Alligator vs. Crocodile: What are They and What is Different?

alligator vs crocodile

Alligators and crocodiles are two reptiles with remarkable similarities – but also some big differences. Their distinctions include habitat, physical characteristics, and behavior. Alligators have a broader V-shaped snout, while crocodiles have a more pointed U-shaped snout.


  • Alligators – Freshwater habitats like swamps, rivers, lakes, and ponds.
  • Crocodiles – Saltwater habitats like estuaries, deltas, and lagoons.

Physical Characteristics:

Alligator vs Crocodile differences

  • Alligators – Broad and rounded snout. The upper jaw visible when the mouth is closed. Darker in color.
  • Crocodiles – Longer and pointed snout. Both jaws are visible when the mouth is closed. Lighter in color with a salt gland above the eyes.


  • Alligators – Less aggressive towards humans, but more territorial. Spend most of their time basking on the shore or floating on water.
  • Crocodiles – More prone to attack humans, but less territorial. Often sunning themselves on rocks and logs in water bodies.

To stay safe when living near or visiting natural habitats of alligators and crocodiles, avoid swimming at night – they are more active then. Also, don’t intrude into an alligator’s territory or provoke a provoked crocodile. It’s like a game of ‘spot the Subaru’ – these prehistoric-looking beasts are not easy to tell apart!

More about Physical Characteristics

Alligators and crocodiles are reptiles that share some features. However, they have different physical appearances. A comparison of them shows unique attributes that set them apart.

A table can show how they differ. Alligators have a U-shaped mouth with a wider snout. Crocodiles have a V-shaped snout with interlocking teeth which are seen when their mouths are closed.

Alligator limbs are short and stout. Crocodile legs are longer and stronger. They are better suited for aquatic environments. Alligators have only four teeth visible when their mouths are shut. Crocodiles can show many more teeth in the same position.

Adult male crocodiles can be up to 5 meters long. Male alligators are only 4 meters long. Female alligators are smaller than female crocodiles.

Pro Tip: Enjoy these creatures from a distance. They are powerful and have lethal bites.

More about Behaviors and Lifestyle


Alligators and crocodiles have different lifestyles. They vary in size, social structure, habitat, diet, and reproduction strategies. Alligators have powerful jaws that can crack a turtle shell. Crocs can snatch fish and mammals quickly. Both prefer warm climates but use distinct methods for hibernation and living in groups.

Alligators feed on fish and create nests for their eggs in freshwater. Crocodiles eat large mammals in saltwater estuaries and wander over land. To survive cold weather, alligators burrow under ice sheets while crocs use warm mud pits for heat conservation. They also have gender differences in size and color.

Sadly, human activities and climate change have decreased their population. People hunted them for leathery skin to make boots, belts, and handbags. Fortunately, they are now protected species. Let’s hope they don’t start eyeing each other for dinner!

More about Feeding Habits

Alligators love fish, turtles, and small mammals! Crocodiles, however, prefer larger mammals and birds. Alligators lurk in the water for prey while crocs aggressively hunt on land or water. They even use their powerful jaws to drag larger animals into the water.

No need to fear these reptiles yet, as further research will show more features. But beware – they both love snacking on humans!

Threats to Humans



Wildlife Encounters: Risks for Human Safety.

Alligators and crocodiles are huge threats to human safety. If attacked, fatalities are common. Even when unprovoked, they will attack someone too close to their habitat.

These reptiles are ambush hunters. That means they hide and wait for prey to come near before attacking. Even experienced pros need to be careful when dealing with them. Injury or death is possible if safety protocols are not followed.

We must remember crocodilians are wild animals that need respect. Keep a safe distance, don’t go near them while they eat or mate, don’t swim in places they live and don’t interfere with their behavior.

In 1898 a group of soldiers in Sudan were attacked by Nile crocodiles while crossing a river. Only two survived, causing widespread fear among British troops in Africa.

For these reptilian rivals, conservation status is grim. Humans are their biggest threat. Good luck!

Conservation Status

Alligators are listed as the Least Concern, while some species of Crocodiles like the Philippine and Estuarine Crocodiles are Vulnerable and Endangered. Conservation efforts are in place to protect alligators, like limiting hunting and ensuring habitat protection. Crocodiles, however, are still threatened due to urbanization, fragmentation and illegal trade of their skin and body parts.

It is vital to raise awareness of conservation efforts for these apex predators, as they maintain aquatic ecosystems. Through the protection of their habitats, their populations can be restored and future human-wildlife conflicts can be avoided.

In fact, National Geographic has reported that crocodiles use tools like sticks or branches to lure birds close by. So if you’re ever faced with an alligator and a crocodile, don’t count on coming out unscathed!

Alligator vs. Crocodile – Which is stronger?

Small aligator and crocodile

The strength of alligators and crocodiles has long been a topic of debate among wildlife fanatics. To compare the two, experts have presented a table based on scientific research. The table details bite force, size, and habitat preferences of each species.

Crocodiles have a greater bite force of 3,700 PSI as opposed to alligators at 2,125 PSI. On the flipside, alligators are smaller and prefer freshwater rivers and lakes while crocodiles opt for saltwater environments. Additionally, both species are descendants of prehistoric reptiles that lived over 200 million years ago. So, no definitive answer can be given as to which is stronger. Both animals are fearsome predators in their respective habitats.
