Whether a snake reproduces through live birth or lays eggs, fertilization will always happen internally. There exist several reproduction modes in snakes, depending on the relationship between the zygote and the mother. 

For instance, there are some snake species such as the rattlesnake and most vipers, which are ovoviviparous. In this kind of snake, the eggs remain in the body after fertilization until they can hatch.

The yolk sac is primarily responsible for nourishing the embryo. During birth, the young ones emerge without a shell, which remains in the body. Ovoviviparous occur between the viviparous and oviparous; they have eggs and do give live birth.   

Viviparous snakes, on the other hand, give live birth without any involvement of the eggs at any stage. The sperms fertilize the ovum and embryo forms, just like in humans.

The embryo depends on the placenta, and maybe together with the yolk sac for nourishment. The placenta connects the fetus directly to the mother. Examples of snakes in this category are green Anaconda and boa constrictor. 

Another mode of reproduction in snakes is oviparity. Oviparous snakes lay eggs that hatch after about 2-3 months depending on different factors.

Examples of snakes laying eggs include; Cobras, Garden snakes, King snakes, and Mambas, among others. Some snake species abandon their eggs in hidden nests, which act as incubators. In contrast, most pythons will coil around the eggs after laying and guard them until they hatch. 

Typically, young snakes are independent, and the parents usually don’t provide parental care, unlike other animal species. It is clear now that snakes can give live birth, but how do they do that?

Do snakes give birth through their mouth, or how does the process take place?  How do live baby snakes emerge from the mother’s body?

It is not surprising that the majority of people may not know how a snake gives birth; they are not close to them anyway. In this article, we are going to learn every bit concerning reproduction in snakes.

How Long is a Snake Pregnant?

Pregnancy in snakes varies depending on the species, after which the snake gives birth. In this section, I’m going to reveal the different snake species and the length of time they remain pregnant.

Copperheads carry the pregnancy for 3-9 months, tiger snakes for about three months, black mamba for approximately three months, rattlesnakes for up to 167 days, and king cobra for 50-59 days. This is a list of some of the examples of poisonous snakes.

The following are examples of non-venomous snake gestation periods; rat snakes stay in pregnancy for 65-70 days, ball python between 44-54 days, and Anaconda for approximately 6-7 months.  

How can you tell whether a snake is pregnant or not? Various parameters will help you to know when a snake is pregnant.

Here are some examples of what to expect, a change in character, poor appetite, and shade seeking. Some snakes like the ball python will deny themselves food and prefer to guard and warm the eggs until they hatch.  

The males display the sperms to the females with the hemipenes’ help, and then fertilization occurs after ovulation. However, some snakes can show a rare case called parthenogenesis, where the female gets pregnant without copulation.

It may sound impossible, but the same shows to be real in a yellow-bellied water snake, though it’s uncommon. Polar bodies pretend to be sperms and fuses with the egg.  

Which Snakes Give Live Birth?

Both ovoviviparous and viviparous snakes give birth to live young ones during the end of the pregnancy period. These species differ depending on the interaction between the zygote and the mother during the gestation period.

Also, the number of litter is different from one species to the other. Some species give birth to a few juveniles, while others can produce up to 150 young snakes. The juveniles emerge with a thin membrane covering the body, and they use an egg tooth to tear the layer and come out. Below are snakes that give live birth.

Copperheads give live birth and give rise to even 10 young ones depending on the snake’s size, and they can deliver anywhere.

The impressive fact about these snakes is that if they breed during winter, they can store the sperms in the body until the season is over. After hibernation, fertilization takes place, and the gestation period begins. 

Tiger Snakes

Tiger snakes are high when it comes to reproduction. A single female can reproduce between 20-30 juveniles in one birth.

The snake usually births at the end of summer or when winter is around the corner. Don’t be surprised to see a tiger snake giving birth to 70 young ones.

Garter snakes

These snakes are ovoviviparous, can give rise to 3-98 baby snakes, and have a gestation period of 2-3 months. Before mating happens, garter snakes enter into the dormancy stage, and then breeding takes place immediately after they emerge from the dormancy stage.

Females seek food as soon as they come out from mating areas and prepare a place where they will give birth. Garter snakes can store male sperm for many years before fertilization.

Rattlesnakes produce live baby snakes after carrying the eggs inside the body. The females produce offspring once every three years.

Rattlesnakes also look after their babies for a little while. In a single birth, this snake can give rise to 8-10 babies. Baby snakes appear to be more hostile than adults, and they are born venomous.  

Boa constrictor

It is a viviparous snake that produces young ones measuring about 30-58 cm long. It has an average litter size of 25, and some snakes can have up to 65 babies.

Females can remain with sperms in their bodies for one year before ovulation. Baby snakes look after themselves from birth.

When producing live baby snakes, there are high chances of survival, unlike in oviparity, where the majority of snakes neglect their eggs. Other snakes that give live birth are green anacondas, venomous cobra, mambas, and adders.

The babies begin to move after they are born, and most of them are independent. The reproduction activities in snakes occur through the cloaca. Like chickens, snakes’ eggs emerge from the body through the cloaca, so are live babies. 

Do Snakes Give Birth Through their Mouth?

We know that a snake can give live birth. Now, the question is, do snakes give birth through their mouth? Snakes do not give birth through their mouth, nor do they lay eggs.

A snake can remove the eggs through the mouth when vomiting. It may steal the eggs from another snake or other animal species by swallowing.

However, in case someone catches them, they will throw up and remove the eggs to be able to escape freely. A snake can take a week to digest food. 

Moreover, snakes like pythons carry their babies with their mouths from one place to another when protecting them. A python gives explicit attention to its babies in early life, but the majority of the snakes abandon the young ones. 

Do Snakes Feed Their Young?

Snakes are distinctive creatures, and they express different behaviors opposite from other animals. How snakes behave with their babies is something that can make you raise a lot of questions.

It is only a few snakes such as Pitvipers and African rock pythons who care and feed their young. Most snakes don’t stay with their mothers, forcing the baby snakes to hunt on their own.

The primary reason why snakes portray such a behavior is that they swallow the entire prey during hunting. Therefore, it is difficult for a snake to preserve food for young ones.

The young snakes are born to be able to crawl, and they are capable of hunting small prey. The majority of snakes do not see or meet their mothers. The mothers give birth or lay eggs and will suddenly go away.


There are so many facts about snakes, and this review explains the reproduction modes in snakes and the various activities relating to the system. Snakes can either be egg layers or give live birth, but can they give birth through their mouth?

The simple answer to our question is that they don’t. You may encounter the snake with its baby in the mouth or even eggs, but it doesn’t mean they are giving birth.
