Did you know?
- Many shark eggs have a leathery, rectangular shape with long thread-like appendages at the corners. These appendages help to attach the egg to seaweed or other underwater structures.
- Some shark species, such as the Port Jackson Bullhead Shark, lay spiral-shaped eggs that look like large screws. This structure helps the eggs to anchor themselves firmly in crevices or between corals so that they are not washed away.
- Some shark egg capsules are so transparent that you can see the embryos inside. In some species, you can even see the little baby shark moving, breathing and even practicing hunting moves before it hatches!
