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.

live birth
Among animals, viviparity is development of the embryo inside the body of the mother. This is opposed to oviparity which is a reproductive mode in which females lay developing eggs that complete their development and hatch externally from the mother.

Do lemon sharks lay eggs?
There are over 500 species of shark living in waters around the world and the majority give birth to live young.The remainder are oviparous, meaning they lay eggs. Around 40 to 50 different shark species live permanently in or regularly visit the waters surrounding Britain.
Do hammerhead sharks lay eggs?
The lemon shark is viviparous, meaning it gives birth to live young rather than eggs. Embryos develop inside the mother for up to 12 months until the female seeks shelter in a shallow nursery during spring or summer to give birth. A litter of lemon sharks may be as large as 17 pups.
How do sharks lay spiral eggs?
Unlike many fish, hammerheads do not lay eggs. A female gives birth to live young. One litter can range from six to about 50 pups. When a hammerhead pup is born, its head is more rounded than its parents'.
Do sharks lay eggs yes or no?
And there's practical reasons for its bizarre shape. “When the Port Jackson shark lays an egg, she'll pick it up in her mouth and screw it into rocks and crevices to anchor it, so that they don't wash away and that's what gives them that shape,” explains Mark.
Do great sharks lay eggs?
Sharks employ two main reproductive strategies: oviparity and viviparity. Oviparous sharks lay eggs that develop and hatch outside the mother's body. In contrast, viviparous sharks retain the eggs inside their bodies, where the embryos develop until they are born.
Do tiger sharks lay eggs?
Great white sharks don't lay eggs. Instead, they are ovoviviparous, which means that the shark grows in an egg which is then hatched inside the mother. The mother then gives birth. While still in the womb, it isn't uncommon for a hatched shark to eat the other undeveloped eggs and even their unborn siblings.
Do zebra sharks lay eggs?
Tiger sharks mate via internal fertilization and give live birth to as many as 80 or more small young. Though they give live birth, tiger sharks do not connect to their young through a placenta, like in most mammals. Instead, embryos develop inside individual eggs until they hatch.
Do white sharks lay eggs?
Zebra sharks are oviparous meaning they lay eggs; in fact, females can lay up to 40 eggs at a time! As if this wasn't amazing enough, female zebra sharks can reproduce without the presence of a male, meaning their babies are technically clones of their mothers.
Do bull sharks lay eggs?
The great white shark is ovoviviparous, which means that the shark grows in an egg, which is then hatched inside the mother. Shortly thereafter, the shark pup is born. While in the womb, great white shark embryos feast on unfertilized eggs, a practice known as oophagy.
Does shark give birth?
They Give Birth to Live Young
Bull sharks are viviparous, which means that, unlike most sharks, they give birth to live young rather than laying eggs. Their mating season often occurs in late summer or early fall, and the developing pups are nourished in their mother's body by a yolk-sac placenta.
Do sharks ever sleep?
Shark pregnancy
Reproduction in sharks is equally varied: some lay eggs, but most give birth to live young. Sharks typically give birth after 11–12 months of pregnancy, but some, such as the frilled shark, are pregnant for more than three years. In some sharks, a placenta develops during pregnancy.
Do Megalodons lay eggs?
That depends on the shark species.
Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.
Do leopard sharks lay eggs?
Megalodon was a lamniform shark, like today's great white and mako sharks, as Smithsonian Magazine reports. Instead of simply laying eggs, as most fish do, lamniform shark eggs hatch inside the mother's body, and the young sharks remain there until they're large enough to survive on their own.
