleep with their eyes open?
The reason why snakes sleep with their eyes open is that they do not have eyelids.
Do their eyes dry out if they are open all the time?
In fact, the surface of a snake’s eyeball is covered with scales that form a membrane.
Therefore, it is okay to keep their eyes open.
Since snakes always keep their eyes open, it is difficult to tell when they are sleeping.
You have to observe changes in their expression to see if they are awake or not.
Even snake owners who keep them as pets find it difficult to tell if they are sleeping or not.
Why do snakes stick out their tongues so often?
The reason why snakes stick out and retract their tongues is that they have a function called the Jacobson’s organ on their tongue that can detect odors.
By touching their tongue to the air, they can smell.
Also, there is a reason why a snake’s tongue is split in two.
Just as humans have two nostrils, the part of the snake’s tongue that detects odors is split in two.
By being split left and right, they can also determine which direction the odor is coming from.
I told you that snakes can distinguish smells with their tongues, but do they also have noses like humans?
The role of a snake’s nose is to breathe air in and out. It does not have the ability to detect odors.
Where are snake ears?
Snakes do not seem to have ears.
The reason is that the earlobes and eardrums have degenerated, so snakes do not have ears.
However, they still have the ability to recognize sounds.
So how do they recognize sounds?
They recognize sounds by vibrations that are transmitted through their muscles and bones to their inner ears.
Why do snakes molt?
Many people may think that snakes shed their skin because their skin becomes tight as they grow and they need to shed it.
In fact, the substance called keratin accumulates on the outermost skin, and shedding occurs when keratin, like human keratin, floats up from the skin.
This keratin is the same substance as our hair and nails.
The fact that snakes shed their skin is evidence of good metabolism and health.
On the other hand, if they are unhealthy, incomplete shedding may occur.
This is a phenomenon in which shedding does not go well due to poor breeding environment or illness.
You can judge the physical condition of a snake by checking whether it is shedding properly.
When snakes are young, they shed their skin once every two weeks.
As they grow older, the frequency decreases, and large snakes may shed their skin only once a year.
How can snakes swallow large creatures?
The shape of a snake’s jaw is related to its ability to swallow large creatures.
The snake’s jaw is not connected as one but is divided into left and right structures.
This structure allows the snake to open its mouth wide when swallowing large prey.
What kind of snake has strong venom?
The snake species known for having strong venom is the ‘Black Mamba’.
It inhabits Africa and grows up to about 2-3 meters in length.
The Black Mamba is recognized as the most terrifying snake in the world because it has not only a large amount of venom but also venom that is immediately effective.
Although it has strong venom, it is timid and has a strong sense of caution.
How strong is the venom of the Black Mamba?
The venom of the Black Mamba is said to be about 60 times stronger than that of a pit viper.
If you are bitten and do not receive appropriate treatment immediately, you will die.
Therefore, many people die without receiving treatment in time.
