Although not a regular sea-going species as is the American crocodile, and especially the saltwater crocodile, the Nile crocodile possesses salt glands like all true crocodiles (but not alligators and caimans), and does on occasion enter coastal and even marine waters.  However, Alderton (1998) stated that a study using radiology found that gastroliths were seen to internally aid the grinding of food during digestion for a small Nile crocodile. "Spatial distribution of lion kills determined by the water dependency of prey species", "Social signals and behaviors of adult alligators and crocodiles", "A new horned crocodile from the Plio-Pleistocene hominid sites at Olduvai Gorge, Tanzania", The forensic identification of crocodilian hides and products, "Structure, innervation and response properties of integumentary sensory organs in crocodilians", "Reptilian heart development and the molecular basis of cardiac chamber evolution", "Crocodylian snouts in space and time: phylogenetic approaches toward adaptive radiation", "Insights into the Ecology and Evolutionary Success of Crocodilians Revealed through Bite-Force and Tooth-Pressure Experimentation", "Non-detriment Finding Studies on Nile Crocodile (, 10.2305/IUCN.UK.2019-1.RLTS.T46584A3009688.en, "A Cultural Herpetology of Nile Crocodiles in Africa", "Nile Crocodiles Found Really Far Out of Africa.  In attempts to parse the mean male and female lengths across the species, the mean adult length was estimated to be reportedly 4 m (13 ft 1 in) in males, at which males would average about 280 kg (620 lb) in weight, while that of the female is 3.05 m (10 ft 0 in), at which females would average about 116 kg (256 lb).  In yet another historic crocodile stronghold, the Olifants River, which flows through Kruger National Park, numerous crocodile deaths have been reported. Like all crocodiles they are sexually dimorphic, with the males up to 30% larger than the females, though the difference is even more in some species, like the saltwater crocodile. I noticed that they are in the same genus. It depends on that particular individual’s “personality” traits, simples. size matters for crocs so slat water wills heres what happens. The comparison and difference between Nile crocodile vs Australian Salt water crocodile are given below.  The Nile crocodile has a reputation as a voracious and destructive feeder on freshwater fish, many of which are essential to the livelihoods of local fisherman and the industry of sport fishing. Sorry, Guinness lists the record at 20.24 feet (6.17 meters) long, 2,370-pound (1,075-kilogram) indo-pacific salty caught outside Bunawan township, Philippines. (1997).  A variety of snakes has been preyed on from relatively small, innocuous species such as the common egg-eating snake (Dasypeltis scabra) to the largest African snakes species, the African rock python (Python sebae), which can exceed 6.1 m (20 ft 0 in) in length and weigh over 91 kg (201 lb). Never has any crocodile been weighed over 1100kg. The population was severely depleted, and the species faced extinction. Among the larger males of a population, territorial clashes can lead to physical fighting between males especially if they are near the same size. , Numerous birds, including storks, small wading birds, waterfowl, eagles, and even small, swift-flying birds, may be snatched. Particularly small fish are likely to be eaten only in case of sudden encounter, mostly in shallow, dry-season ponds where not much effort is needed to catch the small, agile prey. , The Nile crocodile is the largest crocodilian in Africa, and is generally considered the second-largest crocodilian after the saltwater crocodile. Like Nile monitors, mammalian predators probably locate crocodile nests by scent as the padded-down mound is easy to miss visually. The Nile crocodile is a member of the animal class Reptilia, which contains the Orders Squamata (snakes and lizards), Testudines (tortoises, terrapins and turtles), Rhynchocephalia (the two tuatara species of New Zealand) and Crocodylia (crocodiles, including alligators).These are ancient reptile groups that are distantly related, although the Crocodylia are more closely related to birds.  Intimidation displays may also resolve these conflicts. In 1993, 80,000 Nile crocodile skins were produced, the majority from ranches in Zimbabwe and South Africa.  The Nile crocodile is a strong example of an apex predator. 2. 1.0 to 1.5 m (3 ft 3 in to 4 ft 11 in), and become commonplace in subadult and small adult crocodiles.  Most observed fishing by crocodiles takes place in waters less than 1.5 m (4 ft 11 in) deep and fish are often caught when they swim into contact with the crocodile's head, even literally right into the reptile's mouth. , Evidence exists of Nile crocodiles from cooler climates, like the southern tip of Africa, being smaller, and may reach maximum lengths of only 4 m (13 ft 1 in).  Crocodile farming is one of the few burgeoning industries in Zimbabwe.  The Nile crocodile's current range of distribution extends from the regional tributaries of the Nile in Sudan and Lake Nasser in Egypt to the Cunene of Angola, the Okavango Delta of Botswana, and the Olifants River in South Africa. Who will win the fight? However, it pales in comparison to its saltwater cousin and the other large crocodiles on this list and is really not a fatal threat to humans, though they can certainly deliver an unpleasant bite. Gustave is a large male Nile crocodile from Burundi.He is notorious for being a man-eater, and is rumored to have killed as many as 300 people from the banks of the Ruzizi River and the northern shores of Lake Tanganyika.Though the actual number is difficult to verify, he has obtained near-mythical status and was greatly feared by people in the region.  In Uganda and Zambia, lungfish comprised nearly two-thirds of the piscivorian diet for crocodiles. The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries. 2 cases of Leopards preying on Crocodiles were reported. , In general, reptiles become relatively common only in the diet in larger juvenile specimens and subadults. Here, the crocodiles may line up in dozens across narrow straits of the estuary to effectively force the mullet into easy striking distance, with no observed in-fighting among these crocodile feeding congregations. Most Crocodiles are rarely challenged by anything other than Hippos, Rhinos or Elephants.  According to Cott (1961), the average length and weight of Nile crocodiles from Uganda and Zambia in breeding maturity was 3.16 m (10 ft 4 in) and 137.5 kg (303 lb). Breeding females along the Olifants were overall larger than those in Zimbabwe. If the temperature inside the nest is below 31.7 °C (89.1 °F), or above 34.5 °C (94.1 °F), the offspring will be female. Carefully simmered in a nice white wine sauce (eg.  Nonetheless, starting around 1.5 m (4 ft 11 in), they can become capable mammalian hunters and their ability to overpower a wide range of mammals increases along with their size. (1971). I actually think the biggest crocodiles are those found in the Mara river in Kenya. Much of the hunting of and general animosity toward Nile crocodiles stems from their reputation as a man-eater, which is not entirely unjustified. Never. , The bulk and mass of individual crocodiles can be fairly variable, some animals being relatively slender, while others being very robust; females are often bulkier than males of a similar length.  The CITES lists the Nile crocodile under Appendix I (threatened with extinction) in most of its range; and under Appendix II (not threatened, but trade must be controlled) in the remainder, which either allows ranching or sets an annual quota of skins taken from the wild.  However, despite their robust skulls, alligators and caimans appear to be proportionately equal in biting force to true crocodiles, as the muscular tendons used to shut the jaws are similar in proportional size. The previous captive record-holder was a 17.97-foot-long (5.48-meter-long) Australian-caught saltwater crocodile.  Though the Nile crocodile has been hunted since ancient times, the advent of the readily available firearm made it much easier to kill these potentially dangerous reptiles. Such predators that can find themselves victim to crocodiles include hyenas (3 out of 4 species reported as prey for Nile crocodiles, only the desert-dwelling brown (Hyaena brunnea) being excluded), African wild dogs, jackals, and cheetahs (Acinonyx jubatus). These mammals are the biggest meat-eating predator in the world, there is no way a salty could even hope to survive any contact with the killer whale under any circumstances almost, short of an already injured or ill killer whale or some other catastrophic injury to the whale. The Great White refuses to let a Crocodile defeat so he tries to bite the Nile Crocodile, but it only bite the Nile Crocodile on the back. Crocs do eat bull sharks all the time though. , The type and size of the prey depends mostly on the size of the crocodile. They are ambush predators that can wait for hours, days, and even weeks for the suitable moment to attack. It is known for its death roll, it grabs its prey and roll it powerful until prey died.  Dispersal across the Atlantic is thought to have occurred 5 to 6 million years ago. , In a search for the largest crocodilian skulls in museums, the largest verifiable Nile crocodile skulls found were several housed in Arba Minch, Ethiopia, sourced from nearby Lake Chamo, which apparently included several specimens with a skull length more than 65 cm (26 in), with the largest one being 68.6 cm (27.0 in) in length with a mandibular length of 87 cm (34 in). (1956).  Based on morphology, time, and placement of fossils, C. checchiai are thought to essentially form a link between the Nile crocodile and today's Neotropical crocodiles.  For males, the onset of sexual maturity occurs when they are about 3.3 m (10 ft 10 in) long and mass of 155 kg (342 lb), being fairly consistent. The Saltwater has the strongest psi of any extant animal. In Botswana, arachnids were more often found in young crocodiles than in Uganda and Zambia.  Earlier studies support that breeding is often inconsistent in females less than 3 m (9 ft 10 in) and clutch size is smaller, a female at 2.75 m (9 ft 0 in) reportedly never lays more than 35 eggs, while a female measuring 3.64 m (11 ft 11 in) can expect a clutch of up to 95 eggs. The underwater ability combined with their speeds and make them very dangerous hunter for larger animals as well. Compared to the tender behaviour of the female accepting the male, copulation is rather rough (even described as "rape"-like by Graham & Beard (1968)) in which the male often roars and pins the female underwater.  In South Africa, a game warden far from water sources in a savannah-scrub area reported that he saw a crocodile jump up and grab a donkey by the neck and then drag the prey off. Amongst salties you get huge variations in aggression, as with nile crocodiles.  In "stunted" newly mature females from Lake Turkana measuring 1.83 m (6 ft 0 in), the average clutch size was only 15. Go further to know about it. Based on these findings, it has also been suggested that crocodiles may act as seed dispersers.  A more contemporary study claimed the number of attacks by Nile crocodiles per year as 275 to 745, of which 63% are fatal, as opposed to an estimated 30 attacks per year by saltwater crocodiles, of which 50% are fatal.  While adults have a sufficient bite force to crush turtle shells, younger crocodiles sometimes are overly ambitious, and will choke to death attempting to swallow whole large river turtles. Like other crocodiles, Nile crocodiles have an extremely powerful bite that is unique among all animals, and sharp, conical teeth that sink into flesh, allowing for a grip that is almost impossible to loosen. Hippopotamus calves have been observed to at times act brazenly around crocodiles, foraging without apparent concern and even bumping into the reptiles. Have you actually seen the very biggest nile crocodiles in the Mara river in Kenya? The crocodile population in this area is much more sparse, and has not been adequately surveyed. In Madagascar, the remnant population of Nile crocodiles has adapted to living within caves.  On the contrary, several records exist of them capturing wading birds. When it comes to larger prey, success depends on the crocodile's body power and weight to pull the prey item back into the water, where it is either drowned or killed by sudden thrashes of the head or by tearing it into pieces with the help of other crocodiles. Thorbjarnarson, J.  However, some large crocodiles have been recorded as predators of subadult hippos; anecdotally, the infamous giant crocodile Gustave was reported to have been seen killing adult female hippos. They have been spotted in Zanzibar and the Comoros in modern times, but occur very rarely. It makes its prey off balance and making easier to drag the prey to water.  Young crocodiles feed more actively than their elders according to studies in Uganda and Zambia. , Isolated populations also exist in Madagascar, which likely colonized the island after the extinction of voay.  Unlike American alligator flesh, Nile crocodile meat is generally considered unappetizing although edible as tribes such as the Turkana may opportunistically feed on them. Nile crocodiles are relatively social crocodiles. In order to handle, 16 foot salt crocodile, an average of 10 strong men are required.  The largest fishes attacked in such cases may potentially weigh more than 45 kg (99 lb). Nests have been recorded seldom in concealed positions such as under a bush or in grasses, but normally in open spots on the bank. More time is spent in water in overcast, rainy, or misty days. Saltwater Crocodile Dubbed 'Croc-zilla' Spotted at Australian Harbor Croc Has Jaws Taped Shut in 'Deplorable' Act as Rescue Operation Launched 6-Foot-Long Crocodile … , Other fossil species from Africa are retained in Crocodylus and appear to be closely related to the Nile crocodile: namely C. checchiai from the Miocene in Kenya, C. anthropophagus from Plio-Pleistocene Tanzania, and C. thorbjarnarsoni from Plio-Pleistocene Kenya.  The mother crocodile may pick up the eggs in her mouth, and roll them between their tongue and the upper palate to help crack the shell and release her offspring. Poole, Alan F., Rob O. Bierregaard and Mark S. Martell. Even swift prey are not immune to attack.  Other studies have also shown a large number of adult Nile crocodiles with empty stomachs. The Saltwater crocodile is the winner and makes for better eating. An ideal place for animal versus animal comparison. Richardson, K.C., G.J.W. It was approximately 6,2 meters long. Agreed. Osprey (.  It is unknown how many Nile crocodiles are currently at large in Florida. Nile crocodile is heavier and has stronger bite force but when it is compare with salty crocodile then they both have similar jaw structure. , The bite force exerted by an adult Nile crocodile has been shown by Brady Barr to measure 22 kN (5,000 lbf). They can even eat larger sharks; you can see shark remains in their stomachs.  Additional ecological surveys and establishing management programs are necessary to resolve these questions. I would also suggest deleting or editing your data so as not to mislead others.  They have been known to enter the sea in some areas, with one specimen having been recorded 11 km (6.8 mi) off St. Lucia Bay in 1917.  In the southern reaches of their range, as a response to dry, cool conditions that they cannot survive externally, crocodiles may dig and take refuge in tunnels and engage in aestivation. Lolong, by the way, is also the longest saltie ever measured. , Nile crocodiles may be able to tolerate an extremely broad range of habitat types, including small brackish streams, fast-flowing rivers, swamps, dams, and tidal lakes and estuaries. Natural predation on quelea.  Extremely large fish, such as Nile perch (Lates niloticus), goliath tigerfish (Hydrocynus goliath), and even sharks, are taken on occasion, in addition to big catfish, such as Bagrus spp.  The stomachs of brooding females are always empty, meaning that they can survive several months without food. It swims with same speed as of dolphin. Many people consider it as endangered species but it is common species and not an endangered one. , Particularly large adults, on occasion, take on even larger prey, such as giraffe (Giraffa camelopardalis), Cape buffalo (Syncerus caffer), and young African bush elephants (Loxodonta africana). awesome content but you should rank your page higher in search engines. It has power to pull water buffalo of 2200 pounds. Since a majority of fatal attacks are believed to be predatory in nature, the Nile crocodile can be considered the most prolific predator of humans among wild animals. saltwater crocodile bite force: 7500 psi  Crocodiles are occasionally successful in grabbing passerines such as weaver birds, including the abundant red-billed quelea (Quelea quelea), and swallows, having been observed to breach the water and in a matter of seconds sweep off a branch full of birds with remarkable success. The status of Nile crocodiles was variable based on the regional prosperity and extent of conserved wetlands by the 1970s. Anyways, it could go either way, but I have my cash on the saltwater.  Across much of their range, they take any fish they encounter, but largish and relatively sluggish mesopredator fish such as lungfish and Barbus carp seem to be most widely reported. Want to see an 8m saltwater crocodile? Saltwater crocodile have more stamina under water and faster in comparison to Nile crocodile. Saltwater Crocodiles are also known to kill Water Buffalo. The Great White realized how it killed the Saltwater Crocodile, which was by biting it's soft underbelly.  In one case, a crocodile was filmed capturing a striated heron (Butorides striata) in mid-flight.  Crocodiles as small as 2.1 m (6 ft 11 in) are capable of overpowering and successfully preying on small apes and hominids, presumably including children and smaller adult humans, but a majority of fatal attacks on humans are by crocodiles reportedly exceeding 3 m (9 ft 10 in) in length. While C. checchiai was about the same size as the larger modern Nile crocodiles, and shared similar physical characteristics to the modern species; C. anthropophagus and C. thorbjarnarsoni were both somewhat larger, with projected total lengths up to 7.5–7.6 m (24 ft 7 in–24 ft 11 in). West African crocodiles are found throughout much of West and Central Africa, ranging east to South Sudan and Uganda where the species may come into contact with the Nile crocodile. Gastroliths are not present in hatchlings, but increase quickly in presence within most crocodiles examined at 2–3.1 m (6 ft 7 in–10 ft 2 in) and yet normally become extremely rare again in very large specimens, meaning that some animals may eventually expel them.  In the Okavango Delta, Botswana, the diet was similar but young crocodiles ate a broader range of insects and invertebrates, with beetles taken in similar numbers to other, similar prey, both aquatic and terrestrial. , In the Nile crocodile as well as in at least 13 other species of crocodilian, a variety of fruit (mostly fleshy) has been found in stomach content.  Hatchlings quickly lose a hardened piece of skin on the top of their mouths called the egg tooth, which they use to break through their eggshells at hatching.  Additional factors are a loss of wetland habitats, which is addition to direct dredging, damming and irrigation by humans, has retracted in the east, south and north of the crocodile's range, possibly in correlation with global warming. A saltwater crocodile does not have a stronger bite force than a Nile crocodile period.  The Nile crocodile also consumes dead animals that would otherwise pollute the waters. Of the insects taken there, beetles made up 58% of the diet, including Hydrophilus and Cybister. Small, E. (2013).

They can swim much faster by moving their bodies and tails in a sinuous fashion, and they can sustain this form of movement much longer than on land, with a maximum known swimming speed 30 to 35 km/h (19 to 22 mph), more than three times faster than any human. A Nile Crocodile can weigh up to a tonne, measuring up to 5.45 meters long, and have a bite force nearing 5500 PSI. Philippines Crocodiles are the most dangerous and are much heavier than the Nile and much bigger/ and loger than the Australian Crocs. Retrieved on 2013-04-25. The saltwater crocodile is considered a sister taxon of the Siamese and the Nile crocodile. , Hatchling Nile crocodiles are between 280 and 300 mm (11 and 12 in) long at first and weigh around 70 g (2.5 oz). The “winners”—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force.
