Differences Between Crocodiles and Alligators

It can be difficult for inexperienced people to tell the difference between an American crocodile and the other native crocodilian, the more common American alligator.  The following are some of the major differences between the two:

Crocodiles

  • Grayish green color
  • Fourth tooth on lower jaw exposed when mouth is closed
  • Narrow tapered snout
  • Young are light with dark stripes

Alligator

  • Black in color
  • Only upper teeth exposed when mouth is closed
  • Broad rounded snout
  • Young are dark with yellow stripes
