Crocodile, the killler of water

[Spalea]

" The theory of the evolution of species by natural selection.

To put it simply, it’s characteristic changes to a species due to a more efficient way it reacts and survives within its environment. Beneficial changes will help the individual survive and thus reproduce, passing on its successful characteristics.
The crocodile as we know it has been relatively the same for the past 200 million years, even outliving dinosaurs by some 65 million years. No need for characteristic changes when you’re that successful. Nature really succeeded with their design. "
