The big khauna
lol yes true but how much of the ocean have we actually explored it could be possible its still lied deep in the ocean i mean we are still trying to invent a sub that wont implode due to the pressure so we really only covered the surface of the ocean not the deep
The fact that our current craft cannot withstand the pressures of the deep ocean should tell you how difficult it is for
life to do the same. Furthermore, life in the abyss is very much different from life in the upper oceans, almost alien to what we know. Even
if the ancient shark could have at some point made its home there, it'd have to evolve significantly in order to adapt to its environment, rendering the whole argument moot as it would no longer be classifiable as the megalodon.
