  • Some crocodilians 1 bait birds by putting nest-worthy twigs on their snouts. When a bird flies down to pick up the twigs, the crocodilian lunges up and eats it.
  • Crocodilians use gastroliths for digestion and maybe also for buoyancy and balance.

O.crocodilia contains three families: f.gavialidae, the gharials and false gharials; f.alligatoridae, the alligators and caimans; and f.crocodylidae, the crocodiles.
