nile crocodile interesting facts

[14] Most observed fishing by crocodiles takes place in waters less than 1.5 m (4 ft 11 in) deep and fish are often caught when they swim into contact with the crocodile's head, even literally right into the reptile's mouth. [85], Larger fish, like catfish and freshwater bass, are preferred by adults more than 2.2 m (7 ft 3 in) in length.

[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. Retrieved on 2013-04-25. Per Guggisberg, this disregard (essentially regarding the crocodile as a lowly creature and thus non-threatening to humans) may account for the seemingly higher frequency of deadly attacks by crocodiles than by large mammalian carnivores. Learn how your comment data is processed. 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. [43] 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. [3][42] 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. The diet of the Nile crocodile is mainly fish, but it will attack almost anything unfortunate enough to cross its path, including zebras, small hippos, porcupines, birds, and other crocodiles.

On each side of the mouth, five teeth are in the front of the upper jaw (premaxilla), 13 or 14 are in the rest of the upper jaw (maxilla), and 14 or 15 are on either side of the lower jaw (mandible). [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. A crocodile's bite is the strongest bite of any animal in the world. [51] The diet of young crocodiles is made up largely of insects and other invertebrates, since this is the only prey the same animals can easily take.

[7][96] Primates of various sizes may be taken by subadult or adult crocodiles. [82][83], After Nile crocodiles reach 2 m (6 ft 7 in), the significance of most invertebrates in the diet decreases precipitously. They can apply high levels of force for extended periods of time, a great advantage for holding down large prey underwater to drown.[7].

When you think reptile, you think long, slithering, deadly creatures however not all reptiles align with this image. [7][49], For the crocodile inhabiting west and northwest Africa, see, Natural mortality of young Nile crocodiles. Cott, H.B. The crocodile reaches the maximum size of 4.5 to 5.5 m (14 ft 9 in to 18 ft 1 in) but adult males average 3.3 to 5 m (10 ft 10 in to 16 ft 5 in) and weigh as much as 150 to 700 kg (330 to 1,540 lb). While Egyptians worshipped crocodiles in the ancient times, people in India continue to worship crocodiles even today. [73], Nile crocodiles have been widely known to have gastroliths in their stomachs, which are stones swallowed by animals for various purposes. 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). Many such mummified crocodiles have been discovered by archaeologists in the present day. 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. [7][150] 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. If they were multiplying, it would mean that the waters in Florida could turn dangerous for humans.

[3][7][27] 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.

They were highly pampered and when they died, they were embalmed, mummified, and then buried in sacred tombs. Each year it is estimated that between 100 and 200 people are killed by these reptiles. [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. They also scavenge or steal kills from other predators, such as lions and leopards (Panthera pardus). 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. The crocodile population in this area is much more sparse, and has not been adequately surveyed. [20] The separation of the two is not recognized by the IUCN as their last evaluations of the group was in 2008 and 2009,[1][21] years before the primary publications supporting the distinction of the West African crocodiles. [7] The colouration also helps to camouflage it; juveniles are grey, multicoloured, or brown, with dark cross-bands on the tail and body.
