Snout Shape

Alligators feature wide, U-shaped snouts, while crocodiles possess long, V-shaped ones, defining their distinct facial structures and aiding in habitat-specific feeding behaviors.


Alligators favor freshwater habitats, whereas crocodiles exhibit adaptability to both freshwater and saltwater environments, allowing for broader habitat colonization.

Geographic Distribution

Alligators primarily inhabit the United States and China, while crocodiles boast a global distribution across various continents, showcasing their ecological versatility.

Tooth Visibility

Alligators conceal their upper teeth when their jaws are closed, unlike crocodiles whose upper and lower teeth are prominently visible, distinguishing their dental anatomy.


Alligators tend to display less aggression towards humans compared to crocodiles, making encounters with the former less hazardous in certain situations.
