Compare Bull vs. Bear in Face to Face Fight. In fact, probably much of the food from crocodile stomachs may come from scavenging carrion, and the crocodiles could be viewed as performing a similar function at times as do vultures or hyenas on land. Males can only be born if the temperature is within that narrow range. Breeding females along the Olifants were overall larger than those in Zimbabwe. The average estimated size of Nile crocodiles involved in fatal attacks is 3.5 m (11 ft 6 in). [3][7][115] Cape porcupines (Hystrix africaeaustralis) are known to have been preyed on several times in Kruger National Park, their quills apparently being an insufficient defense against the tough jaws and digestive systems of crocodiles. [49][150][152] In the Olifants River in South Africa, rainfall influenced the size of nesting females as only larger females (greater than 3 m (9 ft 10 in)) nested during the driest years. [187] 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. 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. Go further to know about it. Due to its widespread occurrence and stable population trend, it has been listed as Least Concern on the IUCN Red List since 1996. Moleón, M., Sánchez‐Zapata, J. Webb, and S.C. Manolis. It also sometimes referred to as the African crocodile, Ethiopian crocodile, common crocodile, or the black crocodile. [166] The single most virulent predator of nests is almost certainly the Nile monitor. [7][78] 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. [39] 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. [76] No matter where they attack prey, this and other crocodilians take practically all of their food by ambush, needing to grab their prey in a matter of seconds to succeed. 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. (2002). The population was severely depleted, and the species faced extinction. The hatchlings grow approximately that length each year for the first several years. NILE CROCODILE-For the Nile Crocodile in a same length it is slighty heavier than the Salty. Saltwater crocodile have more stamina under water and faster in comparison to Nile crocodile. [15] However, exertion by crocodilians can lead to death due to increasing lactic acid to lethal levels, which in turn leads to failure of the animal's internal organs. [21] 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. By contrast, you might tear into a steak with 150 to 200 psi (890 newtons). [3] Per Graham (1968), the average length and weight of a large sample of adult crocodiles from Lake Turkana (formerly known as Lake Rudolf), Kenya was 3.66 m (12 ft 0 in) and body mass of 201.6 kg (444 lb). Now I’ve always read that Salties are biggest crocodiles, so the biggest and healthiest of thesewin. If this happened? For example, a 3.9 m (12 ft 10 in) black caiman (Melanosuchus niger) was found to have a notably broader and heavier skull than that of a Nile crocodile measuring 4.8 m (15 ft 9 in). [99] Nile crocodiles apparently frequently station themselves underneath breeding colonies of darters and cormorants and presumably snatch up fledgling birds as they drop to the water before they can competently escape the saurian, as has been recorded with several other crocodilians. The status of Nile crocodiles was variable based on the regional prosperity and extent of conserved wetlands by the 1970s. [74] 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. [3] She finds a spot soft enough to allow her to dig a sideways slanted burrow. 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. Saltwater crocodile is known as Indo-Pacific crocodile, it is world largest living reptile which come under terrestrial as well as reptile category. Like all crocodilians, for example, the Nile crocodile is a quadruped with four short, splayed legs, a long, powerful tail, a scaly hide with rows of ossified scutes running down its back and tail, and powerful, elongated jaws. 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. [7] 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. [146], Living in the rich biosphere of Africa south of the Sahara, the Nile crocodile may come into contact with multiple other large predators. National Geographic documentary; "Bite Force", Brady Barr. 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. Above, I have explained comparison between Nile crocodile vs Salt water crocodile. [7], 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. [7][96] In some cases in Kruger National Park, antelope have been driven into water while being pursued by packs of African wild dogs (Lycaon pictus), which hunt by endurance, engaging prey in a grueling chase until it is exhausted (a very successful hunting style), only to be killed by opportunistic crocodiles. [148], On average, sexual maturity is obtained from 12 to 16 years of age. The nesting season can fall in nearly every month of the year. Arachnids such as Dolomedes water spiders are taken, but always secondarily to insects in Uganda and Zambia. [162] 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 comparison and difference between Nile crocodile vs Australian Salt water crocodile are given below. Never. I noticed that they are in the same genus. Höhnel Island (South Island) in Lake Rudolf. Occasionally, a crocodile quietly surfaces so that only its eyes (to check positioning) and nostrils are visible, and swims quietly and stealthily toward its mark. Cassell Illustrated, 978-0713723823. 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. Gastropoda (4126 records per Cott) were taken much more than Lamellibranchiata (six records). Sign up to receive ourPredators Face-Off's via email: Nile crocodile vs Salt water crocodile Comparison. 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. In order to handle, 16 foot salt crocodile, an average of 10 strong men are required. [2] Although capable of living in saline environments, this species is rarely found in saltwater, but occasionally inhabits deltas and brackish lakes. When crocodile nests are dug out and the young placed in water by the mother, in areas such as Royal Natal National Park predators can essentially enter a feeding frenzy. Most of what else u said is correct though. Have you actually seen the very biggest nile crocodiles in the Mara river in Kenya? [151] Crocodile 'protection programs' are artificial environments where crocodiles exist safely and without the threat of extermination from hunters. [116] The extraordinary bite of crocodilians is a result of their anatomy. Therefore, a male saltwater crocodile, which had attained a length around 4.59 m (15 ft 1 in), was found to have the most powerful biting force ever tested in a lab setting for any type of animal. They are not choosy for their diets. [13], Subadult and smaller adult Nile crocodiles use their bodies and tails to herd groups of fish toward a bank, and eat them with quick sideways jerks of their heads. Saltwater are more aggressive, more ego and usually more faster then Nile crocodiles. [1][21] This species is farmed for its meat and leather in some parts of Africa. Its place in the ecosystems it inhabits is largely unique, as it is the only large tetrapod carnivore that spends the majority of its life in water and hunting prey associated with aquatic zones. 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. Only the gharial (Gavialis gangeticus) (and perhaps some of the few very thin-snouted crocodilians) is likely to have noticeably diminished bite force compared to other living species due to its exceptionally narrow, fragile snout. However, for such large animals, their stomachs are relatively small, not much larger than a basketball in an average-sized adult, so as a rule, they are anything but voracious eaters. 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. [174] Recovery for the species appears quite gradual and few areas have recovered to bear crocodile populations, i.e. The Nile crocodile on average has a bite force significantly stronger at 1250 psi more so than the Saltwater croc. Lions rarely reach over 220kgs or anywhere close to 3 meters long. [92][93], When capturing large fish, they often drag the fish onto shore and swing their heads around to smash the fish onto the ground until it is dead or incapacitated. [27] They also feed on dead hippopotamuses (Hippopotamus amphibius) as a group (sometimes including three or four dozen crocodiles), tolerating each other. (1956). As pointed out earlier, you have conflicting and false information in your article. [3][7], 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. Killer whale has strongest bite force of any animal. The feeding ecology of yearling, juvenile and sub-adult Nile crocodiles, "FLMNH Ichthyology Department: Bull Shark", "Deadly bull shark is a magnificent, hunted creature | Florida Weekly", "Predator-prey relationships amongst the larger mammals of the Kruger National Park", "Persistent quacking in dabbling ducks: a predator-luring signal? (eds.). The enlarged fourth lower tooth fits into the notch on the upper jaw and is visible when the jaws are closed, as is the case with all true crocodiles. and ostriches (Struthio camelus), may be taken when they come to water to drink, but like most birds, are seldom harassed and a minor part of the diet. Nile crocodile isn’t heavier and not salty; nile crocodile is faster. [3][153] Nile crocodiles have temperature-dependent sex determination (TSD), which means the sex of their hatchlings is determined not by genetics as is the case in mammals and birds, but by the average temperature during the middle third of their incubation period. Nile crocodiles are relatively social crocodiles. 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. [117], Adult Nile crocodiles, i.e. 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. [7] 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. It makes its prey off balance and making easier to drag the prey to water. [27][29] 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. [10][150], 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. Adam man, I completely agree. The answer is a bite force value of 3,700 pounds for a 17-foot saltwater crocodile (as well as tooth pressures of 350,000 pounds per square inch).
