The '''Ganges shark''' ('''''Glyphis gangeticus''''') is a [[critically endangered]] species of [[requiem shark]] found in the [[Ganges River]] ([[Padma River]]) and the [[Brahmaputra River]] of [[India]] and [[Bangladesh]]. It is often confused with the more common [[bull shark]] (''Carcharhinus leucas''), which also inhabits the Ganges River and is sometimes incorrectly referred to as the Ganges shark.<ref name=Compagno1997>{{cite journal |last=Compagno |first=L.

The species remains poorly known and very rare.
