  • You can describe crocodile as a swift swimmer because of its streamlined body. They stuck their feet inside the water to increase their swimming speed.

  • They are capable of living underwater because of a palatal flap at the back of their mouth. It is a layer of hard tissues stopping the entry of water inside their nose and mouth. Their nostrils close when they are underwater. They can hold their breath underwater for up to 1 hour.
  • They have scaly skin on their back known as osteoderms. Their sides and bellies are smooth.
  • There are dwarf crocodiles with a size of 4.9 to 6.2 feet (1.5 to 1.9 m) while their largest species are saltwater crocodiles reaching 23 feet (7 m) and weighing up to 1000 kg.
  • It is correct to describe crocodile as polyphyodonts which mean their teeth keep on being replaced. Having a set of 80 teeth, they replace them about 50 times in their lifespan of 35 years to 75 years. (See What’s Bigger Crocodile Or Alligator?)
  • Having the strongest bite among the kingdom Animalia still doesn’t help them in eating. It is because their jaw muscles cannot move so they are unable to chew their prey. Therefore, they hold their prey and roll with it to break it into pieces for easy swallowing. It is not because they pity their prey rather their eyes water because of excess hissing, rolling, and huffing while eating. 
  • Over a lifetime, crocodiles can have almost 4000 teeth because each tooth is replaced 50 times. Their jaw power or bite is the world’s strongest animal bite. They can apply 5000 pounds of pressure per square inch when they bite. However, the muscles for opening their jaw are not that strong and can be shut easily.
  • They use their voice to communicate with each other. Young ones squeak and grunt while adults can hiss, growl and roar. They respond to the voices of engines, gunshots, and humans mimicking them. Their sleeping style is quite different because they sometimes sleep with one eye open.
  • There are cases when they have eaten their younger ones. They are capable of hunting down an elephant, hippo, and other large mammals. Their digestive system is the most acidic, helping them digest these animals. 
  • Crocodiles often swallow small stones to help digestion as they swallow big pieces or even whole prey without chewing. They are nocturnal with excellent night vision and a great sense of smell. (See Do Sheep Sleep?)
