The most easily noticed difference between the species (besides size) is the shape of the head and teeth.
Freshwater crocodiles have longer and thinner snouts, with a straight jawline, and all their teeth nearly equal in size.
Saltwater crocodiles have a broad, powerful-looking snout, with an uneven jawline. Their teeth vary in size with some almost twice the size of others.
