Crocodile Description

  • All crocodiles live in freshwater habitats such as lakes, wetlands, and rivers.
  • The crocodile’s body is adapted to swimming. It can tuck its feet to the side whilst swimming which allows the croc to swim faster.
  • The saltwater crocodile is the largest of the species while dwarf crocodile is the smallest.
  • The name of the longest crocodile ever lived is Lolong.
  • Crocs replace their 80 teeth up to as many as 50 times during their lifetime.
  • They are the close relatives of dinosaurs.
  • The crocodile’s eyes and ears are on top of its head. This allows the animal to hide while swimming.
  • They are mostly nocturnal animals.
  • Crocodiles have acute sense of smell.
  • A male crocodile died in Australian zoo at the age of 140 years.
  • The female croc lays eggs at night.
  • There are 14 living species of crocodile.
