Gharial Definition

The gharial (Gavialis gangeticus) is a large, aquatic reptile and a species of crocodilian. Here’s a definition of the gharial:

Gharial General Characteristics & Facts


Gharials are found primarily in freshwater river systems, including the major rivers of northern India, Nepal, and Bangladesh. They prefer deep pools, sandbanks, and muddy shores for basking.


Gharials are specialized fish-eaters. Their slender snout is well-adapted for catching fish underwater. They mainly feed on small to medium-sized fish, but they can also consume crustaceans, frogs, and occasionally small mammals.

Breeding Behavior

During the breeding season, male gharials develop a bulbous growth on the tip of their snout, which acts as a resonating chamber for producing loud hissing calls. This vocalization is used to attract females. Gharials practice a unique nesting behavior known as “sandbank nesting.” Females dig large nests in sandy riverbanks and lay their eggs, which they guard until they hatch.

Endangered Status

Their population has significantly declined due to habitat loss, river pollution, depletion of fish populations, and accidental entanglement in fishing nets. It is estimated that fewer than 1,000 mature individuals remain in the wild.

Conservation Efforts

Several conservation programs are in place to protect the Gharial. Captive breeding programs have been initiated to increase their numbers, and reintroduction projects aim to release captive-bred individuals into suitable habitats. Protected areas and sanctuaries have also been established to safeguard their habitats.


Gharials are generally non-aggressive towards humans and prefer to avoid contact. They spend much of their time basking in the sun on sandbanks or submerged logs. They are well adapted to swimming and can remain submerged for long periods, using their eyes and nostrils positioned at the top of their head to remain mostly hidden underwater.


The lifespan of gharials in the wild is not well-documented. However, in captivity, they can live up to 40-60 years.

Special Adaptations

The slender snout of the gharial enables it to move swiftly through water with minimal drag. The long, sharp teeth are well-suited for catching fish. Their eyes and nostrils positioned at the top of the head allow them to remain mostly submerged while still observing their surroundings.

Cultural Significance:

Gharials hold cultural and religious significance in some parts of the Indian subcontinent. In Hindu mythology, they are associated with the river god Ganga. They are also considered a symbol of conservation and environmental awareness.

Physical Characteristics of Gharial

  1. Long, Thin Snout: The most notable physical feature of the gharial is its long and thin snout. The snout is elongated, slender, and specialized for capturing fish. It contains numerous sharp, interlocking teeth that are ideal for gripping and holding onto slippery prey.
  2. Ghara or Bulbous Growth: Adult male gharials develop a bulbous growth on the tip of their snout, known as the “ghara.” The ghara is thought to be a visual and vocal display organ used during courtship rituals and territorial displays. It gives the gharial a distinctive appearance.
  3. Slender Body: Gharials have a slender body shape that is well-suited for an aquatic lifestyle. Their body is streamlined, allowing them to move swiftly through the water with minimal resistance. They have long, muscular tail that propels them through the water while swimming.
  4. Size: Gharials are one of the largest crocodilian species. Adult males can reach lengths of about 15 to 20 feet (4.5 to 6 meters), while females are smaller, usually ranging from 10 to 14 feet (3 to 4 meters) in length. Males are significantly larger and heavier than females.
  5. Skin and Coloration: Gharials have rough, scaly skin that is dark olive or grayish-brown in color. Their skin is covered in armor-like plates called osteoderms, which provide protection. The coloration helps them blend in with their natural habitat.
  6. Webbed Feet: Gharials have webbed feet with claws, which assist in swimming and maneuvering through water. The webbing between their toes enables efficient propulsion while swimming, making them well-adapted to their aquatic lifestyle.
  7. Eyes and Nostrils: The eyes and nostrils of gharials are positioned on top of their long snout. This allows them to keep their eyes and nostrils above the water’s surface while the rest of their body remains submerged, enabling them to spot prey and breathe while partially submerged.
