While not as extensively aquatic as the genus Kobus, the reedbucks and the impala (Aepyceros melampus) have both shown a partiality for grasslands adjoining wetlands and riparian zones, so are also very commonly recorded prey items.  Recovery for the species appears quite gradual and few areas have recovered to bear crocodile populations, i.e.  They also feed on dead hippopotamuses (Hippopotamus amphibius) as a group (sometimes including three or four dozen crocodiles), tolerating each other.  Despite most attacks going unreported, the Nile crocodile along with the saltwater crocodile is estimated to kill hundreds (possibly thousands) of people each year, which is more than all other crocodilian species combined. These may include Grévy's (Equus grevyi) and plains zebras (Equus quagga), pygmy hippopotamus (Choeropsis liberiensis), warthogs (Phacochoerus africanus), bushpigs (Potamochoerus larvatus) and red river hogs (Potamochoerus porcus). More modestly sized fish are generally swallowed whole. Mammalian carnivores take many hatchlings as well as large turtles and snakes, large predatory freshwater fish, such as the African tigerfish, the introduced largemouth bass, and possibly bull sharks, when they enter river systems. They grab such prey in their powerful jaws, drag it into the water, and hold it underneath until it drowns. , Herodotus claimed that Nile crocodiles have a symbiotic relationship with certain birds, such as the Egyptian plover (Pluvianus aegyptius), which enter the crocodile's mouth and pick leeches feeding on the crocodile's blood, but no evidence of this interaction actually occurring in any crocodile species has been found, and it is most likely mythical or allegorical fiction. i’m just going to set this straight, the salt water crocodile weights 900-1100 kg’s, was thicker and harder scales, is smarter (proven to be the smartest of all reptiles by scientist’s), has a much stronger bite (7,500 psi), is longer (5.5-7.5 meters) and is faster (in water). Niche crocodile diet includes reptiles, fish, mammals, birds etc. In one area, 17 craters were found in an area of 25 yd × 22 yd (75 ft × 66 ft), in another 24 in an area of 26 yd × 24 yd (78 ft × 72 ft). Some deaths of crocodiles appeared to have been caused by these dangerous saline levels and this one-time stronghold for breeding crocodiles has experienced a major population decline.  Since their speed and agility on land is rather outmatched by most terrestrial animals, they must use obscuring vegetation or terrain to have a chance of succeeding during land-based hunts. Lolong, by the way, is also the longest saltie ever measured. Compare Nile Crocodile vs Salt Water Crocodile.  Mature female Nile crocodiles typically measure 2.2 to 3.8 m (7 ft 3 in to 12 ft 6 in), at which lengths the average female specimen would weigh 40 to 250 kg (88 to 551 lb). In Uganda and Zambia, the latter species are the leading overall mammalian prey type for crocodiles and one Kenyan crocodile of 2.7 m (8 ft 10 in) in length had 40 greater cane rats in its stomach. The salty could not only overpower it because of sheer size, but they are an over all more dangerous predator simply because they can cover much more territory including salt waters.  This species’ historic range, however, was even wider. (1993).  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. Crocodiles & alligators of the world.  According to the Guinness Book of World Records, the typical mature size is between 3.4 and 3.7 m (11 ft 2 in and 12 ft 2 in), while Alexander and Marais (2007) state it is 2.8 to 3.5 m (9 ft 2 in to 11 ft 6 in) and Garrick and Lang (1977) claim from 3.0 to 4.5 m (9 ft 10 in to 14 ft 9 in). As pointed out earlier, you have conflicting and false information in your article. 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. The female digs a hole a few metres from the bank and up to 0.5 m (20 in) deep, and lays on average between 25 and 80 eggs.  In one case, an adult crocodile charged from the water up a bank to kill a bushbuck (Tragelaphus scriptus) and instead of dragging it into the water, was observed to pull the kill further on land into the cover of the bush. Bite force was measured at 5000 lbf, or over 22kN by Brady Barr, which is equivalent to 3,700 psi or 25.5 MPa, on par with a saltwater crocodile) Speed: Below Average Human on land (A galloping crocodile can reach 14 km/h), Athletic Human in water (Nile crocodiles can swim up to 30-35 km/h in water), Superhuman combat speed and reactions (Can grab humans, gazelles and zebras before they can … , Adult Nile crocodiles have a dark bronze colouration above, with faded blackish spots and stripes variably appearing across the back and a dingy off-yellow on the belly, although mud can often obscure the crocodile's actual colour. Nile crocodiles on occasion prey on big cats including lions and leopards.  In Limpopo, South Africa, males reportedly average 527 kg (1,162 lb). National Geographic has exclusive video of a jaguar taking down a caiman in Brazil’s Pantanal wetlands, photos of which went viral earlier this month. Adults can eat young Hippo, buffalos, zebras, hyenas, warthlogs, antelope, baboons, giraffe, wildebeest and big cats. It is known as the king of Nile delta. With the Nile crocodile and the saltwater crocodile, the mean size of crocodiles involved in non-fatal attacks was about 3 m (9 ft 10 in) as opposed to a reported range of 2.5–5 m (8 ft 2 in–16 ft 5 in) or larger for crocodiles responsible for fatal attacks. Your article is simply not a reliable source of information.  In some regions, males have reportedly mated with several females, perhaps any female that enters his claimed territory, though in most regions annual monogamy appears to be most common in this species. This is why I hate the internet. When compared to Nile crocodiles from their native Africa, the Florida wild specimens are most closely related to South African Nile crocodiles. Young crocodiles are rather shy and evasive due to the formidable gaunlet of predators that they must face in sub-Saharan Africa, spending little time sunning and moving about nocturnally whenever possible.  Larger land birds, such as bustards, guineafowl, ground hornbills (Bucorvus spp.)  At some point in the 20th century, the Nile crocodile appeared to have been extirpated as a breeding species from Egypt, but has locally re-established in some areas such as the Aswan Dam. More time is spent in water in overcast, rainy, or misty days.  It is widely distributed throughout sub-Saharan Africa, occurring mostly in the central, eastern, and southern regions of the continent, and lives in different types of aquatic environments such as lakes, rivers, swamps, and marshlands. The benefits of this are presumably that nest flooding risk is considerably reduced at this time and the stage at which hatchlings begin their lives out of the egg falls roughly at the beginning of the rainy season, when water levels are still relatively low but insect prey is in recovery. Nile crocodile has more rough and thick skin. They are ambush predators that can wait for hours, days, and even weeks for the suitable moment to attack. …Did you just make up all this shit one day or what?? Much of the contamination of crocodiles occurs when they consume rancid fish themselves killed by pollutants.  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. 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.  Once a female has been attracted, the pair warble and rub the undersides of their jaws together. Occasionally, if regular food becomes scarce, both lions and the crocodile will steal kills on land from each other and, depending on size, will be dominant over one another. , Numerous birds, including storks, small wading birds, waterfowl, eagles, and even small, swift-flying birds, may be snatched.  The only frequently recorded lizard prey is the large Nile monitor (Varanus niloticus), although this mesopredator may be eaten fairly regularly, as they often share similar habitat preferences, whenever a crocodile is able to ambush the stealthy monitor, which is more agile on land than the bulkier crocodile. As cold-blooded creatures, Nile crocodiles need to eat far less compared to an equivalent-weighted warm-blooded animal. In the Zambezi River and Lake St. Lucia, Nile crocodiles have been known to prey on bull sharks (Carcharhinus leucas) and sand tiger sharks (Carcharias taurus). Growing to around 20 feet in length, it is the largest extant species of reptilian predator in the world, even larger than the Nile Crocodile. Dodman, T., Dagou Diop, N.M. & Khady, S. Mollusks may occasionally be taken by young crocodiles (they are taken in larger numbers later in life in parts of Uganda and Zambia). In general, at the smallest sizes (0.3–1 m (1 ft 0 in–3 ft 3 in)), Nile crocodiles were most likely to have full stomachs (17.4% full per Cott); adults at 3–4 m (9 ft 10 in–13 ft 1 in) in length were most likely to have empty stomachs (20.2%).  The distributional boundaries between these species were poorly understood, but following several studies, they are now better known. This is rarely recorded in wild crocodiles, normally having been observed in cases where humans have mishandled crocodiles and put them through overly extended periods of physical struggling and stress. Micheal: I agree that to me the Saltwater Crocodile is the most terrifying predator in the world (other than humans as we have weapons that will kill them easily) but I can’t see a saltwater croc having much luck against a full-grown male killer whale!  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. but against any other animal are pretty much untouchable. Breeding females along the Olifants were overall larger than those in Zimbabwe. Who will win the fight between Nile Crocodile and Salt Water Crocodile?  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. The species, however, also has small, oval osteoderms on the sides of the body, as well as the throat. Nile crocodiles are absent from most of West and Central Africa, but range into the latter region in eastern and southern Democratic Republic of Congo, and along the Central African coastal Atlantic region (as far north to Cameroon).  Despite historic claims that the victims of Nile crocodile attacks are usually "women and children", there is no detectable trends in this regard and any human, regardless of age, gender, or size is potentially vulnerable.  An additional case of predation on an adult black rhino was reportedly observed in northern Zambia. 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 …  The new mother will protect her offspring for up to two years, and if there are multiple nests in the same area, the mothers may form a crèche. the biggest animal it hunts are water buffalo, sharks of all species, mainly bull sharks and occasionally white sharks, cows, pigs, boar, horse, kangaroo, dingo, snakes, fish, crabs, birds, bats, insects and frogs (when young) and any other animal including fresh water and young salt water crocodiles.  While these species are much more aggressive toward people than other living crocodilians (as is statistically supported by estimated numbers of crocodile attacks), Nile crocodiles are not particularly more likely to behave aggressively to humans or regard humans as potential prey than saltwater crocodiles.  While the mother crocodile will react aggressively toward potential predators and has been recorded chasing and occasionally catching and killing such interlopers into her range, due to the sheer number of animals who feed on baby crocodiles and the large number of hatchlings, she is more often unsuccessful at deflecting such predators. The number of eggs varies and depends partially on the size of the female.  However, other than rare instances, adults of megafauna species such as hippopotamuses, rhinoceroses, and elephants are not regular prey and are not typically attacked, with the exception of giraffes, since their anatomy makes them vulnerable to attack while taking a drink. Hyenas, lions, and tigers generate around 1,000 psi (4,450 newtons). If you don’t know 2017 seo techniues search on youtube: Phylogenetic research gave the analyses that indicate that Crocodylus metamorphosed in the Oligocene Indo-Pacific, about 19.3 to 25.5 million years ago.  Females will not leave nest site even if rocks throw at her back and several authors note her trance-like state while standing near nest, similar to crocodiles in aestivation but not like any other stage in their life-cycle. A saltwater crocodile does not have a stronger bite force than a Nile crocodile period. , Predators of Nile crocodiles eggs have ranged from insects such as the red flour beetle (Tribolium castaneum) to predators as large and formidable as spotted hyenas (Crocuta crocuta). For instance I always believed Siberian Tigers were the biggest living felids, but now not only are Bengal Tigers said to be bigger but Lions are bigger still. , An estimated 250,000 to 500,000 individuals occur in the wild today.  Most females nest only every two to three years while mature males may breed every year. Strength and tantic wise- The saltwater crocodile waits for prey to come close to water edge and then strike hard at prey without giving any warning and with his strength drag the animal into the water. , In a study, the serrated hinged terrapin (Pelusios sinuatus) (also sometimes referred to as the "water tortoise") was more commonly reported in the stomach contents of adult crocodiles from Kruger National Park than any single mammal species. , Wading birds, even large and relatively slow-moving types such as the goliath heron (Ardea goliath), tend to be highly cautious in avoiding deep water in crocodile-occupied wetlands, whereas cormorants and waterfowl forage over deeper water and are easier for crocodiles to ambush, with Egyptian geese (Alopochen aegyptiaca) and spur-winged geese (Plectropterus gambensis) recorded as being taken largely while flightless due to molting their flight feathers.  The taking of commercially important fish, such as Tilapia, has been mentioned as a source of conflict between humans and crocodiles, and used as justification for crocodile-culling operations; however, even a primarily piscivorous crocodile needs relatively so little fish that it cannot deplete fish populations on its own without other (often anthropogenic) influences. A smaller population from Mali, the Sahara Desert, and elsewhere in West Africa reaches only 2 to 3 m (6 ft 7 in to 9 ft 10 in) in length, but it is now largely recognized as a separate species, the West African crocodile. Retrieved on 2013-04-25.  All domesticated ungulates and pet animals will on occasion be hunted by Nile crocodiles, up to the size of dromedary camels (Camelus dromedarius) and cattle (Bos taurus) In Tanzania, up to 54 head of cattle may be lost to crocodiles annually, increasing the human-crocodile conflict level. , The Nile crocodile possesses unique predation behavior characterized by the ability of preying both within its natural habitat and out of it, which often results in unpredicted attacks on almost any other animal up to twice its size. How come no one measures them?  They also cooperate, blocking migrating fish by forming a semicircle across the river. The Nile crocodile—four of which have been found in the state's swamps since 2000—are more dangerous than the native crocodiles and alligators, scientists say.  Genetic studies of Nile crocodiles captured in the wild in Florida have revealed that the specimens are all closely related to each other, suggesting a single source of the introduction. , For the crocodile inhabiting west and northwest Africa, see, Natural mortality of young Nile crocodiles. and by the way weight doesn’t matter. 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. , Generally, Nile crocodiles are relatively inert creatures, as are most crocodilians and other large, cold-blooded creatures. Still, it was difficult for someone to know who will win the fight. mate the saltie is heavier, bigger, faster, smarter (in water), stronger and is an apex predator, it eats sharks and has the strongest bite of any animal, show me some evidence that a Nile croc could “easily kill” a saltie.  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. The mother Nile crocodile deposits the eggs in the terminal chamber and packs the sand or earth back over the nest pit. The trouble is I don’t know whether that is tue. There are no living Deinosuchus specimens to hook up to measuring equipment, but extrapolating from the saltwater crocodile — and examining the shape and orientation of this prehistoric crocodile's skull — paleontologists have arrived at a bite force … These communal nesting sites are not known to exist today, perhaps being most recently recorded at Ntoroko peninsula, Uganda where two such sites remaining until 1952.  The stomachs of brooding females are always empty, meaning that they can survive several months without food.  Since crocodiles are solitary hunters, the Nile crocodile is the only predator in Africa known to attack full-grown buffaloes alone, compared to the preferred pride attack method of lions.. Graham (1968) noted that throughout East Africa, crocodile diets are driven by the regional availability of prey. In Kruger National Park, over the course of 22 years of discontinuous observation, 60% of the large-game kills observed as perpetrated by crocodiles consisted of impala, while more than 15% of observed kills were made up of waterbuck (Kobus ellipsiprymnus), the largest of the genus Kobus at more than 200 kg (440 lb) in weight. Which is true I don’t know. The IUCN Red List assesses the Nile crocodile as "Least Concern (LR/lc)". A 16 foot Saltwater Crocodile in Australia had a bite force of 3900 pounds per square inch! (1971). Who will win the fight? I rest my case. Slow-swimming pelicans are also frequently vulnerable to crocodiles. In crocodiles between these distributions egg-laying is in intermediate months, often focused between April and July. The population was severely depleted, and the species faced extinction. "A review of predation on lemurs: implications for the evolution of social behavior in small, nocturnal primates", pp. Most of what else u said is correct though.  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. Required fields are marked *. , Although no subspecies are currently formally recognized, as many as seven have been proposed, mostly due to variations in appearance and size noted in various populations through Africa. Sybney, I understand and had the same dilemma when I read the comparisons. Your email address will not be published. More than 100 species and genera of insects were identified among the food of crocodiles of this age.  After this stage, crocodiles may loosely associate with similarly sized crocodiles and many assuredly enter feeding congregations of crocodiles once they attain 2 m (6 ft 7 in), at which size predators and cannibal crocodiles become much less of a concern. The “winners”—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force. When the narrator says “in same length” they meant when weighed at the same length, but the salties continue to grow larger (2000kg) when the Nile tops out round 1000kg. Multiple, other sources have listed this as a maximum or near maximum size. The (maximal) bite force of the Nile Crocodile ( Crocodylus niloticus) is estimated around 22,000 Newton (refer to YouTube interview with Ofer Kobi, a crocodile conservation ranger and croc farm owner, time 7:50-8:00, Hebrew , where he estimates the bite force as above 2 metric tons). By contrast, you … This predator can destroy about 50% of studied Nile crocodile eggs on its own, often being successful (as are other nest predators) in light of the trance-like state that the mother crocodile enters while brooding or taking advantage of moments where she is distracted or needs to leave the nest. Saltwater Crocodiles are also known to kill Water Buffalo. 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.  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. Although Nile crocodiles are more than a dozen times more numerous than lions in the wild, probably fewer than a quarter of living Nile crocodiles are old and large enough to pose a danger to humans. Don’t be to sure, all crocodiles have heavy armor across their bodies, my perspective is that the killer whale could try and bite a saltwater crocodile, but the armor would more then likely give it protection.
