Gharials (Gavialis gangeticus) are massive crocodilians with long, slender snouts equipped with sharp teeth ideally suited for capturing
fish in deepwater portions of riverine systems on the Indian Subcontinent.

The Gharial (Gavialis gangeticus) is a massive crocodilian,
exceeded in size only by the Saltwater Crocodile (Crocodylus

porosus). Historically, male Gharials of up to 6 m (nearly 20 ft)
were commonly encountered, but such large individuals are
unknown today. The species is characterized by its elongated,
narrow snout, which varies in shape as an animal ages, becom-
ing proportionally shorter and thicker over time. The bulbous
growth on the tip of a male’s snout, called “ghara” after the
Indian word meaning “pot,” is present in mature individuals,
which utilize the structure to to modify and amplify “hisses”
snorted through the underlying nostrils. The resultant sound can
be heard for nearly a kilometer on a still day. The ghara also ren-
ders Gharials the only visibly sexually dimorphic crocodilian.

The well-developed laterally flattened tail and webbed rear
feet provide tremendous maneuverability in the Gharials’ deep-
water habitat, where their diet consists primarily of fish. On
land, however, an adult Gharial can do little more than push
itself forward and slide on its belly, and it will leave the water
only to bask or to nest on sandy beaches. Males will guard a ter-
ritory in which several females live. Mating usually occurs dur-
ing December and January and nesting from March to May,

which corresponds to the dry, low water season. Females will
excavate an egg chamber in the sandy banks above the flood line,
depositing up to 60 eggs and carefully covering them. The eggs
are the largest of any crocodilian species, weighing an average of
160 g. Eggs hatch after 83–94 days. Female Gharials dig up the
young in response to hatching chirps, but, unlike many other
crocodilians, do not assist the hatchlings to the water. They will,
however, guard the hatchlings for some time. Although this
remarkably gentle animal once thrived in the deep rivers of
India, Nepal, Pakistan, Bangladesh, Bhutan, and Myanmar, it is
now virtually extinct in all but the first two of these countries,
where it is limited to 2% of its former range.

Gharials were once distributed across approximately 20,000 km2 of riverine habitat of the Indus, Ganges, Brahmaputra, and Irrawady river sys-
tems. Today populations are limited to a few refuges: (1) National Chambal Sanctuary; (2) Katerniaghat Sanctuary; (3) Chitawan National Park;
(4) Son River Sanctuary; (5) Satkosia Gorge Sanctuary. No breeding is occurring in the Satkosia Gorge Sanctuary. Scattered individuals are known
to occur along other rivers in India and Nepal, but no reproduction has been documented in decades. Solid crosses indicate that populations are
presumed to be extirpated, and outlined crosses mark populations that are extirpated.

Early Records
Early records for the Gharial are mainly anecdotal. Old refer-
ences indicate the Gharial’s abundance: common in the Indus
River in Pakistan (Francis 1910, Rao 1933); Gandak River in
Nepal (I.A.K. 1921); Jumuna River in Uttar Pradesh (Hornaday
1885), and Kosi River in Bihar (Shortt 1921). Several authors
mentioned seeing groups basking together. In 1885, Hornaday
wrote that he had counted 64 Gharial in two hours on the banks
of the Jamuna. Adams (1867) wrote: the Gharial “abounds in all
the great rivers of Northern India … Ten or twenty may be fre-
quently seen together. Hundreds of Gharial were observed on
the Narayani River (Nepal) prior to the construction of the
Gandak barrage … in 1964 and in the early 1950s about 235
Gharial were counted along the Narayani River between
Narayanghat and Tribeni” (Maskey 1999). With a historic range
of thousands of river kilometers of habitat over an area of about
20,000 km2, from the Indus to the Irrawady, the Gharial had an
inferred population of 5,000 to ≥ 10,000.

Current Status
By 1976, the estimated total population of wild Gharials had
declined from an inferred 5,000–10,000 animals in the 1940s
and throughout its huge former range (spanning the rivers of the
northern part of the Indian Subcontinent from the Indus in
present-day Pakistan 3000 km eastward across the Gangetic
floodplain to the Irrawady in Myanmar) to fewer than 200
(Whitaker 1974), a decline of about 96%.

The Indian government subsequently accorded protection
to the Gharial under the Wildlife Protection Act (WPA) of
1972. Project Crocodile began in 1975 under the auspices of the
Government of India with the aid of the United Nations
Development Fund (UNDP) and Food and Agriculture
Organization (FAO). The project included an intensive captive-
breeding and rearing program intended to restock habitats with
low numbers of Gharials. An acute shortage of Gharial eggs was
overcome by their purchase from Nepal. A male Gharial was
flown in from the zoo in Frankfurt, Germany, to become one of
the founding animals of the breeding program.

Sixteen crocodile rehabilitation centers and five crocodile
sanctuaries (National Chambal Sanctuary (NCS), Katerniaghat
Wildlife Sanctuary (KWS), Satkosia Gorge Wildlife Sanctuary,
Son Gharial Sanctuary, and Ken Gharial Sanctuary) were estab-
lished in India between 1975 and 1982. By 2004, 12,000
Gharial eggs had been collected from wild and captive-breeding
nests, and over 5,000 Gharials reared to about a meter or more
in length (roughly three years of age) and released into the wild.
Over 3,500 of these were released in NCS, the largest Gharial
reserve in the country, sprawling across 425 km2 in the states of
Uttar Pradesh, Madhya Pradesh, and Rajasthan.

In 1982, a report by a wildlife biologist for the
FAO/UNDP listed Project Crocodile among the most success-
ful conservation projects in the world. However, in 1991, the
Union Ministry of Environment and Forests felt that the proj-
ect had served its purpose, and stopped funds for its captive-
breeding program. Funds were also withdrawn for the egg-col-
lection program. The thousands of crocodiles seen in various
rearing stations and captive breeding centers clearly attested to
the success of the project. However, little had been done to

Many large males were killed by hunters from Nepal or Europe well
into the 20th Century. This hunt was in what was to become the Royal
Chitwan National Park and occurred just before the protected area was
created. Today, only four large, mature males like that in the photo-
graph remain in the Narayani and Rapti rivers around the park.

involve the local communities in conservation, and that has been
the key failure in securing the future of the species in nature. In
1997–1998, monitoring exercises by the forest departments of
Madhya Pradesh, Rajasthan, and Uttar Pradesh located over
1,200 gharials and over 75 nests in NCS — but no surveys
occurred between 1999 and 2003.

By 2006, the inferred mature gharial population in India
had plummeted to fewer than 200 adult individuals (Andrews
2006, Sharma and Basu 2004) and fewer than 35 adults in
Nepal (Maskey 2006). The species is virtually extinct in Pakistan
(Whitaker and Basu 1983), Bangladesh (Whitaker 1976, Khan
1979, Faizuddin 1983), and Bhutan (Singh 1991). Only two
records for the species were recorded from Myanmar in 1927,
and it is presumed to be extinct in that nation.

Reasons for Decline
The drastic decline in the Gharial population over the last 60
years (three Gharial generations) can be attributed to over-hunt-
ing for skins and trophies, egg-collection for consumption, killing
for indigenous medicine, and killing by fishermen. In addition,
dams, barrages, irrigation canals, siltation, changes in river course,
artificial embankments, sand-mining, riparian agriculture, and
land-use changes to accommodate domestic and feral livestock
have combined to limit the range of Gharials as a consequence
of excessive, irreversible loss of riverine habitat. These threats have
not ceased, indeed have increased and continue to compromise
the survival of the species. The misguided megaplan to interlink
the major Indian rivers will be the final nail in the coffin. Gharial
declines have gone hand-in-hand with declines of other riverine
taxa once reportedly abundant and now endangered. These
include the Ganges River Dolphin (Platanista gangetica),
Smooth-coated Otter (Lutrogale perspicillata), and the Mugger

Gharials, such as this adult female, are powerful swimmers but grace-
less on land. The laterally compressed tail serves both to propel the ani-
mal and as a base from which to strike at prey.

fowl and well-known game and edible fish species such as the

Mahseer (Tor sp.) and Hilsa (Hilsa illisha). GMTF is collaborat-
ing with WWF-India to form “Riverwatch,” which will monitor
all of these endangered river taxa.

Nest Counts
The mature Gharial population was estimated by using nest
counts, as they are easily visible and counted at well-known loca-
tions that have been monitored for decades. This is likely to be an
accurate assessment for numbers of mature animals, because of the
unknown number of immature males that are routinely counted
as “adults,” before they grow a ghara at 12–15 years of age.
Females reach sexual maturity when they are around seven years
old and about 2.4–2.7 m in total length. Males do not mature
until they are about 4 m in length at 15–18 years of age. Using
the only published data on ratios of males in the mature Gharial
population (14%) (Hussain 1999), we inferred that a proportion
of all ‘adults’ reported in censuses are actually subadult males.

Fishermen, who illegally set nets in the National Chambal Sanctuary, will cut off Gharials’ snouts, leaving them to starve.

Breeding Populations
The Chambal River supports the largest breeding subpopulation
and is the largest remaining Protected Area for Gharials, with an
estimated 48% of the total population. The total number of
nests found in the National Chambal Sanctuary in 2006 was 68.
The other large breeding population of Gharials in India is in
the Katerniaghat Wildlife Sanctuary (KWS), where 20 nests
were found in 2006. The only other known breeding popula-
tion in India is the Son River Sanctuary, where two nests were
found in 2006 (for the first time in 30 years; Andrews 2006).

Since many female Gharials nest every year in captivity, the
assumption that the above-cited nest counts indicate the pres-
ence of 90 reproducing female Gharial in India is reasonable.
Consequently, the reported paucity of mature males (with their
very conspicuous gharas) on the Chambal in the surveys of 2005
and 2006 and the resulting drastically low estimate of mature

males are likely to be accurate for that river (Andrews 2006, Rao,
pers. comm.). However, a total of 20 nesting females and six
mature males were counted in the KWS by independent
observers in 2006 (B.C. Choudhury, H.V. Andrews, R.
Whitaker, pers. obs.). The total inferred number of mature
Gharials in the three remaining wild breeding subpopulations
in India is therefore 107, based on observed nest numbers and
inferred numbers of mature males.

Other Subpopulations
Two other small, non-reproducing populations of Gharials are
known to exist in India (Ken River in Madhya Pradesh and
Mahanadi River in Orissa). These have been supplemented by
the reintroduction of captive-bred stock (as in all present Gharial
locations). A few scattered Gharials may also remain in the
Brahmaputra River of northeastern India, but confirmed sight-
ings date to 1993 (Choudhury 1997). These other subpopula-
tions in India contain a total estimated 40 mature animals (no
mature males nor any breeding have been reported). The
Gharial is undoubtedly extinct in the Indus (Pakistan/India) and
Irrawady (Myanmar) river systems.

Gharial declines have gone hand-in-hand with declines of other riverine taxa, such as the Ganges River Dolphin (Platanista gangetica; above) and
the Mugger Crocodile (Crocodylus palustris; top right). The latter was photographed at the Katerniaghat Sanctuary along one of the Ganges River
tributaries.

U.S. Efforts to Aid Gharial Conservation

Although the critical work to protect Gharials from
extinction in the wild is most needed in their native
habitat, zoos in the United States support these efforts
wherever possible. In 2004, the Cleveland Zoo and
the San Diego Zoo started a fund to help support in-
situ conservation. Since then, the two zoos have con-
tributed $26,000 to the Gharial Multi-Task Force
(GMTF). These funds are used for Gharial surveys,
ongoing monitoring of known populations, and oper-
ational expenditures by the local associates of the
GMTF. Although they do not keep Gharials, the
Dallas Zoo recognized the precarious position of the
wild population and recently joined in contributing
to the fund. A plea has been extended to other AZA
institutions to contribute to this important endeavor.

Another objective is to create a self-sustaining
population to serve as a genetic reservoir for the
species. To accomplish this, the current U.S. popula-
tion of 21 animals would have to be supplemented by
captive-reared animals from India. Although no
Gharials have been born in captivity in the United
States (possibly due to the fact that the potential
breeders have yet to reach sexual maturity), over 4,500
animals have been raised in captivity and returned to
the wild in India, proving that a self-sustaining cap-
tive population is attainable.

A self-sustaining population of Gharials in the
United States would have the additional benefit of
increasing the number of institutions that keep these
alluring animals. This would help to raise awareness
and funds for Gharial conservation and create a
broader base of support for pressuring the Indian and
other governments to act decisively to protect Gharials
in the wild.

Also, the actions of some conservation organiza-
tions that focus on species other than Gharials have
contributed to their conservation. One example is the
Turtle Survival Alliance. This coalition of zoos, insti-
tutions, and individuals with divisions in the United
States, Europe, and Austral-Asia, supports the protec-
tion of critical habitat for turtles such as the Red-
crowned Roofed Turtle (Kachuga kachuga), which is
sympatric with Gharials in part of their range. Asian
turtles and Gharials both are faced with the threats of
habitat destruction, poaching, and high mortality due
to illegal fish-netting practices. While the alliance
focuses on turtles, other endangered species, such as
Gharials and the Indus River Dolphin, benefit from
efforts to protect habitat and enforce laws that protect
wildlife.

Gharials in Nepal
Six nests were counted in 2006 in Nepal in Chitawan National
Park (Rapti/Narayani River) and three other small, non-reproduc-
ing subpopulations are known (Kosi, Karnali, and Babai rivers).
The total number of mature Gharials in all subpopulations in
Nepal is inferred to be 35 animals (Maskey 1999, pers. comm.).

How Many Gharials?
Unless additional research tells us otherwise, we have to assume that
the maximum number of wild, mature Gharials across the entire
remaining range of the species (presently only India and Nepal) is
182 in about eight non-contiguous, fragmented habitats.

Gharial Declines in the Past Decade
In 1997, the peak year with the highest numbers of wild mature
Gharials and nests recorded in the last 30 years, 226 mature ani-
mals and 81 nests were recorded in the Chambal (Sharma and
Basu 2004). Although no nests were found in the Son, about 10
mature individuals occurred there. We had no nest data for
Katerniaghat, where an estimated 30 mature animals were pres-
ent. No nesting data from Nepal exist for this period, with an
estimated 36 mature Gharials reported (Maskey 1999).

Based on the available data (Sharma and Basu 2004,
Maskey 1999) and adding the 2006 estimated numbers of non-
breeding mature animals (in small subpopulations outside the
three Indian and one Nepali breeding subpopulations — a total
of 40 animals), the estimated total mature Gharial population
throughout its present range (India and Nepal) in 1997 was 342.

The decline from an estimated 342 adult Gharials in 1997
to 182 in 2006 represents a 47% decline across the species’
range. This drastic decline occurred within a period of nine
years, well within the span of one generation, qualifying the
Gharial, under criterion C1 of the IUCN Red List, to be listed
as Critically Endangered, although the current status is listed as
endangered (Crocodile Specialist Group 1996).

Present Distribution of the Gharial
The total extent of occurrence of the Gharial was once on the
order of about 20,000 km2 (including suitable areas of the
Indus, Ganges, Brahmaputra, and Irrawady river systems). Rao
and Singh (1995) reported a figure of 2,986 km2 (in India). In
Nepal, the total area of occupancy is now under 100 km2,
whereas it once could have been close to 1,000 km2 (Maskey,
pers. comm.). Current total area occupied in India and Nepal is
less than 250 km2, based on river length x width and occurrence
of Gharials within Protected Areas.

Summary of Gharial Restocking Programs
One perspective suggests that little has been accomplished other
than throwing over 5,000 juvenile Gharials into largely inhos-
pitable habitats in Indian and Nepali rivers and leaving them to
their fate. Little was done to secure the habitat. Banned from
fishing in sanctuaries created for Gharials, local communities
were not offered alternative employment. Combined with the
lack of enforcement, Gharials are at the mercy of embittered and
disempowered local people.

In Chitawan National Park (Nepal), where 457 Gharials
were released, 16 nests were counted in 1977 and only six in
2006. Reintroduction was not successful there (although one
argument states that at least total extinction was averted by sup-
plementation). The principal reasons for failure was growing and
uncontrolled anthropogenic pressures, including the depletion
of fish resources.

In the Girwa River (Katerniaghat Sanctuary), where 909
Gharials were released (including 112 in 2006), four nests were
recorded in 1977 and 20 in 2006, so 16 nesting females (2% of
the total pre-2006 releases) comprised the result of 30 years of
reintroductions. This seemingly poor achievement, considering
the money and effort spent, suggests that enforcement is the key
to Gharial survival (although some argue that the carrying
capacity may have been reached).

In the third and most important remaining Gharial breed-
ing habitat, the Chambal River (the tri-state National Chambal
Sanctuary), where 3,552 Gharials were released (Whitaker and
Andrews 2003) (plus 224 in 2006), 12 nests were recorded in
1978 and 68 in 2006. While nesting has apparently increased
by over 500%, these recruited mature, reproducing females rep-
resent only about 2% of the total number released. The linear,
riverine habitat of the Gharial presents a potentially insurmount-
able challenge with annual monsoonal flooding, when the newly
hatched young are especially prone to being flushed downstream
and out of the Protected Areas.

IGUANA  •  VOLUME 14, NUMBER 1  •  MARCH 2007 33GHARIAL

With recruitment or retention of reintroduced Gharials
(plus natural recruitment) over the last 30 years as low as 0.02%
(Mahanadi River, Orissa) and averaging 3–10% elsewhere, the
entire reintroduction strategy needs to reassessed. Scarce conser-
vation funds and human resources need to be focused on habi-
tat assessments, studies of Gharial ‘migration,’ fisheries assess-
ment/enhancement, and conflict mitigation. The latter, basically
recruiting support of the river people, may be particularly criti-
cal if we are to improve the survival odds of Gharial in their few
remaining refuges. However, the four sites where Gharials are
still breeding all had residual populations when the restocking
programs began. Nowhere has restocking re-established a viable
Gharial population.

The Situation is Not Futile

Follow these three “-fuses” to help save the Gharial:
Infuse yourself with more information. Learn more about
Gharials (www.nationalzoo.si.edu, www.flmnh.ufl.edu/
cnhc/csp_ggan.htm, www.ircf.org,  www.gavialis.org). To
stay current, sign up to receive updates from the Gharial
Multi-Task Force through IRCF. Diffuse what you learn
to your friends. A colleague recently saw a Gharial while
touring India, but had no idea they were so close to
extinction. Make sure everyone you know realizes that we
are close to losing the few Gharials remaining in the wild.
Effuse cash to funds that support Gharial conservation.
The IRCF website allows you to donate online with
100% of the funds going directly to the Gharial Multi-
Task Force. You also can support other conservation
funds that protect Asian turtles, Indus River Dolphins,
and even tigers, because all of them need the same ripar-
ian habitat as Gharials.
