Talk:Great white shark

Edit request Add to information about the great white harvested on August 31,2011

He was released on October 25, off the coast of Santa Barbara by the aquarium's animal care staff. Based on the shark's behavior and condition prior to release, the Aquarium's white shark team had every confidence that he would do well back in the wild, and that the release would be a success. He appeared to be doing well before the release team lost sight of him as he swam away. However, according to data from an electronic tracking tag, he died soon afterward.

Incorrect Date for Great White Shark Caught Off Coast of Prince Edward Island

The year quoted in the article is 1988 but the correct year is 1983. http://www.jawshark.com/great_white_recorded_sizes.html, actually quotes two years in their article the first, and correct one, being 1983 and the second as 1988. Other sources: http://www.geerg.ca/shark_white.html http://new-brunswick.net/new-brunswick/sharks/species/greatwhite.html http://www.marinebiodiversity.ca/shark/english/facts.htm http://www.elasmo-research.org/publications/pdfs/COSEWIC%20Status%20Report%20on%20White%20Shark_April%202005.pdf http://publications.gc.ca/collections/Collection/CW69-14-507-2006E.pdf http://www.bookofeverything.com/website/docs/PEIBOE_NaturalWorld.pdf

All of the above sources cite 1983 as the correct year.Optimus past my Prime (talk) 21:31, 31 August 2012 (UTC)

Introduction

The last sentence is a complete non sequitor, Jaws never makes the argument or even really insinuates that humans are the preferred prey of great whites. — Preceding unsigned comment added by 98.218.249.191 (talk) 18:38, 19 December 2012 (UTC)

No, but it does insinuate that Great Whites actively hunt humans. douts (talk) 20:30, 19 December 2012 (UTC)

The cited source does not support the premise that Great Whites never actively hunt humans. In fact, it mentions 108 times that Great Whites attacked humans on the Pacific coast of the United States. No where in Jaws is it suggested that this is an ordinary Great White displaying typical behavior. — Preceding unsigned comment added by 98.218.249.191 (talk) 17:09, 5 February 2013 (UTC)

The issue with Jaws is that anyone with only basic general knowledge about great whites could be misled into believing that they actively hunt humans. In fact the film is one of the main reasons for the stigma around sharks in general which marine scientists are still trying to rectify. So the sentence about Jaws should defo stay in the article. douts (talk) 19:32, 5 February 2013 (UTC)

That would be fine if it was changed to say 'in reality, Great Whites have attacked humans 108 times on the Pacific coast of the United States' so that it actually reflects the cited source. — Preceding unsigned comment added by 98.218.249.191 (talk) 15:35, 5 March 2013 (UTC)

Lengths are quoted in metres to 3 digits precision when the source material only gives them (in feet) to 2 digits. The metric units should be rounded to have no greater precision (2 digits max.) than the original units had. Even better would be to reference a source in metres, since the units in feet are likely already approximate. (Indeed the reverse conversion back to feet also over-quotes precision: the source articles give lengths in feet, while the wikipedia article gives them in feet and inches). — Preceding unsigned comment added by 209.6.112.186 (talk) 12:41, 28 August 2016 (UTC)

583118755 (linked seemingly contradictory statements)

Erm, why would you link them, they were separate sentences and didn't contradict, it's perfectly possible for the shark most responsible for unprovoked attacks on humans to also not have humans as one of its preferred prey species, your edit has made them sound contradictory. If you just drop the and, you're probably ok, "shark,and of all shark species, the great white", or you can just revert. — Preceding unsigned comment added by 94.8.220.119 (talk) 18:52, 24 November 2013 (UTC)

"swam"

it should be "swam" here:

...a great white with a satellite tag was found to have immediately submerged to a depth of 500 m (1,600 ft) and swam to Hawaii.[59]  — Preceding unsigned comment added by 142.136.239.87 (talk) 22:44, 1 January 2014 (UTC) 

Opinion/Soapbox under "Reproduction"

The section on "Reproduction" closes with the following statement:

"If the Sea of Cortez is such a breeding ground, it is imperative that the area's laws be better enforced to ensure the survival of the breeding population."

This seems to me like opinion or advocacy (WP:NOTSOAPBOX). Would a more experienced editor care to comment? JeffBuckles (talk) 03:25, 7 January 2014 (UTC)

I agree. This sentence should be removed.

Citation needed in Conservation Status

The last paragraph under the Conservation Status heading seems suspect or superfluous without any citations.

"Fishermen target many sharks for their jaws, teeth, and fins, and as game fish in general. The great white shark, however, is rarely an object of commercial fishing, although its flesh is considered valuable. If casually captured (it happens for example in some tonnare in the Mediterranean), it is misleadingly sold as smooth-hound shark."

Who considers it valuable? What is the source that says it is sold as smooth-hound, or that it is rarely an object of commercial fishing?

Great white shark population

In a recent study in California, it has been found that there are over 2,400 white sharks off the coast of california, instead of the 2013 findings that there were only 340 sharks. Someone should edit the article to reflect the new findings as soon as possible.

Request to edit the following sentence

The great white shark is an apex predator of the seas and has no natural predators other than the Orca.[10]

While this sentence is quoting a book, the author clearly does not have an understanding of what the words "APEX PREDATOR" means as the author has contradicted the term "APEX PREDATOR" in the very sentence that he used the term.

Apex Predator = A predator with no natural predators.

The same sentence indicates that the Orca is in fact a natural predator of the Great White, thus excluding the Great White from the classification of "Apex Predator"

I suggest that the sentence be read worded to not copy the book author and instead say something like. "The great white shark is a top predator of the oceans who's only natural predator is the Orca." — Preceding unsigned comment added by Tws101 (talk • contribs) 02:21, 10 July 2014 (UTC)

Good point, correction made. JoelWhy?(talk) 14:23, 4 August 2014 (UTC)

The shark that was killed by orca in Farallon Islands in 1997 was an subadult only 10~13 feet long(). It should be noted that fish are animals that grow throughout their lifetime,and even between the adult great white sharks,the size differences can be astronomical. The average great white shark is around 15 feet long,which is far larger than the 10-foot shark eaten by killer whale. Some large free-swimming great white sharks are around 500~580cm(16.5~19 feet)(), and they are not uncommon.

The type of orca that eats sharks,on the other hand,is offshore killer whale,which are smaller than other killer whales in size,with less sexual dimorphism (). The group of orcas that ate the white shark in 1997 weren't offshore killer whale,but they,too,were very small in size compared to other types of killer whales. (The female that attacked the shark in 1997 was 4.7~5.2m in length) (

There are no records of great white sharks larger than its average size eaten by killer whales,and since large great whites attain sizes close to killer whales that eats sharks,the attacks are very unlikely. Also,as mentioned before,the shark that was killed by killer whale is one of the smallest adults,way behind the average size. My point is that great white sharks should not be excluded from the classification "apex predator,"and the sentence "The great white shark has no natural predators other than the orca." should be changed to,"Great white sharks have no natural predators,though small adults can fall prey to killer whales." It should be more specific. — Preceding unsigned comment added by Csw0219 (talk • contribs) 00:52, 22 January 2015 (UTC)

Age of Maturity

The introduction contains conflicting information on age of sexual maturity that should be resolved one way or the other. Looking at the source referenced for each fact, numbers 64 and 9, it seems to me that number 9 is superior though I would reference the source material for the article rather than the article itself. Here are the edits I propose, I would make it myself but cannot due to my unconfirmed status:

Introduction

"This shark reaches its maturity around 15 years of age and was previously believed to have a life span of over 30 years. The true lifespan of great white sharks is far longer; now estimated to be as long as 70 years or more, making it one of the longest lived cartilaginous fish currently known."

becomes

"This shark was previously believed to have a life span of approximately 30 years, but its true lifespan is now thought to be far longer at 70 years or more, which would make it one of the longest lived cartilaginous fish currently known."

I would remove references 8 and 9 from the introduction in accordance with the wishes of a previous editor since these references appear later in the article.

Ecology and behavior: Reproduction

"Great white sharks also reach sexual maturity at around 15 years of age."

becomes

"Great white sharks are currently believed to reach sexual maturity at ages 26 and 33 years for male and female sharks respectively." Reference here: http://www.publish.csiro.au/view/journals/dsp_journal_fulltext.cfm?nid=126&f=MF14127

I do not understand why the subject of lifespan is included under reproduction, but I will leave that to a more experienced editor to decide. I would make this minor edit regardless of where it should be:

"the true lifespan of the great white shark was revealed to be up to 70 years or more,"

becomes

"the true lifespan of the great white shark was revealed to be 70 years or more,"

Females breed every two to three years (Francis 1996; Compagno et al. 1997; Domeier 2012a). Although parturition (live birth) has never been observed, it is believed to occur in or near the warm waters of the SCB and northern Mexico in the late spring and summer."

Somebody fix it

THere is a section on Australia that says the sharks are protected. AND a bt earlier saying in Western Australia they are caught and killed as a matter of policy. THESE 2 bits are not clear together, expecilly to know if the latest polica in West Aust has changed the national / federal policy or if the sate is in breach of it somehow. Can someone that knows the situation beter makes these 2 bits clear?

Size

There is a debate between editors regarding the biggest great white shark ever measured. This article has been marked as a good article, and all of us have the responsibility to keep it that way. Therefore only publish confirmed and up to date information, while citing your findings. The two largest verified specimens that are currently accepted by official sources are the following.

- A 19.7 (or 19.8) footer caught off Western Australia , in 1984, and is accepted by shark expert J. E. Randall and later by José Castro from the National Oceanic and Atmospheric Association in the US

According to shark expert J. E. Randall, the largest white shark reliably measured was 6.0 m (19.7 ft), found near Ledge Point, Western Australia in 1987 (the shark was actually caught in 1984, but tooth measured and findings published by Randall in 1987). [hubpages.com/education/The--Biggest-Great-White-Shark-Ever-Found#] (hub pages is in general blocked so I couldn't provide the link, you need to copy and paste) “The largest white shark believed to have been measured reliably is a six-metre [19ft 8in] specimen from Ledge Point, Western Australia, caught on March 22 1984.” [1]

- A 20 footer caught off Canada's Prince Edward Island, in 1988, and is accepted by the Canadian Shark Research Center

According to the Canadian Shark Research Center, the world's largest accurately measured great white was 20 feet in length. This was a female caught in 1988 at Canada's Prince Edward Island. Local fisherman David McKendrick landed the toothy catch. Experts mainly agree that 20 feet is the more common maximum size for a great white, with these larger individuals weighing around 4,200 pounds. Females tend to be larger than males, so they can fall into the 20-footer group. The majority of great whites, however, measure between 13 and 16 feet with an average weight of 1,500 to 2,450 pounds. [2]

@WelcometoJurassicPark: As for the second 1945 Cuba specimen, you need to present your sources, otherwise there is only one specimen that is being discussed by officials and it has recently been proven to be much smaller. So I will be publishing these verified figures, if you have new and reliable sources please discuss. Berkserker (talk) 03:31, 3 June 2016 (UTC)

You can read in the soureces that there are two specimens. This one says 7000 lb (3175 kg): Echenique, E. J. "A Shark to Remember: The Story of a Great White Caught in 1945". while these says 3324 kg (7328 lb): https://ia800704.us.archive.org/21/items/cbarchive_109514_predatorybehaviourofthewhitesh1982/predatorybehaviourofthewhitesh1982.pdf http://www.bio-nica.info/biblioteca/Wroe2008GreatWhiteSharkBiteForce.pdf Two different figures, two different specimens. User:WelcometoJurassicPark (talk) 10:55, 03 June 2016 (UTC)

The Cojimar specimen has never been weighed, therefore the weight figure is just an estimate. No source I have read cites two separate specimens. These are basically different estimations of weight for the same specimen, that has been downsized in recent studies. I have cited two of the latest accepted max figures by 3 separate organisations. Did you know that even 11 meter specimens were accepted as legitimate and published as a maximum size for the white shark for decades? Scientific literature corrects its mistakes over time, therefore if there is a more recent study, proving the older one inaccurate, it is taken as principle. Therefore until the new analysis was present, all authors cited the Cojimar specimen. The sources you cited are written in the 80s, and a lot has changed since then. Plus you can see from the regression analysis on that article that it is an outlier. The cluster of max size is limited to 5.5-6 meters, and after a huge gap you see the Cojimar specimen. However authors at the time didn't question the data since it was accepted as legitimate at the time. You can see the same author mentioning the larger specimens once being accepted as legitimate, the exact thing has happened once again in the last couple of decades and the accepted size has changed once again. So the Cojimar specimen can only be mentioned on "Relationship with Humans" as a big fish tale. Berkserker (talk) 17:13, 3 June 2016 (UTC)

Note to all editors. I have taken out the unverified reports and organised them under a separate title. These could actually be completely removed in the long run, however for now placed them in a cultural context under relationship with humans. Berkserker (talk) 03:36, 4 June 2016 (UTC)

Edit request

In June 2018 the New Zealand Department of Conservation classified the great white shark under the New Zealand Threat Classification System as "Nationally Endangered". The species meets the criteria for this classification as there exists a moderate, stable population with a population of between 1000 to 5000 mature individuals. This classification has the qualifiers "Data Poor" and "Threatened Overseas".Ambrosia10 (talk) 16:50, 18 January 2019 (UTC)

Two attacks on live humpback whale off South Africa?

The two attacks sound very similar. Both involed live, engtangled humpbacks off South Africa, one off Port Elizabeth and another just off Mossel Bay. One whale was 23 ft (7 m) while the other was 33 ft (10 m). One involved two sharks the other one, but both involved sharks of 13 ft (4 m). They also both occurred at the same time of year but allegedly in different years, February 2017 vs February 2020. They also both involed attacks to the tail first and then to the head. Is this just a coincidence or do this involve the same attack? BulbousCow (talk) 04:52, 17 February 2021 (UTC)

Great White Sharks use magnetic fields in the ocean floor for navigation, but this page has no information, update needed by experts

I was watching PBS Nature show, I think it was this one, Sharks of Hawaii:

https://www.pbs.org/wnet/nature/about-sharks-hawaii/24807/

..and in the show I recall learning these things:

1. Sharks have sensors to detect magnetic fields 2. Ocean floors have many magnetic poles 3. Sharks have, in them, the map of these semi-permanent magnetic poles 4. Sharks can use the magnetic detector and the map to navigate the ocean

One piece of evidence, cited in the movie, is that sharks swim in near perfect straight lines to their destination, and; they do so at great depths so that the sun and stars are not of use for navigation, and; they stay straight even though there are dramatic currents that we expect would sweep them off course.

I am not an expert but I came here to learn more about this idea that the sharks have the compass and the map inside them and use it to swim straight for hundreds of miles of ocean.

The show Sharks of Hawaii is great. One shortcoming, in my opinion, but also lacking on this page, is the idea of putting trackers onto sharks. It seems to me that putting public tracking systems onto shark fins is going to reveal information to bad fishermen about where sharks cluster and where to find specific sharks. Maybe its okay but it struck me as extremely foolish and not good for the protection of great white sharks.

Aberrant Colouration (Albino, Leucistic & Piebald)

It has been stated in the article that Leucism is extremely rare in the species, quoting the beached baby in Australia. There are however two other records of different aberrant colouration in the literature for the Great white shark.

1. Albinism. A baby was caught on rod and reel in 1996 in South Africa, decribed as being white with red eyes. The specimen is in the possession of the South African Institute for Aquatic Biodiversity (SAIAB). Pictures of it can be found here: https://www.saiab.ac.za/saiabnews/iconic-specimen:-a-fish-of-a-life-time.htm. Source: Smale, M. J. and Heemstra, P. C. 1997. First record of albinism in the Great White Shark, Carcharodon carcharias (Linneaus, 1758). South African Journal of Science 93:243–245.

2. Leucism/Piebald. A juvenile was filmed alive in the Aegean Sea in 2020 near Turkey. The white colouration extended in a broad area from the undersite up the flanks to just below the first dorsal fin, which also showed a broad white posterior margin. The rest of the body was coloured normaly. The authors linked the colouration to either environmental stress or possible inbreeding effects of the isolated population in the Mediterranean Sea. The complete article with pictures can be found here: https://www.researchgate.net/publication/347561389_A_LEUCISTIC_WHITE_SHARK_CARCHARODON_CARCHARIAS_LAMNIFORMES_LAMNIDAE_FROM_THE_NORTHERN_AEGEAN_SEA_TURKEY.

Shark speed

name change

the name great white shark is out dated and through campaigns to protect them the name has bean changed to white shark, as well as attempting to combat discrimination (its a breach of the anti discrimination act). Also "greater" and "lesser" animals (ie greater and lesser adjutant stork) are commonly used to differentiate between two similar species, the white shark is the last extant species in its genus (none named lesser white shark) also great white could be confused with lesser white sharks (an other name for white tip sharks) Realfakebezalbob (talk) 14:52, 18 July 2022 (UTC)

You will have to demonstrate a solid shift in name use in reliable sources for this to be an option, and that is clearly not happening. --Elmidae (talk · contribs) 15:20, 18 July 2022 (UTC)

In the scientific literature there seems to be a preference for 'white shark' over 'great white shark'. This is based on pubmed search results, compare:

https://pubmed.ncbi.nlm.nih.gov/?term=%22great+white+shark%22 (38 results, 13 in the last 5 years)

https://pubmed.ncbi.nlm.nih.gov/?term=%22white+shark%22++NOT+great (83 results, 46 in the last 5 years)

So I think there is some evidence for the preference for 'white shark' over 'great white shark'. I do not know any convenient ways of comparing more "popular" literature. Carcharias taurus (talk) 09:01, 19 July 2022 (UTC)

http://www.elasmo-research.org/education/white_shark/ws_or_gws.htm

also many ichthyologists and other scientist are beginning to use the name signaling a shift in naming (example http://elasmollet.org/PublicationsOthers/Francis%20white%20shark%20reproduction.pdf with no mention of "great white shark" rather "white shark") Realfakebezalbob (talk) 16:31, 21 July 2022 (UTC)

You have a good point about the general scientific trend of preferring "white shark" over "great white shark," but it's not clear whether this shift is prominent enough vernacularly (see Etymology and Naming History in Taxonomy). There's a reason why it took so long for Killer whale to be moved to the more appropriate name Orca despite the latter's prominent usage for decades. I recommend making a move proposal and laying out your arguments, with focus on evidence of a trend in greater vernacular usage for "white shark." Macrophyseter | talk 18:58, 13 November 2022 (UTC)

Strongly opposed to this change. It doesn't matter what scientists prefer, because neither "great white shark" nor "white shark" are scientific names, they're common names. Scientific sources are an authority on what the taxonomy of the species is, but not on what the common name is. Just like our own article Common name says: "a common name of a taxon or organism (also known as a vernacular name, English name, colloquial name, country name, popular name, or farmer's name) is a name that is based on the normal language of everyday life". No non-scientific sources are using the name "white shark" because almost no one outside scientific circles would know what that refers to, whereas the name "great white shark" is probably one of the most well-known shark names in the English-speaking world. Steven Walling • talk 03:14, 14 November 2022 (UTC)

"But before we go any further, some technical clarification is needed.  Most shark scientists refer to Carcharodon carcharias by its official common name, “White Shark.”  I think calling them “Great Whites” was something that stuck in the public’s mind when that’s how fictional marine biologist Matt Hooper referred to the shark in JAWS" there is great effect on pop culture on science and vise versa. In addition it is an understatement that nonscientific sources dont use the term "white shark." Also I find it very hard to believe someone would be so, brain dead (for lack of better words) to think what they know to be a 'great white' referred to as a 'white' and not connect the dots; then again there are those types of people out there!

There's an even simpler example that proves my point. Even if you search for "white shark" specifically in quotes, nearly 100% of the news stories have titles and article content that say "great white shark". The same is true in Google Books search.

only the last three have great mentioned in them Realfakebezalbob (talk) 23:52, 14 November 2022 (UTC)

no one is doubting it is still used Realfakebezalbob (talk) 23:52, 14 November 2022 (UTC)

in addition the majority of government sources prefer white over great white Realfakebezalbob (talk) 00:08, 15 November 2022 (UTC)

You just cherrypicked a tiny number of source examples when there are thousands of results that favor "great white shark" as the common name. Not very convincing. Steven Walling • talk 01:42, 15 November 2022 (UTC)

Taxonomy (Etymology correction needed)

Based on the Romanization of the Greek and meaning prescribed to it, I believe this section is incorrect: [It is a portmanteau of two Ancient Greek words: the prefix carchar- is derived from καρχαρίας (kárkharos), which means "jagged" or "sharp".] Rather than καρχαρίας (karkharías), I believe they meant to use κάρχαρος (kárkharos), which means "jagged" or "saw-like". 141.239.93.31 (talk) 07:52, 31 January 2023 (UTC)

Maximum Size

I found the article slightly inconsistent with the maximal size of this species. The lead threw a data of 5.8m while the section mentioned 6.1m (verified length) with this source. Do we have to make it 5.8 to 6.1m in the lead?

Besides, other articles, including Saltwater Crocodile & Black Caiman, adopt data of maximum sizes from those "unconfirmed reports" as well. Do we have to at least mention some of those largest estimations in the size section? For instance, the salt croc page has its lead throwing a maximal length of 6 meters & a mass of 1300 kilograms while claiming the largest estimated statistics of such as 7 meters & a jaw-dropping 2000 kilograms (crazy for a land reptile).

Apex predator

Looking to obtain a consensus regarding the sentence in the intro paragraph, "The great white shark is an apex predator, as it has no known natural predators other than, on very rare occasions, the orca." An apex predator, by definition, is "a predator at the top of a food chain, without natural predators of its own." Would it be fair to say that the great white shark cannot be an apex predator as it does have a documented natural predator, the orca. The word "rare"? I'd argue that is up for debate; it seems to be more common or at least documented more often now (reference is from 2005), particularly in South Africa and sometimes California. I believe this sentence needs to be amended. I propose - "The great white shark has only one documented natural predator, the orca". Thoughts? Bloodyboppa (talk) 22:00, 15 June 2023 (UTC)

I think the sentence should be eliminated entirely. It might be true that for adult great white sharks, their only non-human predator is the orca, but newborn great white sharks are only about 4–5 feet long, and great white sharks grow very slowly. Scientists believe that most great white sharks never make it to sexual maturity because of predation from various species of sharks, including larger great white sharks. Why should predation not count if it's only the juveniles being killed? Muéro^(talk/c) 18:09, 11 August 2023 (UTC)

Edit request, update to mistaken identity & addition of Oceanic White Tips, July 2023

I'm a wiki edit noob, if anyone would like to help it would be appreciated; both corrections are under Shark Bite Incidents:

Currently: "Of all shark species, the great white shark is responsible for by far the largest number of recorded shark bite incidents on humans, with 272 documented unprovoked bite incidents on humans as of 2012." First, it's now 10+ years since 2012 so the stats should be updated but next, for context, it should be noted that the Oceanic White Tip has probably killed more which is noted in the "Shark Attack" wiki. It states: "The oceanic whitetip has probably killed many more castaways, but these are not recorded in the statistics." and here is the source they use yet there are multiple sources: http://animals.howstuffworks.com/fish/most-dangerous-shark2.htm

-Currently: "Contrary to popular belief, great white sharks do not mistake humans for seals." its source is from a 19 year old apparently outdated Nat Geo article. There was a more recent 2021 well-fund study that says the exact opposite and even Nat Geo cites this in various articles. Perhaps something like the following could be added: "A study provides the first evidence in agreement with the ‘mistaken identity theory’, in which white sharks bite humans because of their visual similarity to their natural pinniped prey.

Adding GWS liver context for how large and nutrient their livers are

Many assume a GWS's liver is tiny and wonder why Orcas kill them for their "tiny" liver...First they have two sides or lobes of their liverhttps://dlnr.hawaii.gov/sharks/anatomy/the-shark-inside/#:~:text=Shark%20livers%20are%20huge%2C%20consisting,lobes%20surrounding%20the%20digestive%20tract.

Second... "Great white shark livers are huge, weighing in at hundreds of kilograms. And they're packed with calories, obtained from the fat of the seals they eat. According to a 2013 paper, a 456-kilogram (1,000 lbs) great white shark liver contains around 400 litres of oil - delicious, calorie rich oil. This helps to keep the sharks buoyant and supplied with nutrients as they migrate.

It's also a really tasty treat for orcas: like eating a fatty doughnut, or bacon fried in butter - not just a delicacy, but a deeply sustaining meal in the often harsh conditions of the oceans." https://www.sciencealert.com/watch-orcas-surround-and-scare-off-the-ocean-s-most-terrifying-predator NotBond007 (talk) 18:38, 8 August 2023 (UTC)

Attacks fewer than 10 per year wrong

Argument in Description that attacks occur fewer than 10 times per year is wrong. As stated in the source nr 18, "deadly attacks" (!) are mostly fewer than 10 times per year. In the same article 2020 is called a low year for attacks with 57 reported attacks. 2A00:6020:5023:F700:3908:89D5:642B:25B0 (talk) 21:50, 11 January 2024 (UTC)

Edit request

In Anatomy and Description, under size, there seems to be an error: "In great white sharks, sexual dimorphism is present, and females are generally larger than males. Male great whites on average measure 3.4 to 4.0 m (11 to 13 ft) in length, while females measure 4.6 to 4.9 m (15 to 16 ft)." Trnsfrcashcorson (talk) 18:35, 29 January 2024 (UTC)

Not done – please clarify I'm... not sure what the error is? Nothing about that quote is self-contradictory, and it's directly supported by the reference at the end. Could you clarify what you want changed and why?

Name of article/species.

The proper name should be "White Shark." "Great white shark" is the improper common name. The name of the article and all subsequent references should be changed to "White Shark." The opening sentence should read as "The white shark (Carcharodon carcharias), also known as the great white shark..." 134.186.51.126 (talk) 04:31, 19 July 2024 (UTC)

Can you provide some reliable sources that state that the proper/more common common name is "white shark" and not "great white shark"? Mr Fink (talk) 05:35, 19 July 2024 (UTC)

 Not done Consensus for over two decades has been that the WP:COMMONNAME here is "great white shark," not "white shark." You're welcome to open a move request if you disagree with it, but keep in mind that it would have a snowball's chance in hell at going through. — Kodiak Blackjack (talk) • (contribs) 15:33, 3 August 2024 (UTC)

Semi-protected edit request on 31 July 2024

Under "interspecific competition and predation by orcas", the 14-foot (3.5-meter) female with sustained wounds after an encounter with orcas near Seal Island off False bay, South Africa, in 2017, should be made referenced to. As it possibly suggests white sharks can survive killer whale attacks; that a predation attempt by orcas is not certain death. Furthermore, possibly reasons as to why the shark survived should be noted, such as the idea that sharks may be diving into deeper waters upon sensing orcas near their location, or that white sharks are 'fighting back', leading to the orcas backing off, or, lastly, the possibly that the orcas are only toying with the shark.
