Snakes that give birth to their young without laying eggs are called viviparous. We will be looking at how snakes lay egg along with other fascinating topics like how many eggs a snake can lay and frequency of reproduction. Other snakes have no eggs involved at all. This is because they come from warmer climates where the winters are not cold enough to necessitate this behavior. If the female has more than one clutch per year, the first clutch will probably be the biggest. Some species of oviparous snakes, such as ball pythons, will incubate their eggs until they hatch. They mate around May. So, How Do Snakes Get in the House? One reason is because there’s a survival advantage in giving birth to live young rather than laying eggs. Carrying eggs, before delivering live baby snakes. Snakes lay eggs and give birth, but it depends on the species. They are born with an instinct to survive. When the babies are fully developed, the mother gives birth to them as ovoviviparous snakes do. Reticulated pythons tend to lay the most eggs at once, primarily due to their extreme size. However, the mother does not lay the eggs outside of her body for the babies to finish developing. In some viviparous snakes, a yolk sac is also present alongside the placenta. This allows them to carry the eggs with them and then give birth to live young. There are certain people who keep snakes as pets and have no idea that their female snake is pregnant, as it can sometimes be difficult to recognize the signs until it gives birth.

Alternatively, you have species of snakes that give birth to live baby snakes. Rat snakes are a common type of snake found throughout the U.S. The young snakes hatch out of their eggs while still inside their mother, and she then gives birth to them. Ball Python Eggs Look Deflated? However, some species may lay two or even three clutches. They are gravid for around 4 months, during which time the babies develop fully inside the mother’s oviducts. Over 70% of snakes lay eggs, including adders, cobras, rat snakes and grass snakes. Species, such as rattlesnakes, are ovoviviparous. live birth producing (Viviparous) or Ovoviviparous (combination of the two). Around 70% of all snake species are egg-laying. The young stay with their mother in her den for just over a week, before heading into the world alone. Here’s more information about snakes that lay eggs and snakes that don’t lay eggs. An example of a snake which reproduces this way is the Brahminy blind snake, a tiny snake native to Africa and Asia. Again, this occurs 1-2x per year, around June-August, but these baby snakes typically enter the world alone. Either way, the number of eggs laid in one sitting is known as a ‘clutch’ of eggs. They grow a protective shell, and a yolk from which the babies absorb nutrients. This is called ovoviviparous. Two of the most common species of rat snake include corn snakes and black rat snakes (also known as black snakes). Basically the eggs will hatch inside of the female and the baby snakes eventually emerge fully formed and active with no shell at all.

At other times, snake mothers will protect their eggs from predators by circling the eggs. You would therefore expect 1-2 clutches of eggs from egg-laying species, or 1-2 litters from live birth producing species. Snakes can lay on average, anywhere from 2 eggs all the way to 80 eggs at a time. Do snakes lay eggs? There is no way of telling how many eggs survive, but if the mother does not find a warm place to lay her eggs, she will do it anywhere, in which case the eggs will be left to die. In certain species (like the Copperhead), they are known to be somewhere between the two; carrying eggs that they sometimes lay and at other times delivering live young from such eggs. Ball pythons will lay between 3 to 13 eggs, whereas reticulated pythons can lay between 20 and 80 per clutch. While in these environments, snakes may seek shelter in tree hollows, under logs, leaf litter, underground holes, rock outcroppings and/or burrows that have been abandoned by other animals.

If there’s anything you feel we’ve missed in this article about “do garter snakes lay eggs?” Please shoot us a message or leave a comment so we can check it out. While no exact date can be identified for when mating begins/birthing ends, snakes have an instinctual and biologically driven mechanism which means these times of the year are routinely followed. With a lot of questions on my mind, I decided to conduct some research into the topic. Some snakes can leave their eggs to be incubated by the warm earth after being buried, but other mothers are required in the process further. Some species of snake, such as rattlesnakes, can store sperm inside their bodies for later use. These snakes live in colder climates where eggs would not incubate as well. Most species look for a warm and protected or hidden place to lay their eggs. The king cobra builds a nest of leaves and other vegetation above ground, and guards it until shortly before the eggs hatch. The mother uses her body as a safe place for the babies to develop.
