The main difference between saltwater and freshwater crocodiles is their size. Saltwater crocodiles are the largest members among all crocodiles while freshwater crocodiles are smaller. Also, the snout of the saltwater crocodiles is broader and thicker while the snout of freshwater crocodiles is longer and thinner. Moreover, the jawline of saltwater crocodiles is uneven while the jawline of freshwater crocodiles is even.
This is also a difference between saltwater and freshwater crocodiles. The teeth of saltwater crocodiles are unequal in size while the teeth of freshwater crocodiles are equal in size.
Saltwater crocodiles consume small reptiles, fish, turtles, wading bird, and larger prey like wild pigs, buffaloes, and livestock while freshwater crocodiles consume smaller animals like insects, fish, frogs, turtles, water birds, and snakes.
While saltwater crocodiles are more aggressive, freshwater crocodiles are less aggressive. This is another difference between saltwater and freshwater crocodiles.

In some parts of the world they have been almost hunted to extinction, due to the value of their hide, habitat clearing and their reputation as man-eaters. Feral buffalo destroy nesting habitats and goannas can dig out eggs from nests.
Hatchlings or juveniles can be eaten by barramundi, turtles, freshwater crocodiles and older saltwater crocodiles. Additional threats to the long term survival of the crocodile include habitat modification and encroaching human populations and the possibility of climate change induced sea level rises altering suitable habitats.
