The bull shark is most often found at depths of less than 150 meters. However, it is not impossible to find this fish at other depths.
The bull shark evolves near coastlines. It is adapted to changes in salinity and is known for its excursions in rivers. A specimen was caught in Peru, over 3,000 km from the coast. It is a regular resident of estuaries and coastal coves. It seems to appreciate waters with high turbidity.
