Feature Facts

  • The name "gharial" comes from a Hindi word for a clay pot with a long neck, similar to the shape of an adult male gharial's (bulbous) snout
  • The male's bulbous snout alters vocalizations, making a buzzing rather than the hissing sound typical of crocodilians; may be important in courtship and/or communicating over longer distances
  • Once considered a conservation success, but efforts have "back slid" since the 1990s; only about 200 mature individuals remaining (as of 2017)
  • One of the largest crocodilians; can be as long/heavy as a saltwater crocodile
  • The only crocodilian which is sexual dimorphic, meaning some characteristics differ between females and males
  • Bulbous knob on male's nose is made of cartilage
  • Adapted for an aquatic lifestyle; has difficulty moving on land
  • Hatchlings stay close to their mother for protection; male allowed nearby—sometimes carries hatchlings on his back
