With that in mind, great white shark reproduction can only occur during a relatively short timeframe. Because of the long gestation period, it’s possible that female great whites give birth every other year, taking some time to rest after mating.
Do sharks give birth to live young? There are more viviparous shark species - which bear live young - than sharks that lay eggs. But throughout Earth's oceans, viviparity occurs in a variety of forms. Whale sharks (Rhincodon typus) are the largest species of shark. Although these animals produce eggs, they don't lay them. Carpet sharks. The bamboo sharks (Hemiscylliidae) and the zebra shark (Stegostomatidae) lay eggs on the bottom, while the other carpet sharks give live birth.The egg cases are oval and covered with adhesive fibers that serve to secure them to the bottom.

Like a human embryo, the baby sharks receive nutrients inside the womb from an umbilical cord. The baby sharks also receive oxygen from the mother shark's bloodstream via the ...
Some sharks lay eggs, while others give live birth. Great white sharks gestate their pups for a year before giving birth – that's longer than humans. Between 2 to 12 babies are born at a time. Great whites can live up to 60 years, maybe more. They give birth to both depending on the species, most sharks reproduce through ovoviviparous means- they have eggs which hatch inside the mother and then they give birth to live young- almost a cross between human birth and chickens laying an egg.

This fertilization behavior means that male sharks release sperm inside female sharks to fertilize eggs. Only 1 or 2 eggs are fertilized at a time, which contributes to slow population growth and recovery. The difference in shark reproductive behavior is that some sharks give birth to live babies. These sharks are known as viviparous. Only a few sharks, like cat sharks, lay eggs. But look out! A whole bunch of sharks give birth to live baby sharks, called pups. Mako sharks, bull sharks, lemon sharks, and blue sharks are a few examples of sharks that are born live.
Sharks that are not born from eggs in egg cases are born alive. There are two ways in which live birth reproduction is accomplished among sharks. The most common way is called ovoviviparity. Ovoviviparous sharks have eggs that develop within the mother's body. The eggs are fertilized internally and the developing sharks are nourished by the egg ... Actually, it's not a true live birth... they essentially lay eggs inside the female, they hatch like normal fish, *then* leave the female's body. But there is no placenta like with mammals. It's called "ovoviviparious". But they also lay eggs in "cases"; you might find the weird things washed up on a beach. Whales, seals, dolphins, and otters all give live births. Some sharks give live birth, some lay eggs, and some give live birth to "pups" that grew in eggs in the uterus and then are hatched/born live; it depends on the species.

These young sharks get their nourishment from the yolk sac. This is similar to sharks that form in egg cases, but the sharks are born live. A shark can be born three different ways, including live birth, hatching from an egg, and an egg-and-live-birth combination. Plus, in some shark species, you have to survive gestation without being eaten by your developing siblings. Not that you could tattle to Mom once you're out of the womb -- after birth, shark pups are pretty much on their own. Some shark species are oviparous, meaning they lay eggs. Others are viviparous and give birth to live young. Within these live-bearing species, some have a placenta just like human babies do, and others do not. In those cases, the shark embryos get their nutrition from a yolk sac or unfertilized egg capsules filled with yolk.
Sharks are divided into two groups: those that lay eggs (oviparous), and those that give live birth (viviparous). Known as a mermaid’s purse, the egg sac of oviparous sharks allows the pup to develop. Note the long, curly tendrils that help the egg attach to seaweed and remain out of harm’s way until birth. Types of Sharks That Lay Eggs. Shark species that lay eggs include: Bamboo sharks, Carpet sharks, Horn (bullhead) sharks, and many cat sharks. Live-Bearing Sharks. About 60% of the shark species give birth to live young. This is called viviparity. In these sharks, the young remain in the mother’s uterus until they are born. In 2012, she was moved into a separate tank at the aquarium with no male sharks. In her new tank, Leonie continued to lay eggs whether they were fertilized or not, just like chickens do.
Oviparous sharks include the horn shark, catshark, Port Jackson shark, and swellshark. Viviparity. Viviparity is the gestation of young without the use of a traditional egg, and results in live birth. Viviparity in sharks can be placental or aplacental. Young are born fully formed and self-sufficient. Bull sharks give birth to live young. Sharks give birth in one of three ways. If they’re oviparous, they lay a sac full of eggs (called a “mermaid’s purse”), which attaches itself to a rock or other surface until the eggs are ready to hatch. If they’re viviparous, they gestate live shark pups and then give birth to them live.

Afterward, the shark pup is born. While they are s... Sharks either lay eggs or give live birth. Sharks deposit eggs through oviparity or give birth to live young through vivparity. Their fecundity, potential reproductive ability, ranges from 1-2 a year to a possible 300 produced by whale sharks.
Sharks reproduce both ways. 70% of sharks reproduce by live-birth. However, there are two methods of live-birth. The first method is Ovoviviparity, which most sharks do. Ovoviviparity is the mode of reproduction in animals in which the embryos develop inside eggs that are retained within the mother's body until they are ready to hatch. Sharks can have from 1 to 100 babies at a time, depending on the type of shark. The ones with pups that grow inside the mother have fewer babies at a time than sharks that lay eggs outside the body. Sharks do not care for their babies after they are born, but they do search for a safe place where they can lay their eggs or give birth.
(See "Evolution in Action: Lizard Moving from Eggs to Live Birth.") Only birds, turtles, and crocodilians bear no live young at all. ... In some sharks that bear live pups, ... Viviparity: Viviparous sharks carry the embryos through the entire gestation period and give birth to live shark pups, similar to how mammals give birth. Embryos are attached to their mother with a yolk sac placenta, which is how they receive their nutrition.
Do sharks lay eggs or give live birth? Sharks exhibit a great diversity in reproductive modes. There are oviparous (egg-laying) species and viviparous (live-bearing) species. Oviparous species lay eggs that develop and hatch outside the mother's body with no parental care after the eggs are laid. Which Snakes Give Birth to Live Young? So, which snakes give birth to live young? As mentioned above, both viviparous species (no eggs) and ovoviviparous species (egg retained inside the body) produce live and fully functional baby snakes. Most vipers, and all of the rattlesnakes, fall into this category.
Oviparity is birth from eggs, and in the case of sharks, the eggs are enclosed in natural, leathery egg cases, which offer some protection from predators during development. Shark pups born live, either viviparously or ovoviviparously, have already developed within the body of the mother to a defensible size and with a complete set of teeth. Live Bearing Sharks. The other 60% of shark species give birth to live young, rather than lay eggs. This is known as viviparity. In these species of sharks, the young remain in the mother’s uterus until they are born.

Ovoviviparous birth is an interesting shark birthing process that takes very little toll on the mother but is fatal to many young sharks. During Ovoviviparous shark birth, the mother never produces a placental sac but rather carries the young sharks alive in utero. The embryonic sharks feed on the egg yolk that produced them. Sharks are divided into two groups: those that lay eggs (oviparous), and those that give live birth (viviparous). Known as a mermaid’s purse, the egg sac of oviparous sharks allows the pup to develop. Note the long, curly tendrils that help the egg attach to seaweed and remain out of harm’s way until birth.
These sharks feed along areas that contain high densities of large zooplankton (i.e., small crustaceans, invertebrate larvae, and fish eggs and larvae). There is a theory that the basking shark feeds on the surface when plankton is abundant, then sheds its gill rakers and hibernates in deeper water during winter. Some sharks lay eggs, while others give live birth. Great white sharks gestate their pups for a year before giving birth – that’s longer than humans. Between 2 to 12 babies are born at a time. Great whites can live up to 60 years, maybe more. Most sharks are slow to grow and take a long time to mature.
