Gestation
[edit]An article on the Eastern Grey Nurse Shark in the Life supplement of The Guardian, from 17th February, records the gestation period as about twelve months, but also points out that no one is quite sure how long it takes. Chenxlee 16:32, 24 Apr 2005 (UTC)
Name
[edit]I know the article does say 'Sand Tiger' as another name, but wouldn't this be better kept under Sand Tiger than 'Grey Nurse'? —Preceding unsigned comment added by 67.162.31.148 (talk) 03:08, 3 March 2008 (UTC)
- For fish article we use WP:FISH#Fish names and article titles as the rule, and since fishbase call it sand tiger so do we. --Stefan talk 06:05, 3 March 2008 (UTC)
I don't understand. You're saying we call it Sand Tiger Shark but the article is at Grey Nurse Shark. Shouldn't it be moved to Sand Tiger? --67.162.31.148 (talk) 01:40, 17 March 2008 (UTC)
- I'm saying, as per the article, it is called grey nurse in Australia, spotted ragged-tooth in Africa and sand tiger in the US and UK, all is correct, wikipedia is international and WP:FISH have stated that we should use then name that fishbase uses, fish base calls this shark grey nurse shark so therefore the page is correctly named, sand tiger and spotted ragged-tooth both have redirect. --Stefan talk 02:26, 17 March 2008 (UTC)
Jesus, you clearly have no clue what you're saying. First you say that fishbase calls it a sand tiger (which it does) , and then you turn right around and say fishbase calls it a grey nurse (which it does not). The article is incorrectly titled and sand tiger should be used. —Preceding unsigned comment added by 70.109.15.202 (talk) 17:38, 14 May 2009 (UTC)
Fishbase seems to refer to it as the Sand Tiger Shark on my computer though. I don't understand, has fishbase changed the name since that's what fishbase uses? I'm so confused... --JohnVMaster (talk) 01:36, 21 August 2008 (UTC)
- I agree. Nobody calls this fish a 'grey nurse shark' outside australia. 'Sand tiger shark' is a much more internationally common name. Before seeing this article I wouldn't have had a clue what a 'grey nurse shark' referred to, despite being perfectly familiar with sand tigers. This could easily confuse people. If there's even a policy about naming according to fishbase which hasn't been followed, why hasn't this article been moved? 86.26.78.54 (talk) 09:08, 10 March 2010 (UTC)
To add to this confusion there's a separate article for Sand Shark which appears to be the same species. —Preceding unsigned comment added by 93.97.50.134 (talk) 16:05, 23 August 2010 (UTC)
The article now also claims that "Grey Nurse" is commonly used in the UK, which it is not. It has always been the Sand Tiger Shark. A potential source for this misconception could be that when Nintendo localised the game Endless Ocean 2 for Europe, they used the Australian translation because both regions use the PAL format, assuming they would be interchangeable. — Preceding unsigned comment added by 82.33.96.230 (talk) 00:04, 14 July 2015 (UTC)
Genus
[edit]Discovery channel sources put Odontaspis as the genus for this shark, rather than charcharias. Is this simply a difference in opinion or a change in taxonomy? —Preceding unsigned comment added by 69.181.74.232 (talk) 05:11, 1 August 2008 (UTC)
- Many species are being moved or debated on where they belong in the taxonomy tree. In wikipedia we use fishbase, see reference in the article, as our main source for fish taxonomy, what is correct is not obvious. Changes in taxonomy happen very slowly, and I doubt there is an entity that everyone accepts as being the 'correct'. So as to answer your question, yes, both difference in opinion and possibly a change happening that is not accepted by fishbase yet. --Stefan talk 06:14, 1 August 2008 (UTC)
This article should be under Sand tiger shark rather than grey nurse according to the fishbase rules. —Preceding unsigned comment added by 86.219.5.241 (talk) 10:26, 19 April 2009 (UTC) I think it should not evem be a shark
Two articles merged
[edit]Ragged tooth shark redirects to Smalltooth sand tiger yet it should merged with this article. —Preceding unsigned comment added by SlackersHammer (talk • contribs) 09:09, 28 August 2008 (UTC)
Factual issue
[edit]I dispute the claims that the shark is "not aggressive unless provoked." The international shark attack file has instances of unprovoked attacks, including fatal attacks. In South Africa, especially in the "raggie" has a reputation for being aggressive. —Preceding unsigned comment added by 63.226.104.225 (talk) 15:48, 14 August 2009 (UTC)
Citations
[edit]I formatted the reference section and it is set up for books if you use any. However, the original citations are all over the place. Many are just web addresses. You will need to insert the "cite web template", then follow the actual link to complete the required information. This will take time. If you are not comfortable with the web resources that were there, then delete the citation and attempt to cite the info from another source. There is a section I called Additional reading which consist of random web links not in the actual text. Either use them - thus moving them under references or delete them completely.--JimmyButler (talk) 03:15, 22 October 2011
Okay, I will work on all of the original citations this weekend. Some of them are not legitimate, so I'll probably end up deleting those. All of the rest of the useful sources I will convert. Also, the reason why I added the external links/additional reading area is to keep the sources at hand for future use just to save time. I will delete them now and bookmark the sites instead on my computer. Thank you so much for the help, I was going to ask you about the unformatted sources on Monday. This saves me a lot of time. --UND77 (talk) 23:19, 22 October 2011 (UTC)
Range description
[edit]The range map is very good. The range description is very uneven in detail. Three particular sightings for Canada and a very sweeping statement for the Pacific ocean. I think it would be a good idea to describe the map. There is a limited number of coastlines marked. The source of the map could then be the source cited for the text. --Ettrig (talk) 09:36, 9 November 2011 (UTC)
Thank you for your suggestions, I will get on that right away! --Theawesomestpersonyouwillevermeet (talk) 00:54, 10 November 2011 (UTC)
Comments
[edit]- Consistent capitalization of the name, sand tiger shark, Sand tiger shark OR Sand Tiger Shark.
- Stick to one common name.
- The English language article should not say what the phenomenon is called in other languages.
- Harmless belongs in Behaviour rather than in (Physical) Description.
- Lastly (in Description) is not the last thing. This has a sharp smell of plagiarizing. Haven't checked whether it is.
- Done (Just a communication error between multiple writers, thank you for alerting us.) --Theawesomestpersonyouwillevermeet (talk) 00:33, 30 November 2011 (UTC)
- They live both in the surf of waters AND at depths of between 60 and 190 m. This requires some kind of reconciliation.
- at depths of between 60 and 190 m belongs in Habitat rather than in Behaviour. This is difficult: Maybe better to group Habitat and Behaviour.
- More wikilinks are needed.
- What do you suggest I link? Should I just link things that I might need clarification on if I were a reader of the article?
- I am not good at this. But what you suggest is what I have seen others suggesting. You might want to take a look at Wikipedia:Manual of Style/Linking, but try to not be lost in all that text. --Ettrig (talk) 14:54, 28 November 2011 (UTC)
- There is repetition in ghe Behaviour chapter.
- Minor repetition in Reproduction. Suggestion: sort statements chronologically along the process.
- This is complete to the best of my ability. --Theawesomestpersonyouwillevermeet (talk) 00:33, 30 November 2011 (UTC)
- Replace external links in Conservation status with wikilinks.
- One or two more pictures, there are many in Commons
Done, but how do I place them throughout the article? They keep drifting to the left side...--UND77 (talk) 03:02, 29 November 2011 (UTC)
- Tick off the items done. Discuss the one's you disagree with.
- When you can think of nothing more to do, kindly ask user:Yzx to comment. That user seems to be very interested in sharks.
Will do, thank you so much. --UND77 (talk) 03:02, 29 November 2011 (UTC) --Ettrig (talk) 10:34, 12 November 2011 (UTC)
- The description section seemed to deviate adequately from the source, these sections tend to be difficult to re-write. The use of "Lastly" was just illogical ... in this case not copy/paste and thus placing it out of context. Although students do blunder like that frequently - a dead give away for plagerism. I did find this; which I assumed plagiarized Wikipedia and not the other way around!
- Description: Sand tigers have many features that distinguish them from other shark species. Their mouth extends beyond their eyes, and they usually swim with their mouth open. Their snout is flattened with a conical shape and their body is stout and rather bulky, with two large dorsal fins that are almost equal in size. The tail is elongated andhas a long upper lobe, and the dorsal fins are set back almost beyond the pectorial fins. The pectoral fins are triangular, and the tail is almost one-third as long as the head of the shark. The Sand tiger shark's head is rather pointy, not round and the teeth are smooth edged and sharp-pointed. People normally associate the Sand tigers with the demeanor of being vicious because of their teeth protrude from their mouths when their jaws are closed; however, they are generally quite harmless. The Sand tiger shark usually has a grey back and white underside. It also has grey dorsal fins. Biological Profile
- This has to be a first.. a students paper being plagiarized by another entity and not the other way! We are making history here. Thanks for the list; students seemed to perform well when the problems are defined. I of course look to see if they ignore them... let us hope this will not be the case.--JimmyButler (talk) 23:07, 13 November 2011 (UTC)
Thank you! I will take care of your list as soon as possible. --Theawesomestpersonyouwillevermeet (talk) 13:01, 14 November 2011 (UTC)
Just to clarify, what do you suggest I do to improve the International common names section? Should I just delete it altogether? --Theawesomestpersonyouwillevermeet (talk) 03:08, 15 November 2011 (UTC)
- Yes, my suggestion is to delete all statements about what this animal is called in other languages. --Ettrig (talk) 08:19, 15 November 2011 (UTC)
Thanks, I'll make sure to always call it the Sand tiger shark! --Theawesomestpersonyouwillevermeet (talk) 13:00, 15 November 2011 (UTC)
- Per MOS:CAPS it's lower case 'sand tiger shark'. Regards, SunCreator (talk) 17:27, 15 November 2011 (UTC)
Very few comments remain for processing now! --Ettrig (talk) 14:54, 28 November 2011 (UTC)

Smalltooth sand tiger
[edit]Maybe the article Smalltooth sand tiger can be an inspiration to this article. It is GA. It is about one of the other three species in the family. It might have citations of sources that are also relevant to this species. --Ettrig (talk) 17:00, 15 November 2011 (UTC)
Perfect! This is extremely useful. Thanks!--UND77 (talk) 03:03, 29 November 2011 (UTC)
Inside the Animal Mind
[edit]- The sand tiger shark enjoys hunting in the surf of waters. Attributing a human emotional state to an animal is a common mistake. Even under carefully controlled experiments, it is difficult for behavioral biologist to attribute an emotion with an action. Typically humans draw conclusion based on their own perspectives of emotion. For example, dolphins are happy = they are always smiling. The fact that their mouth is fixed into a perpetual grin may lead us to wrong conclusions. My cat loves me, he is rubbing my legs - nope - he is marking territory with scent glands in his checks. I would like to think the shark enjoys hunting in the surf; however, I suspect the shark feels no emotion - happy or sad - in this endeavor. The term is Anthropomorphism. I'll teach this when we cover animal behavior. --JimmyButler (talk) 23:23, 29 November 2011 (UTC)
- I was actually curious about this. I thought that because cats, dogs, etc. seemed to have enjoyments, every animal was that way. That is very interesting. Thank you for the clarification. I changed all the occurrences of it. --UND77 (talk) 00:14, 30 November 2011 (UTC)
- Excerpt from cat communication: Touching noses is a friendly greeting for cats, while a lowered head is a sign of submission. Some cats will rub their faces along their guardian's cheek, hands, or ankles as a friendly greeting or sign of affection. This action is also sometimes a way of "marking their territory", leaving a scent from the scent glands located in the cat's cheeks. More commonly, a cat will do a "head bonk" (or "bunt"), i.e., bump someone with the front part of its head to express affection.[1]

- Sand tiger sharks will often shelter in caves or gutters during the day. I must confess my ignorance. What is a gutter, I'm guessing not the place that the hapless and homeless end up when they are destitute as in "Jimmy if you don't straighten up you'll end up living in the gutter" (Granpa, 1977).

- Humans do not generally serve the Sand tiger as a diet resource, however, the shark has been know to attack a few humans. I found myself making numerous edits, as I attempt to increase verbal efficiency. See here for examples. You seem to rely on a lot of weasel words --- words you can't pin down as wrong such as "few" and "many". These terms are open to opinion and thus useless. This sentence is typical of what I am seeing.
- I will read through the article extremely carefully, and make sure that the weasel words won't be in there. Sorry about that, I really have to separate my English writing from my Scientific writing. I will try not to make the same mistakes. --UND77 (talk) 17:46, 1 December 2011 (UTC)

Taxonomy
- The sequence of events here isn't quite right. For example:
- Triglochis and Eugomphodus are genus names, not species names. Thus, Muller and Henle's proposed name was Triglochis taurus.
- ICZN Opinion 47 gave precedence to Carcharias. By seeking to repeal it, Tucker, White, and Marshall actually wanted Odontaspis to be the genus name, and the request was approved by the ICZN.
- The name Compagno first proposed was Eugomphodus taurus (see above). He was largely responsible for reverting the name back to Carcharias taurus (ICZN Opinion 1459).

- The sequence of events during gestation is a bit simplified. Multiple embryos develop in each uterus, and the dominant embryo kills and eats the others. Thus, there is only ever one embryo brought to term per uterus (up to two total), and this species exhibits both ovophagy and sibling cannibalism. It's the only shark known to do this.
- Thank you! That clears the confusion of the process. Also, is there a resource that states that the sand tiger is the only known shark to do this type of reproduction. I have read many articles on this, but I have yet to find that fact. --UND77 (talk) 17:44, 1 December 2011 (UTC)

A few observations so far, more to follow:
- Lead
- "Two behaviors set the sand tiger apart from other sharks: its method of reproduction and its ability to gulp air from the surface to allow it to float effortlessly throughout the water." I've got so many problems with that sentence. First of all, the Description section says that "Sand tigers have many features that distinguish them from other shark species", but here we're told there are only two. Secondly, in what sense is its method of reproduction a behavior? And thirdly, what does "float effortlessly throughout the water" mean?
- DONE --UND77 (talk) 23:38, 7 December 2011 (UTC)
- "It also dwells in the waters of Japan, Australia, South Africa, Great Britain, and Scandinavia". The range map doesn't show it in either the waters around the UK or Scandinavia.
- DONE--UND77 (talk) 23:38, 7 December 2011 (UTC)
- Scientific naming process
- "The scientific name has since undergone many disputes ...". A name can't undergo disputes, but it can be disputed.
- DONE--UND77 (talk) 23:38, 7 December 2011 (UTC)
- What does "requested to repeal" mean? And what does "repeal" mean in this context anyway?
- DONE--UND77 (talk) 23:38, 7 December 2011 (UTC)
- "However, many taxonomists and experts question his change saying that there is not a significant difference between Odontaspis and Carcharias. However, after changing the name to "Eugomphodus taurus" ...". Need to do something about that "However ... However"; "however" is a much overused word.
- DONE--UND77 (talk) 23:38, 7 December 2011 (UTC)
- "He proposed the name because it fit best to the characteristics of the shark because "Carcharias taurus" means ...". Similarly here, "because ... because". And what do you think of "fit best"? I don't think much of it. "Best fitted the characteristics ..."?
- DONE--UND77 (talk) 23:38, 7 December 2011 (UTC)
- Behavior
- "However, biologists observed that the sand tiger swallows their prey whole 93.7 percent of the time". Another one of those "howevers", but more importantly, "the sand tiger swallows their prey"?
- Note the number signals, tiger is one, their is 2 or more. --Ettrig (talk) 09:57, 7 December 2011 (UTC)
- I've got another problem with this sentence, which is to do with the statement that sand tiger sharks swallow their prey whole 93.7% of the time. First of all, biologists haven't observed all sand tigers, just a sample of them, so all that can be said is that among that sample prey was swallowed whole 93.7% of the time. Secondly, the precision to one decimal place seems absurd to me; surely the point is that biologists have observed that sand tigers almost always swallow their prey whole; if this study was to be repeated, what do you think the chance of coming up with 93.7% again would be? Zero? Malleus Fatuorum 22:17, 7 December 2011 (UTC)

- DONE--UND77 (talk) 03:06, 8 December 2011 (UTC)
- Conservation status
- "These estuaries are very susceptible to point source pollution that can be extremely harmful to the pups." What the source says is "juvenile sand tiger sharks are commonly found in estuaries of the eastern U.S. that are susceptible to non-point source pollution." (My emphasis.)

Suggestion
[edit]Hi!
Saw that this article was part of a school project, though I should give some suggestions.
- In the lead, I would add a estimated water death for "epipelagic and the mesopelagic regions" which most normal people have no idea on how deep it is.
- DONE--UND77 (talk) 03:37, 8 December 2011 (UTC)
- "After mating, a unique embryonic development process", is this really unique? I though it happened in other sharks also??
- DONE--UND77 (talk) 03:37, 8 December 2011 (UTC)
- Shouldn't spotted ragged tooth and blue-nurse sand tiger be added to the first scentence, not sure but think so, maybe need to check some guidelines??
- "The sand tiger's eyes tend to be smaller than other sharks and lack eyelids" change to 'and it lacks eyelids'
- DONE--UND77 (talk) 03:37, 8 December 2011 (UTC)
- "These teeth are very unique to this species of shark" hum, is there any sharks or any other species for that matter that does not have unique teeth?? I think I understand the point that is trying to be made, but I think it should be reworded??

Thank you for recognizing that! Any review or suggestion is extremely useful. This is great! Thanks again! --UND77 (talk) 03:37, 8 December 2011 (UTC)
- And here's my additional suggestion. Leave this article for a couple of days and then come back to it with fresh eyes. Try to forget it's something you've worked on and instead look at it as a regular reader coming across it for the first time would. Right now it really doesn't hang together: the sharks never attack unless provoked, but there are 29 reported cases of unprovoked attacks ... no need to rush it, take your time. Malleus Fatuorum 03:16, 8 December 2011 (UTC)
- I will definetely do that. I just need to take my time. Of all the edits I have done, have I done them correctly? Do they make sense? Especially the unprovoked attacks edit. I tried to make it as connected as possible. Thanks for your help Malleus. I really appreciate it. --UND77 (talk) 03:37, 8 December 2011 (UTC)
- You're doing fine, but softlee, softlee, catchee monkee. Give yourself a break of a day or two and then come back and read the article like anyone else would. Malleus Fatuorum 03:49, 8 December 2011 (UTC)
- What do you think Malleus? I tried to go through it carefully, trying to get things more understandable. I saw where you were coming from. After taking a break, I was able to notice problems much clearer. Thank you very much. --UND77 (talk) 00:22, 14 December 2011 (UTC)
- Looking good. It's like you have to step outside yourself, and look at the article as if it was written by someone else. The best thing of all, I think, is when you look back on something you wrote years earlier and think "Wow, did I really write that? It's fantastic!" Malleus Fatuorum 00:35, 14 December 2011 (UTC)
- YES! That's exactly what happened! Some things I thought, "Why in the world would I use that word here?", but the greatest feeling was "Holy mackerel! This is awesome!" I can't wait for the day when someone asks me about the Sand tiger (if that day ever comes), and I can tell them a random fact or just say, "Hey! Check out the article on Wikipedia! I wrote it." Do you think the article is ready for a GA review? Thanks again Malleus. --UND77 (talk) 01:51, 14 December 2011 (UTC)
- No I don't, not quite. Check out the Interaction with humans section for instance. That needs some work. Malleus Fatuorum 02:06, 14 December 2011 (UTC)
Maybe worth keep a check on nervous shark, it's a recent good article nominee. Regards, SunCreator (talk) 00:52, 9 December 2011 (UTC)
Sand Tiger vs Sand Tiger Shark
[edit]I'm not sure if this is really an issue, but in some places you refer to it as a Sand tiger, and in others it's the Sand tiger shark. I'm not doing an animal article, so I'm not sure the rule behind this, but I suspect it might just be an issue of consistency? I just thought I'd bring this up. If it is a problem, it would just be a simple fix. Phorofor (talk) 19:59, 9 December 2011 (UTC)
- I assumed that if I put "Sand tiger shark" that "sand tiger" would be okay too. I don't think it matters though. Thank you for bringing it up! It made me read through my article again. --UND77 (talk) 21:23, 13 December 2011 (UTC)
How many words does we need Mr. B. fo da A
[edit]As far as the sand tiger's location in the water column, it roams... Conversational dialog not expedient enough for my taste. Four students in the group, one of you please read through this thing and remove the words that contribute nothing to the understanding of this topic... we are not trying to reach a "word count" for a class paper. Errrrrr....--JimmyButler (talk) 00:57, 13 December 2011 (UTC)

This is the next article that I will be reviewing after somewhat of an absence from GAN. If you get a chance, I would appreciate it if you helped peer review periodic table at Wikipedia:Peer_review/Periodic_table/archive1. StringTheory11 05:30, 20 December 2011 (UTC)
Thank you so much for taking the time to review my article. I greatly appreciate it. I will try to address all of your concerns as soon as possible. Also, I'll try to check out the periodic table and peer review it. I probably won't get to it by Christmas, but I can definitely look at it after Christmas and New Year's. Thanks again!--UND77 (talk) 02:54, 21 December 2011 (UTC)
Note: I have placed this article on hold until the problem areas are fixed. After that, I will look at it again to determine if it passes the GA review. Because the nominator has said that they will be away until December 26, I will give longer than the customary seven days. StringTheory11 02:51, 23 December 2011 (UTC)

General
[edit]- This article could benefit from more peer-reviewed journal articles as sources. Try to find at least one or two more before this article is passed.
- The image captions seem a bit too minimalistic and could benefit from expansion (e.g. for the snout image, explain what we are seeing, for example "snout of a sand tiger shark, showing small eyes.")
- Done--UND77 (talk) 02:38, 21 December 2011 (UTC)
These are the only recurring problems I see. I will look at the sections in more detail later. StringTheory11 05:41, 20 December 2011 (UTC)
Taxonomy
[edit]- The common names section should probably be moved out of this section and into its own level-2 section at the bottom of the article.
- Done--UND77 (talk) 02:46, 21 December 2011 (UTC)
- Why does the shark have many common names? Is there a reason that people didn't come up with one name originally when it was discovered?
- The shark was found in so many different areas, so those who found it made up their own names. Today, most of those names are still used by the places listed. I used the sand tiger as the main common name because it was the name on FishBase that recurred in multiple places worldwide. But I thought that if I listed the other common names, it would ease any controversy. --UND77 (talk) 02:46, 21 December 2011 (UTC)
- Changing the first sentence to something like "Since the shark has been found in many different areas before a name could be standardized, it has many common names" would probably work well. StringTheory11 05:28, 21 December 2011 (UTC)
- Please clarify what you mean by "a somewhat unknown classification."
- Please define "ICZN" in the article.
- Would listing International Commission on Zoological Nomenclature be enough, or should I state the commission's purpose as well?--UND77 (talk) 02:46, 21 December 2011 (UTC)
- That should probably be enough. StringTheory11 05:28, 21 December 2011 (UTC)
- Done--Theawesomestpersonyouwillevermeet (talk) 04:19, 23 December 2011 (UTC)
- Second-to-last and third-to-last sentences in naming process subsection could probably be combined into one.
- How did Compagno play a "key role" in renaming the shark to its current name?
- Perhaps change to "successfully advocated" for the classification - if that reflects his role.--JimmyButler (talk) 04:41, 21 December 2011 (UTC)
- Done--Theawesomestpersonyouwillevermeet (talk) 00:54, 29 December 2011 (UTC)
This is all I notice for this section. I will do the next later. StringTheory11 18:21, 20 December 2011 (UTC)
Hi, I've been looking in on this and I should note that the section still has inaccuracies:
- Agassiz's name was Odontaspis cuspidata. Note the "a".
- O. cuspidata is not a synonym of C. taurus, but is congeneric. Agassiz placed C. taurus in Odontaspis because he thought Carcharias and Odontaspis were synonyms.
- Odontaspis taurus became more frequently used than Carcharias taurus because Odontaspis was more commonly used, especially for fossil species.
- The ICZN first decided in favor of Carcharias (Opinion 47), making Odontaspis a synonym.
- Tucker, White, and Marshall argued in favor of Odontaspis, and the ICZN agreed, giving priority to Odontaspis and making Carcharias a synonym (Opinion 723)
- Compagno re-established Carcharias and Odontaspis as separate genera, which ICZN approved (Opinion 1459)
- Carcharias is from karcharos "jagged" -- it doesn't mean "jagged tooth"; that's what Carcharodon means.
- What, then, does the name mean? I am confused!--Theawesomestpersonyouwillevermeet (talk) 00:59, 29 December 2011 (UTC)
- taurus means "bull", but the name doesn't have anything to do with the bull shark.
- Nothing in the name means "shallow water"
- Scientific names should always be italicized, not put in quotes.
You'll need additional sources to support this. At the moment the section has only one reference, which doesn't meed verifiability criteria. -- Yzx (talk) 20:19, 21 December 2011 (UTC)
Description
[edit]- Explaining why humans think the shark has its characteristics instead of just explaining what they are would help a whole lot. Not necessary for facts such as length and weight, but, for example, the fact that it has reddish brown spots seems interesting and could use explanation as to why the sharks have them.
- The sentence about the albino specimen should probably get its own paragraph.
These are the only problems in this section. The rest will come soon. StringTheory11 19:54, 21 December 2011 (UTC)
Diet
[edit]- This whole section could probably be a subsection of behavior.
- Last sentence needs a reference.
- Done, I just deleted the sentence because I could not find an exact reference. Do I need more information in the diet section?--Theawesomestpersonyouwillevermeet (talk) 04:07, 26 December 2011 (UTC)
- Not if it's a subsection of behavior. If it weren't, you would need more info, but as a subsection it is OK. You may need more for FAC, but that's not something to come to right now. StringTheory11 19:28, 26 December 2011 (UTC)
- The whole section seems wordy, and could use a rewrite.
StringTheory11 21:54, 21 December 2011 (UTC)
Behavior
[edit]- First sentence needs a ref.
- The whole section should refer to the sharks as either singular or plural, not switch between the two.
- The last sentence should be put in the "interaction with humans" section.
StringTheory11 20:02, 22 December 2011 (UTC).
Habitat and range
[edit]- Sentence about Canada needs a ref.
- Whole section seems like it was just put together one sentence at a time. It needs to flow more smoothly. I recommend a rewrite.
I rearranged the sentences to improve the flow of the section, but please let me know if you think a more intensive rewrite is in order.--Theawesomestpersonyouwillevermeet (talk) 18:25, 24 December 2011 (UTC)
- Looks much better now. StringTheory11 22:42, 24 December 2011 (UTC)
StringTheory11 02:51, 23 December 2011 (UTC)
Reproduction
[edit]- Is there a reason why they have a low reproduction rate?
- Why does the female stop feeding?
StringTheory11 02:51, 23 December 2011 (UTC)
Conservation status
[edit]- Second and third sentences should be merged.
- Explain exactly what "prohibited species" means or link to the appropriate article.
- Info about how the shark is prepared for food is not necessary.
StringTheory11 02:51, 23 December 2011 (UTC)
- Why are refs that are web sites such as "thetelegraph.com.au." in lower case? Shouldn't they be the same pattern (Fish...) as other web site publishers? PumpkinSky talk 03:08, 23 December 2011 (UTC)
I'm not quite sure; I will check it out. Thank you.--Theawesomestpersonyouwillevermeet (talk) 20:10, 30 December 2011 (UTC)
Reproduction Section Needs Attention
[edit]The reproduction section is a mess and needs attention. It is stated that they have one of the lowest reproduction rates and yet the reasons for this are not adequately explained.
1. "During early embryonic stages the young absorb nutrients from a yolk sac"
The initial number of young is not given. It is as many as 40 between the two uteri. I have seen one source say 40 in each uterus, but most state the former and it appears to be more accurate.
2. "At approximately 10 centimeters (4 in) in length, developing embryos in the mother's uteri are killed and devoured by two surviving pups, a process called intrauterine cannibalism (oophagy)."
Using "killed" is unnecessary and humanizes the biological process. In fact, "killed and devoured" is a melodramatic statement that is completely inappropriate for a zoological article, as is the term "mother." It is also poorly explained; no reason for this behavior is given. In addition, the phrase "by two surviving pups" is both inconsistent (they are referred to as embryos in the former part of the sentence) and vague. It suggests that these two are somehow either preselected or farther developmentally advanced than the others. In reality it is more of a "free for all," with the strongest and most aggressive embryo in the uterus being the survivor.
At two months of age (which likely coincides with 4 inches of length) the individual yolk sacks of the embryos run out and they must utilize the only other food source available to keep themselves from starving. The embryos begin consuming one another and continue until only the largest and strongest embryo in each uterus is left.
3. "There are reports of biologists probing the bellies of landed females and having their fingers nipped by the cannibalistic young with their fully developed teeth"
Irrelevant to the reproduction of this species.
4. "Hydroids grow on the mother's teeth during pregnancy because she stops feeding"
Somewhat interesting but also irrelevant. Needs to be either tied in to the section or removed, not tacked on to the end as an afterthought. Most people will not know what hydroids are, let alone the significance of them growing on a shark's teeth, so it should probably just be removed. If it can be tied in it also needs to be stated in a less simplistic manner and without using the anthropomorphized term "mother."
It is worth noting that the primary source listed for reproductive data is thirty years old; positively ancient by scientific standards.
There has also been an interesting development in the last few years by Australian researchers attempting to breed the species that may be a relevant addition to the Conservation section. They have attempted to create an "artificial uterus" utilizing a system with different chambers to rear the young separately from one another, preventing cannibalism and yielding a higher number of offspring.
I don't know if anyone is still working on this article as it looks like the last activity was a year ago. I will check back and can make changes if no one else is active. CrisisRose (talk) 01:41, 23 February 2013 (UTC)
Benthic
[edit]In diet, benthic is referenced as "free swimming". I think that pelagic is a more accurate term. I know my students have moved on, is anyone vested in this article at present? --JimmyButler (talk) 05:53, 24 August 2013 (UTC)
Edits removing large parts of text (check needed)
[edit]A long series of edits by user:Jwhferguson (hasn't been active on wiki for a long time) resulted in removals of fairly large sections from the article. Some changes were fine, but other removals seem questionable, especially in the "Description" section. I don't have the time at present, but it might be worth checking if it is worth saving some of it. 62.107.193.67 (talk) 03:52, 21 March 2014 (UTC)

Mediterranean
[edit]The top of the article states that the last sighting of the sand tiger shark in the Mediterranean Sea was in 2003, but has no citations since October 2021. Later in the article, it's said that it's present in the Mediterranean, with no allusion to its presumed(?) extinction. The range map is from 2005, but does depict ranges near several mediterranean countries.
Is it or is it not currently present in the Mediterranean sea? This[1] aquarium in 2023 seems to think it is. 151.67.212.58 (talk) 10:42, 5 July 2024 (UTC)
