- 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.

SHARK MIGRATION. One thing is for sure; sharks migrate to find new sources of food and they can travel up to hundreds of miles to do that. Most species of sharks live in the oceans. However, some of them are known to dwell in bodies of freshwater, like the bull shark which travels up to 4,000 Km up the Amazon River. Sometimes, sharks reach freshwater bodies; this could be the result of the destruction of their habitat by human activities.
