One can easily tell the difference between these two animals by looking at their snouts.
While Crocodiles usually have long pointed snouts which is usually said to take a “V” shape in many descriptions, those of alligators are usually short, wider and takes a somewhat “U” shape.
Looking at the shape of their snouts one can easily tell that they are suited for their specific diet. For instance the alligators’ wide snout is suited for breaking turtle shells while the pointed snout of crocodile is suited for hunting.
Both the upper and lower teeth of crocodiles are usually pointed outwards and interlaced as opposed to what is present in the alligators that have only the upper teeth outward.
Recent studies showed that Alligators have shorter humerus bones in their forelimbs and shorter femurs in their hind limbs than crocodiles.
Alligators are only found in parts of the US and China, whereas crocodiles can be found across the world.
Alligators live only in the southeastern US and eastern China, whereas crocodiles can be found across the world in Africa, Australia, Southeast Asia, North America, South America, and Central America.
The populations of Alligators is more than that of crocodiles in the US. There are over 3 million alligators, but fewer than 2,000 crocodiles.
Southern Florida is the only place in the world where you will find crocodiles and alligators living side by side.
