- Nile crocodiles are the creatures with four-chambered hearts.
- Nile crocodiles are solitary animals, but sometimes they can be seen in small groups.
- During the day-time, these species sunbathe or cool themselves in the water.
- The territory of Nile crocodiles includes the area of shores that extends to 50 meters in water. To defend and protect, the adult males will patrol their territory.
- When these species are threatened, they can be submerged in water for about 30 minutes. When these species are entirely inactive, they can hold breath for 2 hours underwater.
- The Nile crocodiles have metabolism, that they can revive on external heat that allows them to survive for a more extended period between their meals.
Egypt Crocodiles (The Giant Nile Crocodile)
The mating system between these species is polygamous, where one male can mate with several females. Male crocodile attracts the approachable females by making a variety of noises, like bellowing, slapping their snouts in water. During the nesting season, the female crocodile will dig a nest in a riverbank or sandy river. After the incubation of 80-90 days, the female will deliver 25-35 eggs.
Nile Crocodile Endangered:
Under the IUCN red list, these species are classified as least concern. Although the primary threat to these species involves poaching by humans for their skin, which is used for high-quality manufacturing leather, another danger consists of the habitat loss caused by humans.
The Saltwater crocodile is known to be the enormous living crocodile, and also the giant living reptiles in the world. Although the name is salt water, these species can live in both freshwater and brackish water. Other crocodiles can distinguish saltwater crocodiles by their bulky body and the snout, which is more rounded as compared to other species of crocodiles.
Saltwater crocodile Facts:
- The nostrils and eyes situated at the top of the head enable them to survive beneath the water, and yet they can hear, smell, and breathe.
- Unlike Nile crocodiles, these species also have a valve at the end of the mouth that encloses with the throat, which allows them to open their mouth underwater.
- Saltwater crocodile consists of 40 to 60 teeth’s in their mouth, which help them to rip off the flesh of their prey.
- Known to be as excellent swimmers, they can travel long distances as much as 600 miles.
- Saltwater crocodiles are capable of resting following the pattern of uni hemispheric sleep like several other aquatic animals.
- The model involves sleeping with only half of the brain at a time and keeping the other half as active.
- The central nervous system of these species is designed in such a way that the left eye remains open when the right side of the brain is awake and vice-versa.
- Saltwater crocodiles are known to follow a ‘death roll’ which is a hunting behavior constrained for larger prey.
- After the prey submerged and dies, these species rapidly rolls it in the water to remove the limbs of the victim.
- The teeth of the crocodile permit them to grip its prey rather than tearing its flesh. The mode of communication involves a variety of sounds, such as hissing, barking, growling, and chirps.
Estuarine Crocodile (Largest Saltwater Crocodile)
Saltwater crocodiles mate during the wet season when the water level is the highest. The female will lay 40 to 60 eggs after the gestation of 84 to 90 days. When the eggs are about to hatch, the young one makes a chirping sound within their eggs. The sexuality of the young ones will be determined by the temperature of the nest in which eggs are laid. Lower evolution temperature produces females, and higher temperatures will result in males.
By the IUCN red list, the saltwater crocodile is listed as least concern. These species have been hunted for decades for their meat and eggs. Currently, these species are legally protected in Australia and many areas.

Nile Crocodile vs Saltwater Crocodile:
Both creatures have similar physical features, and they also hunt for the same prey. It can be quite challenging to assume who would win if a fight happened between both of them. Saltwater crocodiles can grow more abundant compared to Nile crocodiles, as saltwater crocodiles are native to larger areas.
On the other hand, Nile crocodile is also known as a man-eater; hundreds of humans are killed by Nile crocodiles which shows that Nile crocodiles are more aggressive than saltwater crocodiles. Nile crocodiles get tired faster than a saltwater crocodile, and saltwater crocodiles are known for their death roll process.
