Scientific name.........Glyphis Gangeticus
Common name........Ganges river shark
The Ganges shark is a large stocky shark, without conspicuous
markings. Broadly rounded short snout and small dark eyes. The first
dorsal fin is over the last third of the pectoral fins, with a free
rear tip that is well in front of the pelvic fins. The second dorsal
fin is much smaller than the first, but is still relatively large.
The anal fin is slightly smaller than the second dorsal fin. The
pectoral fins are broad and falcate. A longitudinal upper precaudal
pit is present, but the interdorsal ridge is absent.
The maximum size of the Ganges sharks is approximately 6.7 feet and
The upper teeth of the Ganges shark have high, broad, serrated
triangular cusps, first few lower front teeth with weakly serrated
cutting edges and low cusp lets in crown foot, which protrude
prominently when mouth is closed.
These sharks tend to have a uniform gray to brownish coloration,
without any conspicuous markings or pattern with white underneath.
Its feeding habits are unknown, but is suggested because of their slender
teeth that they are primarily fish-eaters adapted to life in turbid
The Ganges shark, as its name suggests, is largely restricted to the
rivers of the Indo-Western Pacific, particularly the Hooghly River
of West Bengal, India. Individuals have also been sighted in waters
in the vicinity of Karachi, Pakistan. It is known to inhabit only
freshwater, inshore marine and estuarine systems.
Probably viviparous, measuring 23 inches at birth.
This species is potentially dangerous, though its reputation as a
man-eater is still unproven. There are much more dangerous sharks in
the Ganges such as the Bull shark; it represents a greater definite
danger threat than this threatened and elusive species.
The Ganges shark is believed to be critically endangered.
There are six known river sharks, ( Ganges shark, Speartooth shark,
Bizant river shark, Borneo river shark, and the New Guinea river
shark ), that are definitely rare and probably endangered.
Collectively, their distribution, life history, and ecology is a
virtual cipher. So, very little is known about these mysterious
creatures. Perhaps the most familiar is the Ganges shark, which has
a reputation as a man-eater in India. Its ferocious reputation may
not be warranted, however, due to confusion with the Bull Shark,
which also occurs in India's Bombay, Cochin, and Hooghly rivers.
