Snakes have two different ways of producing young, either by laying eggs or live birth. The snakes that have live birth do not carry their babies in the womb like mammals; rather, they grow their babies inside of their bodies as if they were in eggs.
Viviparous snakes reproduce without any eggs involved – they nourish their internally developing young in a similar way to mammals, through a placenta and a yolk sac, and then give live birth, birthing a litter of baby snakes that can range in size from 1 or 2 all the way to 150 4!
Parthenogenesis, or virgin birth, is possible, and female snakes that have never encountered a male can lay viable eggs. This happens in the wild when there is no access to male snakes, and live offspring can be produced even from this non-coupling.
In Victoria, Brown Snakes are found over most areas, excluding higher altitudes. Brown Snakes mate in spring, after males aggressively compete for a chance with a female. Females lay between 20-40 eggs in a clutch. Their eggs are oval in shape and have a leathery shell.

Reintroduce your snakes for a few days in succession until the female looks like she has lost interest in the male. She will be producing eggs at this point. After this, all you have to do is wait for her to lay eggs or birth live babies. The gestation period is generally 28 to 45 days.
Creating offspring without sperm
Females of these species, which include some wasps, crustaceans and lizards, reproduce only through parthenogenesis and are called obligate parthenogens.
A new study from South Africa observed wild snake mothers protecting and warming their young for weeks after they emerged from eggs.
Not all snakes breed in a ball, though these reptiles certainly aren't monogamous breeders that mate for life. Females of species that don't form mating knots still give off pheromones that attract males, but the first to reach her will often engage in non-lethal combat to prove their value as a mate.
How Long Do Snakes Live? Snakes reach sexual maturity within two to four years, depending on the species and living conditions. In perfect conditions, adult snakes live anywhere from 20 to 30 years, with natural predators and the encroachment of humans severely limiting the number of years most snakes live.
The Diamond Python are egg laying snakes, and live in a variety of habitats, including heaths, woodland, forest and urban areas. They also are known to occupy the roof space of suburban homes, living on mice and rats.
Robert Powell, a biology professor and snake expert at Avila University in Kansas City, said the Brahminy blind snake – a small burrowing animal native to southeast Asia commonly known as the flowerpot snake – has long been the only known snake that routinely reproduces without a male's contribution.
During copulation, the male inserts one hemipenis into the cloaca of the female to transfer his sperm. Female snakes can become pregnant immediately or choose to delay fertilization, storing sperm for up to five years.
Seahorses and their close relatives, sea dragons, are the only species in which the male gets pregnant and gives birth. Male seahorses and sea dragons get pregnant and bear young—a unique adaptation in the animal kingdom. Seahorses are members of the pipefish family.
Probably not. Ethical considerations preclude definitive research on the subject, but it's safe to say that human DNA has become so different from that of other animals that interbreeding would likely be impossible.
Wild house mice rely on specially evolved proteins in their urine to sniff out and avoid mating with their close relatives. In many social species the trick is that one sex, usually the female, leaves the group at adolescence. That way they can't mate with their own family.
Snakes do not bite pregnant women. If you speak the name of a woman who is pregnant three times, then the snake stays quiet, waiting. Pregnant women control snakes. If a pregnant woman makes a knot in her skirt, the snake becomes calm and does not bite.
The length of gestation varies from species to species. The shortest known gestation is that of the Virginian opossum, about 12 days, and the longest that of the Indian elephant, about 22 months.
They are either white, off-white, or sometimes beige. Snake eggs aren't hard like birds' eggs. Their surface is flexible and leathery. Some snake eggs even stick together.
For example, baby snakes are called snakelets, just like baby pigs are called piglets. Although the term is pretty straightforward, we think it has a cute ring to it.
Now you know that snakes don't give birth through their mouths. Snakes can develop and deliver their young one of three ways: laying eggs, live birth, or a combination of the two. If you see a snake with babies in her mouth, she is just protecting or carrying them.
Many sharks are viviparous, meaning they give birth to live young. Like all sharks, species such as blue, bull, and hammerhead sharks rely at first on a yolk sac for nutrition. But they also develop a placental connection similar to a mammal's umbilical cord.
