Talk:Nile crocodile

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. —Preceding unsigned comment added by 84.208.75.209 (talk) 20:15, 24 July 2010 (UTC)

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. 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.

Split with C. suchus

Something to keep an eye on and at least mention in the article: http://blogs.discovermagazine.com/notrocketscience/2011/09/14/nile-crocodile-is-actually-two-species-and-the-egyptians-knew-it/

Not only is it two, what we've been calling the "Nile crocodile" is paraphyletic! I've made the split; there's still more to put into the Desert Crocodile article as I haven't finished reading the paper yet. Bob the WikipediaN ^{(talk • contribs)} 06:07, 16 September 2011 (UTC)

Range map is outdated

It was made in 2004, before the west African species was acknowledged as separate. FunkMonk (talk) 03:31, 7 January 2012 (UTC)

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. 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. 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. 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 (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'?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. 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.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. 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? 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--Bubblesorg (talk) 20:01, 20 July 2020 (UTC)
