nile crocodile vs saltwater crocodile bite force

[3] Specimens shot near Mpondwe on the Semliki River had gastroliths in their stomach despite being shot miles away from any sources for stones, the same applies to the Kafue Flats, Upper Zambesi and Bangweulu Swamp, all of which often had stones inside them despite being nowhere near stony regions. [36], 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). Once they reach their juvenile stage, very large African rock pythons and big cats remain as the only predatory threat to young crocodiles. [3], 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. [7] Crocodile teeth are not used for tearing up flesh, but to sink deep into it and hold on to the prey item. I have watched some documentaries in which Nile crocodile gets tired faster while saltwater crocodiles do death roll and any possible to get out of it. [18] In Lake Sibaya, South Africa, it was determined that in the 21st century, persecution continues as the direct cause for the inability of Nile crocodiles to recover after the leather trade last century. The saltwater crocodile is found in rivers and coastal areas of northern Australia, Papua New Guinea and Indonesia, as well as in southeast Asia. [124], Among the mammals, the bulk of the prey for adults is antelopes. If their jaws are bound together in the extreme midday heat, Nile crocodiles may easily die from overheating. The average size of the saltwater crocodile is 6.7 m and weight around 2000 Kg and females are smaller from males. [96] Other turtle species commonly recorded among Nile crocodile prey include the Speke's hinge-back tortoise (Kinixys spekii) and East African black mud turtle (Pelusios subniger). Does it honestly matter with size, strength, or weight? 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. More than half of the crocodiles observed by Cott (1961), if not disturbed, spent the hours from 9:00 am to 4:00 pm continuously basking with their jaws open if conditions were sunny. I actually think the biggest crocodiles are those found in the Mara river in Kenya. A saltwater crocodile does not have a stronger bite force than a Nile crocodile period. In the comparison under the 3rd picture you say, “Nile crocodile is heavier and has stronger bite force but when it is compare with salty crocodile then they both have similar jaw structure.” but on the chart you have the Nile with a 4 in force and the Salty has 5. 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. and by the way weight doesn’t matter. 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! [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. [156], When Nile crocodiles have been entirely free from disturbance in the past, they may nest gregariously with the nest lying so close together that after hatching time the rims of craters are almost contiguous. Most of what else u said is correct though. [153][154] Once a female has been attracted, the pair warble and rub the undersides of their jaws together. The range of this species once stretched northward throughout the Nile, as far north as the Nile delta. 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. [121][122] Other nonungulate prey known to be attacked by Nile crocodiles includes aardvarks (Orycteropus afer)[123] and African manatees (Trichechus senegalensis). [7][13][14], 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. 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. [7][49] The only aspect of mortality in this age range that is well studied is predation and this is most likely the primary cause of death while the saurians are still diminutive. Hippopotamus calves have been observed to at times act brazenly around crocodiles, foraging without apparent concern and even bumping into the reptiles. [3] 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. They found in eastern coast of India to south east Asia, Australia, Africa and Japan. In 1993, 80,000 Nile crocodile skins were produced, the majority from ranches in Zimbabwe and South Africa. 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). 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. Among the larger males of a population, territorial clashes can lead to physical fighting between males especially if they are near the same size. Agreed. Outside water, crocodiles can meet competition from other dominant savannah predators, notably big cats, which in Africa are represented by lions, cheetahs, and leopards. Although this clearly is a deliberate behaviour for the species, the purpose is not definitively known. Adamson, J. [73], Nile crocodiles have been widely known to have gastroliths in their stomachs, which are stones swallowed by animals for various purposes. Crocs do eat bull sharks all the time though. [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. I hope nobody believes this stuff… so far off on so many “facts”. [77] Much prey taken is much smaller than the crocodile itself and such prey can be overpowered and swallowed with ease. Sybney, I understand and had the same dilemma when I read the comparisons. This is why I hate the internet. For example, in Lake Turkana, Kenya, 48.4% of crocodiles had empty stomachs. 2 Saltwater Crocodile – Bite Force : 3690 psi. The Great White realized how it killed the Saltwater Crocodile, which was by biting it's soft underbelly. [3] Intimidation displays may also resolve these conflicts. Amongst salties you get huge variations in aggression, as with nile crocodiles. 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. 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). Your email address will not be published. Biggest and strongest will win. [8] They share basking spots and large food sources, such as schools of fish and big carcasses. The status of Nile crocodiles was variable based on the regional prosperity and extent of conserved wetlands by the 1970s. 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. 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 … [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. Good chance both die in the end. Gastropoda (4126 records per Cott) were taken much more than Lamellibranchiata (six records). [3][81] An exception to this is in Uganda and Zambia, where subadults and adults of even large sizes, up to 3.84 m (12 ft 7 in), may eat very large numbers of snails. 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. [43] In East Africa, they are found mostly in rivers, lakes, marshes, and dams, favoring open, broad bodies of water over smaller ones. [3] She finds a spot soft enough to allow her to dig a sideways slanted burrow. 2. [21] Though the Nile crocodile has been hunted since ancient times,[172] the advent of the readily available firearm made it much easier to kill these potentially dangerous reptiles. In some areas, some number of baboons is taken, such as in Okavango Delta, where chacma baboons (Papio ursinus) are eaten and Uganda, where olive baboons (Papio anubis) are taken. Sydney russel, he means force by strength. It covers widespread area of sub-saharan Africa and found in rivers, lakes and marshlands. Hypothetical. 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).
