Gharial (Gavialis gangeticus) Fact Sheet: Diet & Feeding

Gharial (Gavialis gangeticus)

Diet

  • Primarily a fish eater; also aquatic frogs.
  • Uncommon reports of other food items: soft shell turtles, birds, plant material, small mammals.
  • Young eat tadpoles and invertebrates, in addition to fish.

Feeding

Strategies

  • Sit and wait: anterior of body floating or completely submerged; remains motionless waiting for prey.
  • Sweeping search: head and front of body slowly sweeps through the water back and forth looking for prey. Detection facilitated by presence of ISO's 
  • Rapid strike: suddenly, swings snout to the side and grabs a fish in one swift motion. The narrow snout reduces drag in the water, allowing for a quick, whip-like motion.
  • Gastroliths: occasionally swallow small stones (=gastroliths) to assist in grinding up food.
