Alligator vs Crocodile: What’s the Difference?

At first glance, alligators and crocodiles look almost identical—both are large, scaly reptiles with powerful jaws. But these ancient predators have key differences in appearance, behavior, and habitat. Whether you're a wildlife enthusiast or just curious, here’s how to tell them apart!

1. Snout Shape: U-Shaped vs. V-Shaped

Alligator: Broad, U-shaped snout (better for crushing prey like turtles).
Crocodile: Narrow, V-shaped snout (ideal for catching fish and mammals).

2. Teeth Visibility: Hidden vs. Exposed

Alligator: Only upper teeth show when the mouth is closed.
Crocodile: Both upper and lower teeth interlock, creating a toothy grin.

3. Habitat: Freshwater vs. Saltwater

Alligator: Prefers freshwater (swamps, lakes, rivers). Found in the U.S. (Florida, Louisiana) and China.
Crocodile: Tolerates saltwater (estuaries, coastal areas). Found in Africa, Australia, and the Americas.

4. Skin Color: Dark vs. Olive/Brown

Alligator: Dark black or gray.
Crocodile: Lighter, olive or tan with more visible patterning.

5. Temperament: Shy vs. Aggressive

Alligator: Generally avoids humans (but still dangerous!).
Crocodile: More territorial and likely to attack unprovoked.

6. Size: Who’s Bigger?

Alligator: Max length ~14 ft (American alligator).
Crocodile: Saltwater crocs can exceed 20 ft (the largest reptile on Earth!).

7. Speed: Surprisingly Fast!

Both can sprint short distances (~11 mph), but crocodiles are more agile in water.

Bonus: Which Is More Dangerous?

Crocodiles are responsible for more fatal attacks due to their aggressive nature. Alligators usually flee unless provoked.

Final Verdict: While they share a prehistoric ancestry, alligators and crocodiles differ in snout shape, teeth, habitat, and behavior. Next time you see one, check the snout—it’s the easiest way to tell them apart!
