The bull shark, Carcharhinus leucas, can swim between salt and fresh water, and are found in tropical rivers around the world. The river sharks (of the genus Glyphis ) can live in both saltwater and freshwater as well, while one of their members, the Ganges shark ( Glyphis gangeticus ), lives exclusively in freshwater.
Sharks are found in all seas. They generally do not live in fresh water, with a few exceptions such as the bull shark and the river shark which can swim both in seawater and freshwater. [99] Sharks are common down to depths of 2,000 metres (7,000 ft), and some live even deeper, but they are almost entirely absent below 3,000 metres (10,000 ft).
Young bull sharks leave the brackish water in which they are born and move out into the sea to breed. While is theoretically possible for bull sharks to live purely in fresh water, experiments conducted on bull sharks found that they died within four years. The stomach was opened and all that was found were two small, unidentifiable fishes.

Estuaries occur where there is a noticeable change in salinity between saltwater and freshwater sources. This is typically found where rivers meet the ocean or sea. The wildlife found within estuaries is unique as the water in these areas is brackish - a mix of freshwater flowing to the ocean and salty seawater. [20]
This species of shark often occupies the subtropical shallow waters of coral reefs, mangroves, enclosed bays, and river mouths; however, lemon sharks have also been found in the open ocean down to depths of 92 meters (301 feet.) [13] Although lemon sharks do swim up rivers, they never seem to travel very far into fresh water. They are found in ...
