Dutch photographer Peter Verhoog recently captured a rare video at a Rotterdam zoo aquarium showing a spotted catshark baby moving in an egg sheath.
A translucent shark egg clings to aquatic grass in the water, and a spotted catshark baby sways in its egg sheath.
"Baby sharks have to be constantly moving to get oxygen," Peter said. "Shark eggs hatch after a few months." Oviparous sharks are known to lay eggs with thick egg sheaths that allow them to attach to rocks or seaweed. , the outer skin of the egg sheath hardens when it enters the water, making it resistant to predators.
