Shark egg - Yes, sharks do lay eggs. Some of them, anyway. About 70 percent of sharks are viviparous, meaning they give birth to live young; the remaining 30 percent of shark species — plus near-relatives like skates, rays and chimaeras (an order that includes the spooky "ghost shark") — are oviparous, meaning they lay eggs externally. Each shark egg contains an embryo (baby shark) and a yolk sac (baby's first meal), much like a chicken's egg. Look closely at the video, and you can even see the

Blacktip sharks (Carcharhinus limbatus) reproduce through a process called viviparity, in which embryos develop inside the mother and are nourished by a placenta-like connection. Mating typically occurs during the spring or summer, depending on the region, with males using their claspers to transfer sperm to females. After a gestation period of about 10-12 months, females give birth to a litter of 4-11 pups, although the number can vary. The pups are born fully developed and independent, measuri

A baby zebra shark (Stegostoma tigrinum) hatching from its eggshell 🐣Some sharks give birth to live young. Others, like the zebra shark, lay eggs. Female zebra sharks release these ‘leathery’ egg cases which they securely anchor to the seafloor. The egg cases are quite large - about 17cm in size - and contain everything the pup needs to develop and grow over the next 6 to 9 months before hatching. When the pups hatch, they are dark in color with white stripes (hence the common name “zebra shark

While the majority of sharks give birth to live young, chain catsharks are oviparous, meaning they lay eggs. The eggs are laid in protective cases called mermaid’s purses. The female shark in this video filmed in Ocean Wonders: Sharks! is shown “tying” the long curly tendrils of the egg cases to kelp to anchor them. This prevents the developing eggs from being swept away by tides or currents. Anchoring the egg cases is crucial to protecting them for the next eight to twelve months until they hat

While the majority of sharks give birth to live young, a number of species are oviparous, meaning they lay eggs. The eggs are laid in protective cases called mermaids’ purses. When sharks at the aquarium lay eggs, our keepers check on their development using a technique called candling, where they shine a bright light through the egg to monitor the embryo’s development. The egg cases shown in the video are chain catsharks and they were approximately four months into their eight and a half month
