It was found that the bull shark stayed at the mouth of the river independent of the salinity of the water. The driving factor for a bull shark to be in freshwater or saltwater is its age; as the bull shark ages the tolerance for very low or high salinity increases.ne way the bull shark is able to conserve energy is that when the tidal flow changes, the bull shark uses the tidal flow in order to conserve energy as it moves downriver. Another way for the bull shark to conserve energy is to decrease the amount of energy needed to osmoregulate the surrounding environment.
