It is thought that most primitive animals evolved to live in the sea. Indeed the composition of the clear part of Human blood is very much like sea water. The problem comes not for animals that live in the sea but when life spread from there to fresh water and then land.
In other words, the osmotic potential of the cells and bodies of marine animals is perfectly balanced with the osmotic potential of seawater. It is only when animals moved to freshwater and land that systems and energy needed to be expended to maintain the original seawater like osmotic potential of the cells and bodies of these animals against the osmotic potential of fresh water or indeed an arid external environment.
