A warm water species preferring temperatures of 26ºC or warmer. Found on inshore reefs and bays. It is a euryhaline species that travels thousands of kilometres up large rivers and into lakes that access the ocean. Surface to at least 152m
Remarks
Bull sharks mostly cruise close to substrate. They are known to travel over long distances, migrating into warmer water over the winter months. Bull sharks are well known for ability to tolerate fresh water. They have been found thousands of miles upriver but it is unclear if they are residents or nomadic in the world’s great tropical rivers
