== Running speeds ==
I think there are some issues with the paragraph “The zebra can reach a speed of 68.4 km/h (42.5 mph) compared to 57.6 km/h (35.8 mph) for the lion, but lions have a higher maximum acceleration” in the “Ecology and behaviour” section. 1) It seems ridiculous to me to give a speed down to a tenth of a km/h, given the difficulty in measuring speed, the terrain, the individual animal, the species of zebra etc. 2) If I click on the cited reference I can’t actually search the reference to back up the statement there. 3) The articles on Wikipedia cite different top speeds.
:https://en.wikipedia.org/wiki/Lion ... about 80 km/h 
:https://en.wikipedia.org/wiki/Plains_zebra ... about 60-70 km/h
I suggest altering the figures in the paragraph to match the other figures on Wikipedia. Bringing in @[[User:LittleJerry|LittleJerry]] who reverted this edit.

:: The precision is ridiculous. I've linked the page number in the {{tl|sfn}} template and combined the two sentences so it is now clear the one source gives maximum speeds, accelerations, and the conclusion about the 6 second window of opportunity for the lion. I've changed the numbers to 68 km/h (43 mph), i.e the best approximation of the source 19 m/s, and 58 km/h (36mph) for 16 m/s. I couldn't get the convert template to give the right numbers with right precision so removed them.
:: If the other articles have better sources for the speeds then they can be used instead, but now the text follows the source with sensible precision. —&nbsp;<span style="font-family:Arial;background:#d6ffe6;border:solid 1px;border-radius:5px;box-shadow:darkcyan 0px 1px 1px;">&nbsp;[[User:Jts1882|Jts1882]]&nbsp;&#124;[[User talk:Jts1882|&nbsp;talk]]&nbsp;</span> 14:13, 28 March 2022 (UTC)
:::Thanks for that Jts1882! The only issue I still have is the figure for the lion's top speed. Numerous articles on the Internet suggest a lion can run at about 50 mph (80 km/h), which is a lot more than the 36 mph (58 km/h) given in this article. (Example: https://www.britannica.com/list/the-fastest-animals-on-earth) [[User: BrightOrion|<b style="color:green">Bright</b><b style="color:blue">Orion</b>]] ([[User talk:BrightOrion|talk]]) 14:26, 28 March 2022 (UTC)
:::: Yes, I saw that, but just wanted to deal with the precision issue you rightly drew attention to. The conversions are as follows:
::::* Zebra speed: {{cvt|19|m/s|km/h}} and  {{cvt|19|m/s|mph}} (conversions using templates)
::::* Lion speed: {{cvt|16|m/s|km/h}} and  {{cvt|16|m/s|mph}} (ditto)
::::* {{cvt|68|km/h|mph}} (wrong mph)
::::* {{cvt|68.4|km/h|mph|0}} (wrong precision for km/hr; needs to round both)
::::* 19 m/s (68 km/h or 43 mph) and 16 m/s (58 km/h or 36 mph)  (preferred output; can a template do this?)
:::: I prefer the latter format, which gives the speed as given by the source (in m/s) and then shows the two conversions in parentheses.
:::: The best number for the top speed of the lion should definitely be given further consideration. —&nbsp;<span style="font-family:Arial;background:#d6ffe6;border:solid 1px;border-radius:5px;box-shadow:darkcyan 0px 1px 1px;">&nbsp;[[User:Jts1882|Jts1882]]&nbsp;&#124;[[User talk:Jts1882|&nbsp;talk]]&nbsp;</span> 14:50, 28 March 2022 (UTC)

::::::: Have you tried the [https://wikipedialibrary.wmflabs.org/users/my_library/ Wikipedia Library]?
::::::: If you look at the beginning of the results (p216) it says:
:::::::{{tqb|In the hunting sequence, analyzed in this study, the lion attained a lower running speed (10.4ms-1) than in the multiple hunting sequences (13.5ms-1) analyzed by Elliott et al. (1977; fig. 5), which involved pursuit of wildebeest (the same prey species as in this study), as well as zebra ''Equus burchelli'' and Thomson’s gazelle. This could have been due to the predator not having singled out a particular prey individual during the filmed portion of the hunting sequence. Indeed, the hunt appears to have been unsuccessful.}}
::::::: This suggests not all measurements are equal and that the highest speeds will only be achieve under true hunting conditions. The Elliott number seems reasonably compatible with the slightly higher 16m/s currently quoted. —&nbsp;<span style="font-family:Arial;background:#d6ffe6;border:solid 1px;border-radius:5px;box-shadow:darkcyan 0px 1px 1px;">&nbsp;[[User:Jts1882|Jts1882]]&nbsp;&#124;[[User talk:Jts1882|&nbsp;talk]]&nbsp;</span> 10:56, 29 March 2022 (UTC)

::::::::Yes, the figure of 13.5ms-1 is quite close to the 16ms-1 mentioned in this Zebra article.
::::::::Of course, there may be other studies showing lions running faster than this. I'll do some more searching. [[User: BrightOrion|<b style="color:green">Bright</b><b style="color:blue">Orion</b>]] ([[User talk:BrightOrion|talk]]) 11:03, 29 March 2022 (UTC)
:::::::::Sorry this discussion is getting so long. I found another academic paper called "Biomechanics of predator–prey arms race in lion, zebra, cheetah and impala". If anyone can access it, please post the data for lion speed here. Thanks. The video of that paper says lions are faster than zebras (at the 1:38 mark) https://www.youtube.com/watch?v=UVRkmPfkECE&t=98s [[User: BrightOrion|<b style="color:green">Bright</b><b style="color:blue">Orion</b>]] ([[User talk:BrightOrion|talk]]) 12:27, 29 March 2022 (UTC)
::::::::::: This is the purpose of talk pages. To decide on what information to include.
::::::::::: The paper is available as [https://rvc-repository.worktribe.com/preview/1388812/11143.pdf pdf here]
::::::::::: {{tqb|The 98th percentile of speed was C - 19.9, I - 13.8, L - 13.9 and Z - 10.6 ms-1 which is 84, 78, 67 and 77% of the maximum achieved by three individuals which were C - 23.8, I - 17.7, L - 20.6 and Z - 13.8ms-1. So predators were faster than their prey and all species rarely approached their maximum recorded speed (Extended Data Fig. 5).}}
::::::::::: These numbers look good, although I'm not sure how to present it. The 98% percentile speed is a good measure to make the comparison, but the data shows the lion can exceed 20m/s in some cases. So a statement along the lines of the lion can reach 20m/s during a chase would be accurate, but isn't something explicitly stated in the source. —&nbsp;<span style="font-family:Arial;background:#d6ffe6;border:solid 1px;border-radius:5px;box-shadow:darkcyan 0px 1px 1px;">&nbsp;[[User:Jts1882|Jts1882]]&nbsp;&#124;[[User talk:Jts1882|&nbsp;talk]]&nbsp;</span> 13:05, 29 March 2022 (UTC)

:Hi LittleJerry, this issue relates to the paragraph in this article (Zebra article): "The zebra can reach a speed of 19 m/s (68 km/h; 43 mph) compared to 16 m/s (58 km/h; 36 mph) for the lion, but lions have almost twice the maximum acceleration, so a lion has to surprise a zebra within the first six seconds of breaking cover."

:::::When talking about the speed of an animal, we should talk about the speed of the fastest individual, right?
:::::So, I think we should use the figures of 20.6 ms-1 (46 mph) for the lion and 13.8 ms-1 (about 31 mph) for the zebra. But I'm ''still'' not convinced by this.

::::::: Yes, being used many times on the web says little about reliability. They often all just repeat a single source, which may or may not be reliable. It can also be taken from Wikipedia.
::::::: The [[Zebra]] article currently says 19 m/s (68 km/h; 43 mph) for the zebra and 16 m/s (58 km/h; 36 mph) for the lion following Caro, who references Garland 1983. I've found the [https://www.semanticscholar.org/paper/The-relation-between-maximal-running-speed-and-body-Garland/d50bec8bfb162ca0e08f1f6a04572247eafbe5ed Garland 1983 reference] and it uses {{cvt|64.0|km/h|m/s mph}} for the zebra. So it looks like the Caro book is a conversion (to m/s) and an inaccurate one at that (19 instead of 18m/s). Garland also says the methodology of the estimate is unknown and cites Bourliere (1964), a general book on mammals. The Garland estimate for the lion (59km/h) cites another book (Schaller, 1972) and lists the method as "subjective estimate". Another recent paper ([https://www-jstor-org.wikipedialibrary.idm.oclc.org/stable/24032751?searchText=EVOLUTION+OF+SPRINT+SPEED+IN+AFRICAN+SAVANNAH+HERBIVORES+IN+RELATION+TO+PREDATION&searchUri=%2Faction%2FdoBasicSearch%3FQuery%3DEVOLUTION%2BOF%2BSPRINT%2BSPEED%2BIN%2BAFRICAN%2BSAVANNAH%2BHERBIVORES%2BIN%2BRELATION%2BTO%2BPREDATION%2B%26so%3Drel&ab_segments=0%2FSYC-6292%2Ftest_segment_2&refreqid=fastly-default%3A6c2dd740550f7cc4b16f342085090d4a&seq=4 Bro-Jørgensen, 2013]) also uses 59km/h for the lion, citing [https://link.springer.com/article/10.1007/BF01041590 Janis and Wilhelm, 1993], who also use Garland (1983). I'm not convinced by that any of these estimates are based on rigorous scientific studies.

::::::::: There are two potential problems there:
:::::::::* While I agree with your statement, we need a source to say the maximum speed reliably recorded is 13.8m/s. That is our conclusion about one study. Similarly its not for us to decide what is anecdotal evidence. We need a source saying it.
:::::::::* The Wilson et al (2018) makes estimates of speed using the 98 percentile value. They also mention a maximum speed. One must be wary of using extreme values from a data set as they could be statistical outliers. They say this maximum speed is "the maximum achieved by three individuals". If this means its the average of the fastest measurement by three individuals then it might be acceptable, but it might be better to say some individuals reached speeds of about 20m/s.

:It's probably a good thing I'm not a professor, because I would hard fail any undergraduate paper, from freshman year up, that advanced the argument in that paper. 
:In mammalian biology, with a few notorious exceptions that cast the birds among the beasts, all of our cells contain all of our genes. It's not so different than the original security model of [[MS-DOS]] (aka none whatsoever) where all programs could access all memory. Species can go through phases where the regulatory system suppresses a gene globally (in the long term, a totally inactive gene will tend to degrade), but that vestigial gene can spring back to life again as the environment changes, in whole or in part. 
:So the argument from that paper above boils down to this: if the "default" is that every gene is turned on everywhere and always, then zebras are innately black. But there's no such default in mammalian biology. Most genes are turned off in most tissues most of the time, or we'd have sperm cells with hairy eyeballs. 
:A thick and contingent tapestry of suppression and activation is the only way this symphony has ever carried a tune, except as filmed by [[David Cronenberg]]. 
:The argument above is also ''[ed: close to]'' parallel to the argument that any human with XY chromosomes is inherently male, regardless of whether the special sauce in the Y chromosome is suitably activated (when it isn't, such a person typically becomes hyper-feminized). Yikes. Men have been nailed to crosses and then buried in stone crypts for suggesting less contentious perspectives on human nature. &mdash; [[user:MaxEnt|MaxEnt]] 22:40, 16 August 2022 (UTC)

== Use the same non-metric unit for height on all 3 species ==

In the table of extant species, Grévy's zebra is listed with a shoulder height of 4.10–5.25 ft.  The other two species are listed with their non-metric heights in inches (43–57 and 46–57 for the plains and mountain zebras, respectively).

Recommend changing Grévy's imperial unit height to 49–63 in to match the other two.  It'd also internally match the other non-metric measurements for body & tail length.  Finally, listing shoulder heights in inches is an easy conversion to HH (yes, hh is supposed to be for the withers).

== Sleep of zebra ==

I found misinformation in the passage "Zebras sleep for seven hours a day, standing up during the day and lying down during the night. They regularly use various objects as rubbing posts and will roll on the ground." - in the "Behaviour and ecology" section. 

As a source of this information there is provided Estes, R. (1991). The Behavior Guide to African Mammals, but I cannot see any information of sleep length in Zebras in this book. In fact I cannot find any source that would give this info. However I know plenty of credible resources that indicate, that zebras sleep about 2 hours per day, e.g. in "Siegel J. M. (2005). Clues to the functions of mammalian sleep. Nature, 437(7063), 1264–1271. https://doi.org/10.1038/nature04285" we can see that similar herbivores (like horses and donkeys) sleep only 2-3 hours per day. Info about short zebra sleep is also present in well-known handbooks like Pinel, J. P., & Barnes, S. J. (2021). Biopsychology.
