Mega Meg Babies

“Baltimore: National Aquarium – Megalodon Jaws” by wallyg

           Megalodons as we all know are terrifyingly huge sharks. What we haven’t considered is the size of their babies. Their babies are over 2m long, larger than most adult humans. This is due to Meg’s eggs hatching inside the womb, where the babies grow bigger and hungrier before their mothers ever give birth. But not all embryos survive the gestation process: Some are eaten by their womb-mates. 

           They figured this out by examining the spine of the now extinct megalodon. Sharks deposit rings of hard tissue on their vertebra each year, and like the trunk of a tree these can be used to estimate age. Looking down through the layers, the team could see how large this vertebra was when the shark was born. 

            Before they were born, it is said that they ate their siblings. The hatched embryos begin to eat the surrounding eggs and in some cases, like the sand tiger shark, they eat other embryos too. It is likely at least two megalodons were born at a time.
