The Ganges shark (Glyphis gangeticus) is a rare species of fresh water shark that dwells in the Ganges River. It should not be confused with the Bull shark, which also inhabits the Ganges River and is sometimes referred to as the Ganges shark. It is stocky, with a broadly rounded snout and small eyes. The shark tends to have a uniform gray to brownish coloration, with no discernible pattern or markings.
A freshwater species, the notorious Ganges shark is known from only two surviving specimens collected in the Ganges River. Its small eyes may indicate that this species lives exclusively in the murky Ganges.
The Ganges shark, as its name suggests, is largely restricted to the rivers of Eastern and North-Eastern India, particularly the Hooghly River of West Bengal.The Ganges, Brahmaputra, Mahanadi in Assam, Bihar and Orissa respectively. Bengalis call it Baagh Maach which means tiger fish. It is typically found in the mid to lower reaches of a river.
