Saltwater Crocodile VS Nile Crocodile (Facts)

Saltwater Crocodile VS Nile Crocodile (Facts)

Among many other animals that live in water, reptiles are the deadly ones.

There are 23 species of reptiles, and one of them is the crocodiles. Crocodiles are carnivorous reptiles and belong to the family of Crocodylidae which includes alligators, gavials, and caiman.

Their jaws and teeth are very powerful. They have short legs with clawed toes and thick skin all over the body.

Crocodiles are blessed with such an amazing body that allows their nostrils, ears, and eyes to be above the water while the rest of the body gets hidden inside the water.

All crocodiles possess the feature of a long snout and muzzle and their brain is tiny as compared to their body.

They are the largest and heaviest reptiles. Two of the largest crocodiles are:

  • The Nile crocodile (Crocodylus niloticus)
  • The Saltwater crocodile (Crocodylus prososus)

These both are the largest and heaviest crocodiles of the “true crocodile” family. Their length is up to 6 meters and weigh approximately 2200 pounds.

The Nile Crocodile is found in Africa and the Saltwater Crocodile is found in Australia.

Even though they both are considered deadly creatures and can be dangerous to humans but the major difference between them is:

The Saltwater Crocodiles are much larger and bigger than the Nile Crocodiles and they can be found in both salt water and fresh water while Nile crocodiles can be found in freshwater only.

Interesting Fact: Nile Crocodiles being smaller are more aggressive and deadly than Saltwater Crocodiles with a high ratio of attacks every year.

Also, the body shape of the Saltwater Crocodile and Nile Crocodile is different from each other.

Let’s start.

Are Nile Crocodiles Stronger Than Saltwater Crocodiles?

No, Saltwater Crocodiles are stronger than Nile Crocodiles because they are heavier in size and are more muscular.

Though, the Nile Crocodile’s bite force is much stronger than saltwater crocodile. They attack mammals as well and are mostly found in the fresh waters of Africa.

But, saltwater crocodiles can stay in water for a long time too and have a broad snout with an uneven jawline while Nile crocodiles have a longer snout with a straight jawline.

The saltwater crocodiles are recorded to grow up to 23 feet and 2200 pounds which has earned the title of strongest for them.

It makes them much taller than an elephant.

Can A Saltwater Crocodile Mate with A Nile Crocodile?

I don’t think a Saltwater crocodile can mate with Nile Crocodile. This is because they both live apart and Saltwater Crocodiles are poor swimmers. They can only stay in the water without drinking and eating but cannot cross oceans.

If talking about genetically, they are compatible with each other.

I haven’t heard of any evidence about their mating, but one thing I know is that Saltwater interbreeds with Siamese Crocodiles and Nile Crocodiles have as many chromosomes as Siamese crocodiles chromosomes.

Also, there is no big reason to mate them because they both belong to the same family of crocodilians.

Saltwater crocodile has 32 pairs of chromosomes while Siamese and Nile crocodiles have 30 pairs of chromosomes.

Saltwater Crocodiles don’t play role in parenting, they mate with multiple females at a time and females make nests over their eggs to protect them from being eaten by male Saltwater Crocodiles.

What Is The Most Powerful Crocodile?

The Saltwater Crocodiles are the most powerful because of their bite force of 3700 pounds on a 17-foot crocodile.

This bite force beats the record of the 13-foot American Alligator which has a bite force of 2980 pounds.

It is the size of crocodiles that make them powerful. If a saltwater crocodile is bigger in size hence it will be called more powerful.

So, it would be fair to say that power is directly related to the size of the crocodile.

The bigger in size, the bigger would be their power.

Nile Crocodile is smaller in size hence it is not that powerful because power is measured by the pounds of their bite force.
