Organisms such as fish, living in water, need oxygen to breathe for cells to sustain. The available evidence suggests that gills were present in the very earliest fish. If the blood flow of fish was going in the opposite direction and flowed parallel to the movement of the water, the oxygen for carbon dioxide exchange would have been much less significant and fish would not have been able to breathe. Do fish have lungs? But are there any types of actual fish that do have lungs? That's a great question.
