How intriguing. These are all shark eggs. They are also called “Mermaid’s Purses”—tough leather-like capsules that protect the embryo and often have tendrils for clinging to seaweed or rocks. The horny shells of shark eggs are made up of roughly the same materials as our nails and hair. Their sizes vary from a few centimeters to about the size of a palm, and the development of the embryo takes months. After hatching, the empty capsules can be found on beaches. At the moment the egg emerges into the world, it has enough food supplies for the upcoming period. How they hatch: as soon as the right time comes, the shark egg slightly opens at the bottom, and the young shark slowly acclimates to the conditions in which it will live. After acclimation, it breaks through the egg’s shell and enters the open world.
