Once the shark embryo is safely nestled inside its egg case, it's time for the waiting game. The length of the incubation period varies depending on the shark species, ranging from a few months to over a year. But don't worry, these little sharks aren't just sitting around twiddling their fins!
Shark pups: ready for the big blue world
When the time is right, the baby shark, also known as a pup, will hatch from its egg. But it's not as simple as breaking out of the eggshell and swimming away. Some shark pups have a special tooth or spike on their snout called an egg tooth, which helps them break free.

So, are sharks born in eggs?
