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. [47][54] In Lake Kyoga and Lake Kwana, 73.1% of the crocodiles that did not have empty stomachs had fish in their stomachs. Frank, L., Hemson, G., Kushnir, H., & Packer, C. (January 2006). species Crocodylus niloticus Laurenti, 1768 - Nile Crocodile. [129] Few details are known about the dietary habits of Nile crocodiles living in Madagascar, although they are considered potential predators of several lemur species. The Nile crocodile is also widely distributed, with strong, documented populations in many countries in eastern and southern Africa, including Somalia, Ethiopia, Kenya, Zambia and Zimbabwe. [89][105] Elsewhere, the waterbuck appears to be the most significant mammalian prey for large adult crocodiles, such as in Uganda and Zambia (although due to more sporadic general ungulate populations in those countries, ungulates are less common as prey than in some other countries), as well as in Hluhluwe–iMfolozi Park, South Africa. Etiópico [9][33] Today, Nile crocodiles are widely found in, among others, Somalia, Ethiopia, Uganda, Kenya, Egypt, the Central African Republic, the Democratic Republic of the Congo, Equatorial Guinea, Tanzania, Rwanda, Burundi, Zambia, Zimbabwe, Gabon, Angola, South Africa, Malawi, Mozambique, Namibia, Sudan, South Sudan, Botswana, and Cameroon. [47][105] 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.[151].

Spatial distribution responses of the Nile Crocodile (Crocodylus [2][23] This species is farmed for its meat and leather in some parts of Africa. Crocodylidae (castellanizado como crocodílidos[ 1] o cocodrílidos[ 2] ) es una familia de saurópsidos, arcosaurios comúnmente conocidos como cocodrilos.

Chordata [9] A bull giraffe that lost his footing on a river bank in Kruger National Park was seen to be killed by a large crocodile, while in another case there, a healthy bull buffalo was seen to be overpowered and killed by an average-sized adult male crocodile measuring 4.25 m (13 ft 11 in) after a massive struggle, an incident less commonly seen at this size. The crocodile lunges its body out of water in practically the blink of an eye and grasps its prey. Crocodylus niloticus: Taxonomía: Cocodrilo del Nilo (Crocodylus niloticus) El Cocodrilo del Nilo (Crocodylus niloticus) fue registrado por Laurenti en 1768. [89][105][152] A 5 m (16 ft 5 in) specimen from Zambia was found to have eaten a "half-grown hippo". [34][37] The Nile crocodile shares with all crocodilians a nictitating membrane to protect the eyes and lachrymal glands to cleanse its eyes with tears. [20] 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. [5], 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. sunt Reptilium familia Crocodylos inter alia comprehendens. [9][33], Nile crocodiles usually dive for only a few minutes at a time, but can swim under water up to 30 minutes if threatened, and if they remain fully inactive, they can hold their breath for up to 2 hours (which, as aforementioned, is due to the high levels of lactic acid in their blood).

Mollusks may occasionally be taken by young crocodiles (they are taken in larger numbers later in life in parts of Uganda and Zambia). [5] Similarly, in Lake Baringo, the lungfish is the crocodile's main prey and the crocodile is the lungfish's primary predator. 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. Con la temporada de lluvias un montón de animales llegará a su hábitat para beber. Crocodylus: {gr, krokodeilos}, cocodrilo. Descriere. [8], Like all crocodiles, they are sexually dimorphic, with the males up to 30% larger than the females, though the difference is considerably less compared to some species, like the saltwater crocodile. Ha sido al mismo tiempo odiado y reverenciado por el hombre, especialmente en el Antiguo Egipto, donde los cocodrilos eran momificados y se les rendía culto. Predation on amuplariid water snails was especially heavy in Bangweulu Swamp, Lake Mweru Wantipa, and the Kafue Flats, where mollusks representing 89.1, 87, and 84.7% of all prey in these locations, respectively. Nile crocodiles normally crawl along on their bellies, but they can also "high walk" with their trunks raised above the ground. The arid land surrounding Lake Turkana is a relatively barren region for diverse or numerous prey other than fish, so fish are an exceptionally important food source to crocodiles there. [36] The Nile crocodile has fewer osteoderms on the belly, which are much more conspicuous on some of the more modestly sized crocodilians. No Confirmado In some areas, the mother crocodiles will only leave the nest if she needs to cool off (thermoregulation) by taking a quick dip or seeking out a patch of shade.

[48] 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. [71] 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 (i.e., excluding alligators and caimans), and does on occasion enter coastal and even marine waters. [62][63] In Madagascar, crocodiles occur in the western and southern parts from Sambirano to Tôlanaro. [96] In the Okavango Delta, the African pikes (Hepsetus spp.) [139], Other ungulates are taken by Nile crocodile more or less opportunistically.

[182] However, as is the case for many large animal species whether they are protected or not, persecution and poaching have continued apace and between the 1950s and 1980s, an estimated 3 million Nile crocodiles were slaughtered by humans for the leather trade. As it matures, Nile crocodiles become darker and the cross-bands fade, especially those on the upper-body. [9], Frogs are regionally significant prey for small, young crocodiles in many regions, mainly those in the 0.5 to 1.5 m (1 ft 8 in to 4 ft 11 in) size range. Aunque como especie no se encuentra en peligro de extinción, en algunos países la población de cocodrilos del Nilo corre un serio peligro de desaparecer a causa del terrible exterminio ocasionado por el hombre.En otros países esta en Preocupación menor, Yo Depredador - El Cocodrilo - HD ( Documental ), El contenido de la comunidad está disponible bajo. [17] 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.

[16] 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. [33] Pooley found in Royal Natal National Park that during aestivation, young crocodiles of 60 to 90 cm (24 to 35 in) total length would dig tunnels around 1.2 to 1.8 m (3 ft 11 in to 5 ft 11 in) in depth for most, some tunnels measuring more than 2.7 m (8 ft 10 in), the longest there being 3.65 m (12 ft 0 in). 1 Taxonomía Reino: Animalia Filo: Chordata Clase: Sauropsida Orden: Crocodilia Familia: Crocodylidae Subfamilia: Se encontró adentro – Página 2Crocodylus lloidi , a species known from the Tertiary and early Pleistocene of Africa is supposed to have been ancestral to the Nile crocodile .

Revisión de los patrones de distribución de Crocodylus niloticus Laurenti 1768, en Etiopía, y estima de tamaño corporal de grandes ejemplares del lado Chamo El cocodrilo de Thorbjarnarson (Crocodylus thorbjarnarsoni) fue una especie de cocodrilo que vivió en África desde el Plioceno hasta el Pleistoceno, bastante relacionada al Crocodylus anthropophagus de la misma época y perteneciente al mismo género que el los cocodrilos actuales. [196][197][198] Other wild animals responsible for more annual human mortalities either attack humans in self-defense, as do venomous snakes,[199] or are deadly only as vectors of disease or infection, such as snails,[200] rats[201] and mosquitos. [89][105] Small carnivores are readily taken opportunistically, including both African clawless otters (Aonyx capensis)[125] and spotted-necked otters (Hydrictis maculicollis),[9] as well as water mongoose (Atilax paludinosus),[5] African wildcats (Felis silvestris lybica)[5] and servals (Leptailurus serval). Carcass size shapes the structure and functioning of an African scavenging assemblage. Una especie, el cocodrilo marino (Crocodylus porosus), es el mayor de los cocodrilos de la actualidad (el más grande del que se tiene noticia medía 8,5 m y pesaba 1700 … Filo Although crocodiles occasionally prey on hippopotamus calves, even large adult crocodiles rarely attack them because of the aggressive defense by mother hippos and the close protection of the herd, which pose a serious threat. Type: Crocodylus niloticus. Download crocodylus niloticus stock photos. , 1768. [105] 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). 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. In addition, as an animal that feeds rarely, sometimes only a few times in a year, even the individual stomach content examinations sometimes prove to be unsuccessful. At this time of plenty (before irrigation operations by humans led St. Lucia to have dangerously high saline levels), a 2.5 m (8 ft 2 in) crocodile could expect to eat 1.1 kg (2.4 lb) of mullet daily, an exceptionally large daily amount for a crocodile. [5][9][33] Birds most often taken are African darters (Anhinga rufa) and reed (Microcarbo africanus) and white-breasted cormorants (Phalacrocorax lucidus), followed by various waterfowl, including most breeding geese and ducks in Africa. Sobek era representado como un cocodrilo, o como hombre con cabeza de cocodrilo, con la corona Atef. [85] 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. Crocodylus comes from the Greek word meaning lizard and niloticus means from the Nile River. Tomará aproximadamente 90 días antes de que los jóvenes cocodrilos comiencen a salir de los huevos. [5][90], Crabs are also largely taken by crocodiles under 1.5 m (4 ft 11 in), especially the genus Potamonautes, with different species being the primary crustacean food in different areas. Arachnids such as Dolomedes water spiders are taken, but always secondarily to insects in Uganda and Zambia. These have consisted of: C. n. africanus (informally named the East African Nile crocodile), C. n. chamses (the West African Nile crocodile), C. n. cowiei (the South African Nile crocodile), C. n. madagascariensis (the Malagasy or Madagascar Nile crocodile, regionally also known as the croco Mada, which translates to Malagasy crocodile), C. n. niloticus (the Ethiopian Nile crocodile, this would be the nominate subspecies), C. n. pauciscutatus (the Kenyan Nile crocodile) and C. (n.) suchus (now widely perceived by crocodilian biologists as a separate species). 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.) [19][21][22], Although originally thought to be the same species as the West African crocodile, genetic studies using DNA sequencing have revealed that the Nile crocodile is actually more closely related to the crocodiles of the Americas, namely the American (C. acutus), Cuban (C. rhombifer), Morelet's (C. moreletii), and Orinoco crocodiles (C. Nests have been recorded seldom in concealed positions such as under a bush or in grasses, but normally in open spots on the bank. [20], Females lay their eggs about one to two months after mating. Taxonomía La especie fue nombrada por Étienne Geoffroy Saint-Hilaire en 1807, al descubrir diferencias entre los cráneos de un cocodrilo momificado y los de C. niloticus . Crocodylidae (-arum, m.pl.) species Crocodylus porosus Schneider, 1801 - Estuarine Crocodile. These may include Grévy's (Equus grevyi)[140] and plains zebras (Equus quagga),[141] pygmy hippopotamus (Choeropsis liberiensis),[142] warthogs (Phacochoerus africanus),[9] bushpigs (Potamochoerus larvatus)[105] and red river hogs (Potamochoerus porcus). [133], Among the mammals, the bulk of the prey for adults is antelopes. [9] The species began to be hunted on a much larger scale from the 1940s to the 1960s, primarily for high-quality leather, although also for meat with its purported curative properties. 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.

When the male hippo returned to the water, it was drowned and killed by the group of crocodiles amid "a truly terrifying commotion". The Nile crocodile (Crocodylus niloticus) is a large crocodilian native to freshwater habitats in Africa, where it is present in 26 countries.Due to its widespread occurrence and stable population trend, it has been listed as Least Concern on the IUCN Red List since 1996. [5][47][55][56] This gives the Nile crocodile somewhat of a size advantage over the next largest non-marine predator on the African continent, the lion (Panthera leo), which averages 188 kg (414 lb) in males and 124 kg (273 lb) in females, and attains a maximum known weight of 313 kg (690 lb), far less than that of large male crocodiles. Ea sunt proximi avium cognati vivi. El cocodrilo del Nilo (Crocodylus niloticus) es una especie de saurópsido crocodilio de la familia Crocodylidae. Reino The Nile crocodile has historically been recorded in areas where they are now regionally extinct. [156] Most conflicts over food occur near the water and can literally lead to a tug-of-war over a carcass that can end either way, although seldom is there any serious fighting or bloodshed between the large carnivores. [20][188] Retraction of wetlands due both to direct habitat destruction by humans and environmental factor possibly related to global warming is perhaps linked to the extinction of Nile crocodiles in the last few centuries in Syria, Israel and Tunisia. [5][9][175], Conservation organizations have determined that the main threats to Nile crocodiles, in turn, are loss of habitat, pollution, hunting, and human activities such as accidental entanglement in fishing nets. [33] The crocodile mainly hunts land animals by almost fully submerging its body under water. Moleón, M., Sánchez‐Zapata, J. [9][159] At the end of the two years, the hatchlings will be about 1.2 m (3 ft 11 in) long, and will naturally depart the nest area, avoiding the territories of older and larger crocodiles. [12][54] Despite the attentive care of both parents, the nests are often raided by humans and monitor lizards or other animals while she is temporarily absent. La cabeza del Crocodylus acutuses estrecha y el hocico es largo, aspecto que lo diferencia de los caimanes. login. Se requieren campos marcados con un asterisco. SUMMARY: Three different reptilian species Psammophis sibilans (Order Ophidia), Tarentola annularis (Order Squamata and Crocodylus niloticus (Order Crocodylia) are used in the present study.Their tongue is removed and examined morphologically. El orden incluye a los cocodrilos (familia Crocodylidae), a los gaviales (familia Gavialidae) y a los aligátores y caimanes (familia Alligatoridae).Aunque a menudo se utiliza para referirse a todos ellos, de forma estricta el término 'cocodrilo' se refiere solo a los miembros de la familia Crocodylidae. [9][146], Particularly large adults, on occasion, take on even larger prey, such as giraffe (Giraffa camelopardalis),[105][147] Cape buffalo (Syncerus caffer),[105][147] and young African bush elephants (Loxodonta africana).

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. [5], 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. [9][150] An additional case of predation on an adult black rhino was reportedly observed in northern Zambia. Contrariamente, por ejemplo, con los caimanes, no construyen nidos, ni rudimentarios, pero los entierran en la arena de las riberas de los ríos o de los lagos donde viven. In crocodiles between these distributions egg-laying is in intermediate months, often focused between April and July. Once they reach their juvenile stage, very large African rock pythons and big cats remain as the only predatory threat to young crocodiles. Varanus niloticus. (2002).

[39][40] 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. 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),[121][154] African wild dogs, jackals,[89][105] and cheetahs (Acinonyx jubatus).

[23] Though the Nile crocodile has been hunted since ancient times,[181] the advent of the readily available firearm made it much easier to kill these potentially dangerous reptiles. [13], In studies preceding the slaughter of crocodiles for the leather trade, when there were believed to be many more Nile crocodiles, a roughly estimated 1,000 human fatalities per annum by Nile crocodiles were posited with a roughly equal number of aborted attacks.

Among crocodilians today, only the saltwater crocodile occurs over a broader geographic area,[59] although other species, especially the spectacled caiman (Caiman crocodilus) (due to its small size and extreme adaptability in habitat and flexibility in diet), seem to actually be more abundant. Dependiendo de donde viven, pueden incluir vacas, ovejas, e incluso jirafas. [196] 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. Once the eggs hatch, the female may lead the hatchlings to water, or even carry them there in her mouth, as female American alligators have been observed doing. [9][159] 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.
