In particular, the genus Kobus is often among the most vulnerable because it forages primarily in wetland areas and seeks to evade more prolific mammalian predators (such as hyenas, lions, etc.)  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. mate i live in Darwin on the Adelaide river, Lolong was the biggest croc in captivity, Krys was an 8.3 meter long saltie who was unfortunately shot in the 90’s, and weighed in at 2.4 tonnes. how to rank a website Marcel’s way.  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. , Regional reportage from numerous areas with large crocodile populations nearby indicate, per district or large village, that crocodiles often annually claim about a dozen or more lives per year. In the water, this species is an agile and rapid hunter relying on both movement and pressure sensors to catch any prey unfortunate enough to present itself inside or near the waterfront.  Also C. anthropophagus and C. thorbjarnarsoni, as well as Rimasuchus spp., were all relatively broad-snouted, as well as large, indicating a specialization at hunting sizeable prey, such as large mammals and freshwater turtles, the latter much larger than any in present-day Africa. Cott (1961) felt that gastroliths were most likely serving as ballast to provide stability and additional weight to sink in water, this bearing great probability over the theories that they assist in digestion and staving off hunger. Phylogenetic research gave the analyses that indicate that Crocodylus metamorphosed in the Oligocene Indo-Pacific, about 19.3 to 25.5 million years ago. Brady Barr, Dangerous Encounters. These have consisted of: C. n. africanus (informally named the East African Nile crocodile), C. n. chamses (or the West African Nile crocodile), C. n. cowiei (the South African Nile crocodile), C. n. madagascariensis (Malagasy or Madagascar Nile crocodile, regionally also known as the Croco Mada, which translates to Malagasy crocodile), C. n. niloticus (would be the nominate subspecies, or the Ethiopian Nile crocodile), C. n. pauciscutatus (Kenyan Nile crocodile), C. (n.) suchus (now widely perceived by crocodilian biologists as a separate species). Saltwater are more aggressive, more ego and usually more faster then Nile crocodiles. Killer whale has strongest bite force of any animal. Large mammalian predators in Africa are often social animals and obligated to feed almost exclusively on terrestrial zones. 2. The nature of the muscle is extremely stiff, almost as hard as bone to the touch, such that it can appear to be the continuum of the skull. They have dark bronze color on above side and black spots at back.  The colouration also helps to camouflage it; juveniles are grey, multicoloured, or brown, with dark cross-bands on the tail and body. Thus they usually attack agile prey in the absence of regular prey items. The trouble is I don’t know whether that is tue.  Most females nest only every two to three years while mature males may breed every year.  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. Gastropoda (4126 records per Cott) were taken much more than Lamellibranchiata (six records). , During the time from when they are roughly 1.5 to 2.2 m (4 ft 11 in to 7 ft 3 in) long (roughly 5 to 9 years old), Nile crocodiles seem to have the broadest diet of any age range. , 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. Nile crocodiles of under two years are much more rarely observed than larger specimens, and more seldom seen than the same age young in several other types of crocodilian. While these are probably sometimes used as gastroliths, they are likely often ingested for their nutritional value. Among crocodilians, the Nile crocodile possesses a relatively long snout, which is about 1.6 to 2.0 times as long as broad at the level of the front corners of the eyes. 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. They have thick, scaly, heavily armoured skin. It has wide snout, less armour plates and longer muzzle. The number of eggs varies and depends partially on the size of the female.  Other large carnivores that dwell in Africa near the top of the food chain can also on occasion fall prey to crocodiles.  However, large specimens can have a large number of gastroliths.  In Lake Turkana, crocodiles rarely bask at all through the day, unlike crocodiles from most other areas, for unknown reasons, usually sitting motionless partially exposed at the surface in shallows with no apparent ill effect from the lack of basking on land. Despite the strong muscles to close the jaw, crocodiles have extremely small and weak muscles to open the jaw.  This species’ historic range, however, was even wider.  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. Nile crocodile in same length is slighty heavier than the Salt water crocodile. 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. But the salties were definitely longer and seemed more active.  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). The crocodile lunges its body out of water in practically the blink of an eye and grasps its prey. The Nile crocodile apparently is more closely related to the crocodiles of the Americas, namely the American (Crocodylus acutus), Cuban (Crocodylus rhombifer), Morelet's (Crocodylus moreletii), and Orinoco crocodiles (Crocodylus intermedius), than to the West African crocodile or other extant African crocodilians. Killer whales weigh on average 6 tons and are 20-26 ft. long! Nile crocodiles on occasion prey on big cats including lions and leopards.  Although capable of living in saline environments, this species is rarely found in saltwater, but occasionally inhabits deltas and brackish lakes.  However, Guggisberg accumulated several earlier writings that noted the lack of fear of crocodiles among Africans, driven in part perhaps by poverty and superstition, that caused many observed cases of an "appalling" lack of caution within view of large crocodiles, as opposed to the presence of bold lions which engendered an appropriate panic. , Among the mammals, the bulk of the prey for adults is antelopes. Saltwater crocodile is known as Indo-Pacific crocodile, it is world largest living reptile which come under terrestrial as well as reptile category. 2 Saltwater Crocodile – Bite Force : 3690 psi.  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.  Even the largest frog in the world, the goliath frog (Conraua goliath), has reportedly been preyed on by young Nile crocodiles.  Dispersal across the Atlantic is thought to have occurred 5 to 6 million years ago. Large reptiles, or armoured reptiles such as turtles, were almost negligible in crocodiles under 2.5 m (8 ft 2 in) and most common in the stomachs of crocodiles over 3.5 m (11 ft 6 in) in length from Uganda and Zambia.  Their diet consists mostly of different species of fish, reptiles, birds, and mammals.  In other areas, the nesting female may disappear upon potential disturbance which may allow the presence of both the female and her buried nest to escape unwanted detection by predators.  As in all crocodilians, Nile crocodiles have exceptionally high levels of lactic acid in their blood, which allows them to sit motionless in water for up to 2 hours. Moleón, M., Sánchez‐Zapata, J.  However, in the Ugandan portion of Lake Victoria, true bugs and dragonflies both seem to outnumber beetles notably and up to a length of 1 to 2 m (3 ft 3 in to 6 ft 7 in) crocodiles had stomach contents that were made up 70–75% of insects.  Similarly, adult crocodiles from Kruger National Park reportedly average 3.65 m (12 ft 0 in) in length. Their ability to lie concealed with most of their bodies under water, combined with their speed over short distances, makes them effective opportunistic hunters of larger prey. Crocodiles & alligators of the world. Frank, L., Hemson, G., Kushnir, H., & Packer, C. (2006, January). If their jaws are bound together in the extreme midday heat, Nile crocodiles may easily die from overheating. The nile crocs were fatter and bulkier.  Their skin has a number of poorly understood integumentary sense organs that may react to changes in water pressure, presumably allowing them to track prey movements in the water. The Nile crocodile is called tanin ha-yeor in Hebrew, timsah al-nil in Arabic, mamba in Swahili, garwe in Shona, ngwenya in Ndebele, ngwena in Venda, and kwena in Sotho and Tswana.  In Lake St. Lucia, highly saline water has been pumped into the already brackish waters due to irrigation practices.  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 saltwater crocodile is classified as a marine reptile, not a terrestrial reptile.  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.  A 5 m (16 ft 5 in) specimen from Zambia was found to have eaten a "half-grown hippo". Nile crocodile has more rough and thick skin. Steven M. Goodman', Sheila O'Connor, and Olivier Langrand, Goodman, S. M., O’Connor, S., & Langrand, O.  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).  The extraordinary bite of crocodilians is a result of their anatomy. Like, head to head strength. The Nile crocodile on average has a bite force significantly stronger at 1250 psi more so than the Saltwater croc.  In comparison, lions, in the years from 1990 to 2006, were responsible for an estimated one-eighth as many fatal attacks on humans in Africa as were Nile crocodiles. In one case in the Tana River of Kenya, as observed by Max Fleishmann (communicated via letter to Theodore Roosevelt), a crocodile was able to bring down one of these huge herbivores by the help of muddy bank terrain, the adult female rhino's poor decision to enter deeper water rather than retreat to land and finally having been joined in drowning the animal by one to two other crocodiles. Nile crocodiles have green eyes. Most of the predators of eggs also opportunistically eat young crocodiles, including monitors and marabous, plus almost all co-existing raptorial birds, including vultures, eagles, and large owls and buzzards. Guggisberg (1972) saw multiple cases of predation on marabou storks (Leptoptilos crumenifer) and around Lake Turkana several may frequent heronries to pick off fledglings. Go further to know about it.  It is a rather common species of crocodile and is not endangered despite some regional declines or extinctions. Levels of lactic acid as high as they are in a crocodile would kill most vertebrates. 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! (1971). 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. You list the average size for the marine crocodile at 6.7 meters. They are apex predators, feeding on almost any living thing that they encounter. A 4.59 m (15.1 ft)-long saltwater crocodile has been confirmed as having the highest bite force ever recorded for an animal in a laboratory setting, with a bite force value of 16,414 N (3,690 lbf). In general, big cats and crocodiles have a relationship of mutual avoidance. They may also get the necessary leverage by lodging their prey under branches or stones, before rolling and ripping. I hope nobody believes this stuff… so far off on so many “facts”. The Nile croc, on the other hand tastes of hippo dung.  The hatchlings start to make a high-pitched chirping noise before hatching, which is the signal for the mother to rip open the nest. The ecology and physiology of the Nile crocodile.  Much prey taken is much smaller than the crocodile itself and such prey can be overpowered and swallowed with ease. , The Nile crocodile is presently the most common crocodilian in Africa, and is distributed throughout much of the continent. Most locals are well aware of how to behave in crocodile-occupied areas and some of the writings quoted by Guggisberg from the 19th and 20th century may require being taken with a "grain of salt". More modestly sized fish are generally swallowed whole. (1956). , At a reported incubation period of about 90 days, the stage is notably shorter than that of the American alligator (110–120 days) but slightly longer than that of the mugger crocodile. The “winners”—saltwater crocodiles—slammed their jaws shut with 3,700 pounds per square inch (psi), or 16,460 newtons, of bite force.  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. When groups are sharing a kill, they use each other for leverage, biting down hard and then twisting their bodies to tear off large pieces of meat in a "death roll".  In yet another historic crocodile stronghold, the Olifants River, which flows through Kruger National Park, numerous crocodile deaths have been reported. …Did you just make up all this shit one day or what?? It is known for its death roll, it grabs its prey and roll it powerful until prey died. Above, I have explained comparison between Nile crocodile vs Salt water crocodile. Thiollay, J. M. (1989). On other occasions, more of its head and upper body is visible, especially when the terrestrial prey animal is on higher ground, to get a sense of the direction of the prey item as the top of an embankment or on a tree branch.  The crocodile mainly hunts land animals by almost fully submerging its body under water. No chance. 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. 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. Adults can eat young Hippo, buffalos, zebras, hyenas, warthlogs, antelope, baboons, giraffe, wildebeest and big cats. 'On the internet you usually find pictures of buffalo, hippo, and lion fighting - but very rarely crocodiles.' , During the mating season, males attract females by bellowing, slapping their snouts in the water, blowing water out of their noses, and making a variety of other noises. 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. , Rodents and shrews may enter the diet of juvenile crocodiles, i.e. and Clarias gariepinus, which are preyed upon quite regularly in areas where they are common. Some variation occurs relative to environment; specimens from swift-flowing waters tend to be lighter in colour than those dwelling in murkier lakes or swamps, which provides camouflage that suits their environment, an example of clinal variation. On average, according to Cott (1961), female sexual maturity occurs when they reach 2.2 to 3 m (7 ft 3 in to 9 ft 10 in) in length.  However, mouth-gaping (while essential to thermoregulation) may also serve as a threat display to other crocodiles, for example when specimens have been observed mouth-gaping at night when overheating is not a risk. The saltwater crocodile is considered a sister taxon of the Siamese and the Nile crocodile. However, compared to the narrow-snouted, streamlined gharial and false gharial, the Nile crocodile is rather more robust and ranks second to the saltwater crocodile in total average body mass among living crocodilians and third among all living reptiles - the massive leatherback turtle (Dermochelys coriacea) has a mean body mass slightly less than that of an average mature male saltwater crocodiles. It swims with same speed as of dolphin. Plus, they would leave eachother alone- too much risk for injury for both animals. Compare Bull vs. Bear in Face to Face Fight. On top of that there would be many other deciding factors such as experience, previous injuries, and overall health.  Unsurprisingly, once exposed to the elements as hatchlings, the young, small Nile crocodiles are even more vulnerable. Miscellaneous examples of areas in the last few decades with a dozen or more fatal crocodile attacks annually include Korogwe District, Tanzania, Niassa Reserve, Mozambique and the area around Lower Zambezi National Park, Zambia. 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 … Still, it was difficult for someone to know who will win the fight. I noticed that they are in the same genus. If you are a betting man, put every shilling you have on the Killer Whale! It makes its prey off balance and making easier to drag the prey to water.  At the no-longer-existent Ripon Falls in Uganda, one adult male hippopotamus was seen to be badly injured in a mating battle with a rival bull hippo, and was then subsequently attacked by several crocodiles, causing it to retreat to a reedbed. The Saltwater crocodile is the largest living reptile, and a truly fearsome beast. I think the saltie wins because its a little bigger stronger meaner and has more powerful jaws, the only thing the nile has is that it has more thick skin than the saltie, the nile croc is more aggressive, it hunts bigger animals consistently, more muscular less fat, like comparing a lion with a tiger, a lion has the same advantages, little lighter but stronger more aggressive and territorial, don’t write back i know for a fact, Male crocs are territorial and fight. Nearly 70% of the crocodiles examined by Cott (1961) had some remains of snails inside their stomachs. Male Nile crocodiles are about 30 to 50 cm (12 to 20 in) longer on average at sexual maturity and grow more so than females after becoming sexually mature, especially expanding in bulk after exceeding 4 m (13 ft 1 in) in length. , Isolated populations also exist in Madagascar, which likely colonized the island after the extinction of voay. However, specimens exceeding 6.1 m (20 ft) in length and weighing up to 1,089 kg (2,400 lb) have been recorded.  It is thought to be either difficult or impossible for hatchlings to escape the nest burrow without assistance, as the surface may become very heavy and packed above them. 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. , 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. The species, however, also has small, oval osteoderms on the sides of the body, as well as the throat.  Groups of Nile crocodiles may travel hundreds of meters from a waterway to feast on a carcass. 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. They are thought to have become extinct in the Seychelles in the early 19th century (1810–1820). Who will win the fight between Nile Crocodile and Salt Water Crocodile? Osprey (.  However, Guggisberg (1972) had seen examples of birds picking scraps of meat from the teeth of basking crocodiles (without entering the mouth) and prey from soil very near basking crocodiles, so felt it was not impossible that a bold, hungry bird may occasionally nearly enter a crocodile's mouth, but not likely as a habitual behaviour. Saltwater Crocodiles also have the strongest bite of any animal alive today, with their bite force being similar to the estimated bite of T. rex. The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries.  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. In comparison, piscivorous water birds from Africa eat far more per day despite being a fraction of the body size of a crocodile, for example a cormorant eats up to 1.4 kg (3.1 lb) per day (about 70% of its own body weight), while a pelican consumes up to 3.1 kg (6.8 lb) per day (about 35% of its own weight). 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%). They are generalists, taking a variety of prey. Parental care in Crocodilia, with special reference to, Hancock, James A.; Kushlan, James Anthony and Kahl, M. Philip (1992). The two pieces of information the I have just cites were in your second paragraph. 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). Crocodiles tend to respect this order; when it is infringed, the results are often violent and sometimes fatal. The Saltwater crocodile average size is between 4 and 5 metres for an adult male this is also the average for a mile crocodile, the maximum size for a Saltwater crocodile is 6 metres and very occasionaly just over 7 metre but taken into account this is very rare but possible given the exact right available food and habitat in very remote areas far from human interference, generally Nile crocs max out at just over 5 metres with the exception like Gustave who is said to be 5.8 metres.
