7 Key Differences Between Alligators and Crocodiles

Key Differences Between Alligators and Crocodiles

Alligators and crocodiles are different in themselves as they have different sizes, colors, and shapes of their snout. That’s why these two species can’t come under one category.

There are many ways from which anyone can easily identify a crocodile and alligator. Below is the list of differences between alligator and crocodile traits that can point out their uniqueness clearly:

  1. Location
  2. Eating habits
  3. Appearance
  4. Lifespan
  5. Coloring
  6. Skin Texture
  7. Predators

Once you understand the differences well, you can easily identify between these two reptiles. Let’s explore each difference in detail for a better understanding.

Alligator vs Crocodile : Location

Alligator vs Crocodile : Location

The first difference is the location. You have to know where alligators and crocodiles live.

Both have different and unique ranges and habitats that they prefer to live in. why? Crocodiles have special glands in their tongues that help them excrete excess salt from their bodies. So they can easily live in salt waters.

On the other hand, alligators don’t work this way; that’s why they usually stick to freshwater habitats.

Here are the locations of both reptiles:


  • Southern United States (American alligator)
  • China (Chinese alligator)


  • South Florida (crocodile)
  • South America
  • Asia
  • Central America (American crocodile)
  • Egypt and 25 other countries in Africa (Nile crocodile)
  • Oceana

Do you know that there are more alligators in America than crocodiles? Yes, you’ll be surprised to know that over 3 million alligators but only less than 2,000 crocodiles are present in the US.

If you want to see both reptiles living in the same place, you must visit Florida! That’s the only place where crocodiles and alligators live side by side.

Alligator vs Crocodile : Eating Habits

Do Alligators and Crocodiles eat the same food?

Both reptiles usually eat fish, birds, turtles, and various mammals. Alligators and crocodiles are apex predators; that’s why they only consume those animals for their source of nutrition.

Here is a list of animals on which these two capable hunters can prey:


  • Fish
  • Frogs
  • Turtles
  • Birds
  • Sharks
  • Worms
  • Bobcats
  • Wild Boars
  • Deer
  • Rays
  • Snakes
  • Tadpoles
  • Spiders
  • Florida panthers
  • Black bears


  • Carrion
  • Flamingos
  • Tilapia
  • Goats
  • Domestic dogs
  • Frogs
  • Bass
  • Wildebeest
  • Possums
  • Storks
  • Cattle
  • Sharks
  • Crabs
  • Sea Turtles

You can see that both reptiles have different diets. As compared to the alligator, the crocodile has more potential prey. That’s because crocodiles live in and around saltwater.

Another interesting thing about alligators and crocodiles is that they also eat fruits apart from animals.

Alligator vs Crocodile: Physical Appearance

Alligator vs Crocodile: Physical Appearance

If you know the difference, you can easily tell the difference between alligator and crocodile, even from a distance. Look at the shape of the snout and the visibility of the teeth.

Crocodiles have longer and more pointed “V”-shaped noses, whereas alligators have a wide “U”-shaped, a rounded snout that looks like a shovel.

Apart from the snout, they also have different jaw shapes and teeth. You can notice this when their mouths are closed. The upper jaw of an alligator is wider than the lower jaw, and that’s why you can’t see its teeth at all.

On the other hand, you can easily see the crocodile’s bottom teeth even when its jaw is closed. Apart from their grin smile, the fourth tooth on each side of the lower jaw always sticks up over the upper lip.

As compared to alligators, crocodiles live longer! However, both water creatures have long lifespans.

On average, alligators have a lifespan of about 30 to 60 years. At the same time, the lifespan of a crocodile is between 70-100 years. These animals live for a long period of time and grow into monstrous sizes. That’s why crocodiles are the staple predators!

Crocodiles have lighter colors than alligators. They can be a light tan or olive green, or brown color. On the other hand, alligators are usually dark blackish-grey in color. Also, the shade of the alligator’s skin depends on the water he is living in. The algae in the water make them greener, and the tannic acid from overhanging trees will make them darker.

Both creatures have sense organs on their skin. These organs are in the form of small pits called integumentary sensory organs (ISOs). They can easily sense and locate the prey with the help of these organs. These ISOs look like small dots are present all over the crocodile’s body but only around an alligator’s mouth.

Alligator vs Crocodile : Predators

Alligator vs Crocodile : Predators

Yes, both alligators and crocodiles are extremely apex predators, but they also have external threats. Yes. It’s hard to believe as they seem like the most dangerous water reptiles.
