Does Great White Shark Lay Eggs? Everything You Need To Know

From the classic movie “Jaws” to the Discovery Channel’s “Shark Week,” great white sharks have been a part of pop culture for decades. But beyond that, great white sharks fascinate us because they are mysterious creatures of the deep.

One of the greatest mysteries is whether or not great white sharks lay eggs. Pregnant female white sharks have been discovered with hundreds of unborn cubs in their bellies, but no one knows exactly how those unborn cubs got there.

In this article, we’ll look at what scientists know about the reproduction of great white sharks, what might be happening underwater, and uncover why this topic is so hotly debated!

Here’s the Answer: Do Great White Shark Lay Eggs?

Great white sharks are ovoviviparous, meaning they produce eggs that hatch inside the mother’s body. This is in contrast to oviparous shark species, which lay eggs outside of their bodies. The gestation for these eggs may be longer than 12 months, though the exact period is unknown.

Reproductive System of The Great White Shark

The great white shark has an incredibly impressive reproductive system. As an ovoviviparous species, their eggs develop and hatch in the uterus and continue to develop until birth.

The male’s sexual organ, called a “clasper,” is located on their pelvic fin, while the female has oviducts that lead to the womb, or “cloaca.”

For great whites, sexual maturity occurs at ages 26 for males and 33 for females. Also, a study by the Woods Hole Oceanographic Institution found that they can live for up to 70 years, which is very long.

Although it’s hard to pinpoint exact metrics due to conflicting reports, adults usually measure 3.4–4.0 m in length (for males) and 4.6–4.9 m in length (for females). They also have an average weight of 522–771 kg (1,151–1,700 lb), with mature females averaging 680–1,110 kg (1,500–2,450 lb).

At their maximum size, great white sharks can measure up to 6.1 m (20 ft) in length and weigh as much as 1,905 kg (4200 lb); some reports even suggest they could tip 2268 kg (5000 lb).

Mating Habits of The Great White Shark

The mating rituals of the great white shark are mysterious and largely unknown. It is believed that female sharks store sperm in their bodies, which is then used to fertilize eggs up to a year later. This is known as ovoviviparity; the eggs develop and hatch in the uterus while the development continues until birth.

Great white sharks typically mate in late spring or early summer, and they migrate to warmer waters to breed. During this time, males show aggressive behavior such as biting and ramming each other with their heads, competing for access to the females. The male’s sexual organ, known as the “clasper,” is located on their pelvic fin, while the female has oviducts that lead to the cloaca.

Once mating has taken place, female great whites may also lay eggs for their larger offspring instead of giving birth as smaller members of the species do. It is thought that these eggs are fertilized by stored sperm almost immediately after birth, with hatchlings appearing shortly after. Bigger great white sharks may even keep fertilized eggs in their bodies for extended periods until they hatch while still inside the mother shark.

How Do Female Great White Sharks Carry Their Young?

Female great white sharks employ a method called ovoviviparous reproduction to bring their young into the world., which involves the development of embryos within an egg that is held inside the mother’s body. Unlike other marine species, this egg is protected by a thin membrane, helping to keep it safe until the baby shark has fully matured.

The eggcase provides nourishment and oxygen to the embryo as it grows and matures, slowly breaking down so that when the time comes for the baby shark to leave its mother’s body, it can do so safely. The placenta of the mother shark gives the baby shark food and oxygen while it is still in the womb.

When it comes time for birth, the mother will release her young into the wild oceans, where they can begin their lives independently. This process ensures that female great whites have a successful reproductive cycle and are able to carry on their species through a well protected delivery system!

How Do Great White Sharks Give Birth?

Great white sharks give birth to their young in a process known as ovoviviparity. This is where the female shark retains the eggs in her body until they are ready to hatch, usually seeking out warmer waters for the birthing process.

Once these pups are born, they have specialized organs known as yolk sacs, which provide them with the nutrients they need in their first few weeks of life, while they still remain attached to their bodies. After several weeks pass by, these pups now have enough strength and independence to hunt for their own food.

Furthermore, great white shark mothers will continue providing protection and guidance for a few weeks after birth, until the pups are ready to live fully on their own without any maternal help in the open ocean.

What Are the Characteristics of Great White Shark Eggs?

The great white shark lays eggs that have unique characteristics, making them incredibly resilient and protective for the embryos inside. These eggs measure around 3 to 4 inches in length and are generally oval-shaped, with a leathery outer shell that is tough enough to protect the developing contents inside.

The eggshell also contains a yolk sac, which provides nutrition for the embryo, an oil droplet that helps keep it buoyant underwater, and several pores that enable oxygen to enter and exit. Furthermore, some species of great white shark have different colorations, ranging from light brown up to dark gray or black; this helps protect them by camouflaging the egg from any predators while it develops.

It’s clear how important these features of great white shark eggs are for keeping their embryos safe and letting them hatch into fully grown pups.

How Many Eggs Does a Female Great White Shark Lay?

Generally speaking, they will produce between 10-20 egg cases each season. These egg cases contain multiple embryos, which eventually hatch after around 12 months in their watery environment.

It is thought that only 1% of these young sharks make it to adulthood, which makes this magnificent animal’s life cycle very hard.

This survival rate explains why it takes so long for us to observe them in the wild, but despite our limited knowledge about great whites, scientists continue to explore their behavior, and conservation efforts remain ongoing worldwide.

Baby Great White Shark Size

When it comes to baby great white shark size, there are several interesting facts worth exploring. These include the initial length of a newborn shark, as well as how much they grow and what their diet is like. Let’s take a look at these topics in more detail:

  • Initial Length: Baby great whites typically measure between 24 and 30 inches long when born, with some specimens measuring up to 36 inches. They’re usually slender, with pointed snouts and wide caudal fins.
  • Growth Rate: After birth, young sharks can grow from one inch per week up to four feet each year! This makes them quite formidable predators, even at an early age. In addition, growth rates vary depending on the species of great white shark.
  • Diet: As for food sources, baby great whites rely mainly on fish such as herring or sardines but may also consume squid or other small marine animals if available. Additionally, juveniles tend to hunt in shallow waters near shorelines where prey is abundant.

As you can see, baby great whites have many distinguishing characteristics that make them fascinating creatures, not the least of which is their incredible rate of size growth over time!With further research into this topic, we’ll surely discover even more amazing things about these apex predators.

Do Great White Sharks Eat Their Babies?

In fact, great white sharks don’t typically eat their young. Instead, they lay eggs and abandon them until they hatch. Here are five interesting facts about how great whites reproduce:

Great whites mate in warm tropical waters during the late spring and summer months.

Females will lay between 10 and 30 leathery egg cases at a time.

The eggs take around 12 months to reach full maturity before hatching.

Sharks usually abandon the eggs after laying them, leaving the pups on their own once they’ve hatched.

Baby sharks feed off the yolk sacs attached to each individual egg within the purse for nourishment, as well as any other small fish nearby.

To ensure survival, baby sharks must quickly learn how to find food sources and protect themselves from potential predators, including adults of their own species. It’s clear that while great white sharks have adapted in many ways over millions of years, eating their babies isn’t one of those adaptations!


A baby great white shark is an incredible sight to behold, but it’s a long and complicated journey before they ever reach those depths. This article has given us a look at the various stages of life that these sharks go through and reminded us of the incredible maturation process that is involved. From eggs hidden deep in the shoreline to adolescent sharks swimming freely among oceanic waters, great white sharks have come a long way over millions of years of evolution.
