The river sharks are six (two to be formally described) rare species of shark in the genus Glyphis, although, due to their secretive habits, other species could easily remain undiscovered. The river sharks are members of the family Carcharhinidae, and thus share the basic characteristics of the group. The bull shark is sometimes called both the river shark and the Ganges shark; it should not be confused with the true river sharks of Glyphis.
