== Maximum size ==
Due to wikipedia as a source the largest confirmed Nile Crocodile (6.45 m.) is longer than the largest confirmed Saltwater Crocodile wich was hardly longer than 6.3 m. --[[User:Draco ignoramus sophomoricus|Draco ignoramus sophomoricus]] ([[User talk:Draco ignoramus sophomoricus|talk]]) 21:20, 3 June 2008 (UTC)
:"Due to Wikipedia as source"? What does that mean? The source listed in the article is this: "Wood, The Guinness Book of Animal Facts and Feats. Sterling Pub Co Inc (1983), {{ISBN|978-0851122359}} ". [[User:Funkynusayri|Funkynusayri]] ([[User talk:Funkynusayri|talk]]) 21:34, 3 June 2008 (UTC)


== Etymology ==
: It would be good to document what evidence Guinness based this on as it is pretty controversial - with the Salty being the generally accepted as the larger species - if the largest confirmed specimen does belong to the Nile then this is worth outlining. The Salty article does seem a lot more conservative about claims of size than this article is - for example Gustav being reported as 20-30' long - which is a huge range of possibilities - mentioning that he has been reported as being up to more than 9 metres long without comment on how likely this is may be a bit misleading. [[User:Djambalawa|Djambalawa]]


I think this etymology is incorrect and should be changed. The word "crocodile" and romance language equivalents is very old and certainly predates binomial nomenclature. The most parsimonious explanation for the genus name "Crocodylus" is that it was already the Latin word for crocodile. The Online Etymology Dictionary says the word can be traced back to Greek, but origins within Greek are unknown unless you accept Herodotus as a source.

~you don't want me too insult you yet you think you can call me names like that and not expect a negative response now how does that work and based on what I have seen on the anaconda disscussion page I think it is safe to say that out of both of us I'm not the idiot here. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/67.83.100.52|67.83.100.52]] ([[User talk:67.83.100.52|talk]]) 20:28, 8 January 2011 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

== Removal of following section ==
"However, adults also have enemies. Rock pythons, hippos, lions and leopards, and rhinos occassionally prey on adult nile crocodiles. The adult nile crocodile's biggest enemie is the rock python. The rock python coils around the crocodile and kills it, than swallows it whole. "
I find this highly suspect and removed due to lack of references. First off, rock pythons can take young crocs but I can't imagine it's even physically possible that an adult nile crocodile could be eaten by a python. Leopards are way too small to threaten an adult crocodile, and I've never even heard of an interaction between this water-avoiding cat and water-loving reptile. Hippos and rhinos are herbivores, although hippos may kill crocs out of aggression. Adult crocodiles may be preyed on by lions.

The King of Africa's Killers

The Nile crocodile is such a monstrous and aggressive creature that they have been known to attack adult elephants but not in the way you would think. They will wait for an elephant to come drink then lunge out and bite the trunk and the bite is so powerful that it can break the trunk and this can end up killing or making life harder for the elephant since the trunk is the primary part of an elephant's body that it uses for getting food and water. Now a Nile crocodile 21 feet long weighing 2,400 pounds will slaughter lions, leopards,young or even occasionally teenage or sometimes adult hippos. If a Giraffe came to the water to drink it could probably break it's neck with it's bite. The only threat to a 21 foot 2,400 pound behemoth is a hunter with a big rifle or machine gun. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/67.83.100.52|67.83.100.52]] ([[User talk:67.83.100.52|talk]]) 01:59, 7 November 2009 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->
:Nope. Hippos regularly kill adult crocodiles. Please cite sources in your TP arguments.[[Special:Contributions/50.111.55.122|50.111.55.122]] ([[User talk:50.111.55.122|talk]]) 16:37, 8 June 2018 (UTC)

== Diet ==

Ok, here is the general idea. I compiled information scattered around in the whole section into two solid paragraphs of good sourced material with only minor rechecks of previous versions. If you look at 2008 edits, mentions such as separate hunting habitats have been partially removed, whereas this is the key idea here.

Two subsequent paragraphs contain unsourced text and blah about how they hunt. Unless this was written by residents of Kenya, we actually need proof. People see it as unproductive edits because the rest is just bias, so maybe elaborate there. But ummm can we please NOT have undos a/p one person trying to improve the whole article without reaching consensus meeting with same person from the other side? If you don't like what I did, discuss it here BEFORE reverting, and not vice versa, because maybe others will come and improve it.

Or give it at the very least 24 hours. I'd really appreciate that. [[User:Shadiac|Shadiac]] ([[User talk:Shadiac|talk]]) 05:46, 19 March 2010 (UTC)

== Carnivore? ==

Shouldn't it be said SOMEWHERE in the article that this animal is a carnivore?--[[User:Michaelphillipr|Michaelphillipr]] ([[User talk:Michaelphillipr|talk]]) 12:20, 24 April 2010 (UTC)

== What I have heard ==

i heard on tv maybe a few years ago that the nile crocodile is nearly extinct. what i heard is that there wasnt enough of them left for the species to survive. <span style="font-size: smaller;" class="autosigned">—Preceding [[Wikipedia:Signatures|unsigned]] comment added by [[Special:Contributions/84.208.75.209|84.208.75.209]] ([[User talk:84.208.75.209|talk]]) 20:15, 24 July 2010 (UTC)</span><!-- Template:UnsignedIP --> <!--Autosigned by SineBot-->

== Endangered Status ==

Pretty sure that crocs aren't least concern, and somebody forgot to capatalize the LC, so it was probably an intended mess-up. Someone please correct it? I can't because Im no expert on crocs. xP.

==Fix case==

I've changed ''Nile Crocodile'' to ''Nile crocodile'' at several places in this article. There seemed no consistency. Please, if you decide to revert, do it selectively, some of them are arguable but others are ridiculous. [[User:Andrewa|Andrewa]] ([[User talk:Andrewa|talk]]) 23:57, 22 April 2011 (UTC)


==Desert Crocodiles==

Here is the complete study that a Spanish team carried on in 2008 http://www.plosone.org/article/info:doi%2F10.1371%2Fjournal.pone.0014734 They unveiled the conditions of Saharan crocodiles attesting that they aren't extinct yet, at least in some parts of the desert.

:Not only is it two, what we've been calling the "Nile crocodile" is [[paraphyly|paraphyletic]]!

== Regarding sizes of extant crocodilians ==

Recently, there has been a disagreement on the sizes of extant crocodilians and how the scientific community classifies this data and publishes them. It concerns this article as well, as I see some users are reverting edits, purely with good intensions (goodwill edits). However as these edits are inconsistent and etymologically incorrect, they are harming the article(s). I have listed some crucial points taking one user's edits as a starting point. It is on [[Talk:Saltwater crocodile]], please read carefully before reverting edits on this subject matter. [[User:Berkserker|Berkserker]] ([[User talk:Berkserker|talk]]) 04:35, 22 May 2016 (UTC)
:[[User:WelcometoJurassicPark]] listen carefully. First of all you need to learn to respect other people. Second you don't know if I'm a scientist or not. Third, what I said has nothing to do with me being a scientist, my discussion was about the already existing information and data excepted by herpetology. If you can't comprehend the discussion this isn't my problem, if you keep vandalising these pages, you will be blocked. Even though I saw your talk page full of vandalism complaints, in my discussion I had respectfully stated your reverts as good faith edits, now you are making it clear it was vandalism. [[User:Berkserker|Berkserker]] ([[User talk:Berkserker|talk]]) 05:01, 24 May 2016 (UTC)
::I missed one point, you claim it is "my opinion" that the given species weighs this much, however all are from published work of scientists, unlike your claim in which you say a single Guinness record of a single animal holds true for the weight/length ratio for the entire species (you at least need a sample size of 40...). Plus it was you to claim species A weighs more than species B without backing these claims. In the following paper already presented in the article (which you needed to read before reverting, but you didn't), you will see the C. porosus and C. niloticus have similar length/weight ratios, even though the author notes that the ratio of Lake Rudolf crocodiles with and empty stomach was far higher compared to populations elsewhere, hinting to a lower weight/length ratio, as the habitat suitability and prey availability is inferior to other habitats occupied by other populations. A similar study was made in Australia following new laws prohibiting hunting of saltwater crocodiles in the 80s (See Webb and Manolis (1989)). Despite the habitat and prey availability issue, you will see that weight/length ratio is very similar to that of C. porosus. According to the regression analysis on the article (Graham, A. D. (1968). The Lake Rudolf Crocodile (Crocodylus niloticus Laurenti) Population. Masters of Science Thesis, The University of East Africa.), you will see 4.5 meters corresponds to slightly over 400kg, 5 meters corresponds to slightly under 600 kg (compared to the 4.8 meter individual weighed at 680 kg by Graham and Beard (1973), from another habitat/population - more than 25% difference in body weight to length ratio), and 6-6.1 meters corresponds to 1000 kg, according to the Lake Rudolf sample. This puts the 6.45 m. individual shot in Tanzania either at a starving state, loss of blood after being shot or it shows the people measuring the animal made an error, possibly measuring over curves (I didn't read anywhere it was measured accurately by scientists, which you claim), or a combination of these reasons. [[User:Berkserker|Berkserker]] ([[User talk:Berkserker|talk]]) 06:20, 24 May 2016 (UTC)
You can also find a bunch of reliable sources saying that 20 ft (6.1 m) Nile crocodiles usually weigh about 2000 lb (910 kg), and saying that Nile crocodiles are proportionally lighter than Saltwater crocodiles (so lighter at the same length, or even if they are slightly longer), and why are you just talk about that 5 meters corresponds to slightly under 600 kg, compared to the 4.8 meter individual weighed at 680 kg by Graham and Beard (1973), from another habitat/population - more than 25% difference in body weight to length ratio, the opposite can happen, too (so it can be more than 25% lower than expected, too), and you don't have sources for being at a starving state, loss of blood of for a measirung error, but I let you be in the way you want, because I don't wanna be blocked. [[User:WelcometoJurassicPark]] ([[User talk:WelcometoJurassicPark|talk]]) 10:37, 24 May 2016 (UTC)
:It isn't really about how I want to be or not. I'm just putting together the best evidence to present the most accurate information for the good of the article. It isn't my goal to get you blocked either, you know how subtle and polite I approached your discussions, in order not to offend you, until I was offended myself that is. My point is, a single specimen can not be taken reference for an entire species' weight/length ratio. This is why I advised to use the data for this specimen only.

== Humans in 'Hunting and diet' Section? ==

Given the Nile Croc's extensive predation of humans, would it not make sense to list them among its prey in the appropriate section under the 'Mammals' sub-heading under 'Hunting and diet'?[[User:Sɑk pʰʌpəʔ|Sɑk pʰʌpəʔ]] ([[User talk:Sɑk pʰʌpəʔ|talk]]) 02:17, 15 December 2016 (UTC)

:No, we're just biased in that we notice when humans are eaten, but now wildebeest or fish. Even if you restrict to adult crocs, the fraction of calories the total crocodile population acquires from humans is insignificant. [[User:HCA|HCA]] ([[User talk:HCA|talk]]) 16:48, 15 December 2016 (UTC)

::The same is likely true of the Saltwater Crocodile, but there (https://en.wikipedia.org/wiki/Saltwater_crocodile#Hunting_and_diet) humans are listed as prey under the 'Hunting and diet' section.[[User:Sɑk pʰʌpəʔ|Sɑk pʰʌpəʔ]] ([[User talk:Sɑk pʰʌpəʔ|talk]]) 14:18, 14 October 2017 (UTC)

== Deaths ==

The Nile Crocodile is considered to be one of the most dangerous reptiles in the world and is responsible for nearly to over 1,000 deaths in Africa every year. One study posited the number of attacks by Nile crocodiles per year as 275 to 745, of which 63% are known to be fatal.
Because these reptiles live in close proximity to humans, attacks are frequent which can lead to more possible fatal attacks. [[User:Mariofan 520|Mariofan 520]] ([[User talk:Mariofan 520|talk]]) 02:17, 13 December 2018 (UTC)
:Yes, we can read the article too. What's your purpose in copying chunks of it to the talkpage? [[User:Meters|Meters]] ([[User talk:Meters|talk]]) 07:10, 13 December 2018 (UTC)

== Miocene fossil record? ==

While many of the fossil specimens assigned to the nile crocodile come from the Quarternary, these papers imply that fossil Nile crocodiles have been found as far back as the Miocene. https://www.nature.com/articles/nature00880, https://www.nature.com/articles/318173a0--[[User:Bubblesorg|Bubblesorg]] ([[User talk:Bubblesorg|talk]]) 20:01, 20 July 2020 (UTC)
