Wikipedia:WikiProject Sharks/Items needing attention

From Wikipedia, the free encyclopedia

This is a clearing house for items that need attention but aren't so urgent that they need changing immediately. List the item under the appropriate heading for somebody to check at a later date

If your can fix one of the problems, please fix it and then remove it from the list if you have a definitive fix, or make a note against it if it is a problem that is likely to reoccur.

What to list here:

  • Requests for images to illustrate articles - diagrams, maps, photos
  • Requests for citations for statements made in articles (including generally uncited articles)
  • Random facts that may make good additions to articles if they can be confirmed, or statements that clash between different articles
  • Problems with images - range maps that appear to be wrong or questionable, images that appear to be wrongly identified, images that need identifying
  • Problems with nomenclature - clashes of name, missing names etc.

  • Shark has a lack of citations throughout

[edit] Unconfirmed "facts"

[edit] Longest gestation

  • We have Frilled shark claiming "It has been suggested that the gestation period is about 3.5 years, which would give the frilled shark the longest gestation of any vertebrate, considerably exceeding the elephant's period of 22 months." (But see latest statement in Frill shark GrahamBould 15:21, 1 October 2006 (UTC)
  • basking shark states " Gestation is thought to span over a year (but perhaps 2 or 3 years)"
  • Spiny dogfish does not mention any gestation period
  • In shark we state "Dogfishes also have the longest known gestation period of any shark, 22 months"

References

  • [1] spiny dog fish, 24, = longest
  • [2] claiming basking shark have the longest without stating any time
  • [3] claiming frill shark is at least 3.5y
  • [4] stating basking probably 3.5y and maybe 14m

So basically I have no idea what is correct and suggest that we should write some kind of summary of these unknow facts and make it common in all shark pages mentioning this. Suggestions? Stefan 14:04, 8 September 2006 (UTC)

The FAO catalogue gives "probably 1-2 years" for the Frilled shark, "variously reported as 18-24 months, and may vary by area" for the spiny dogfish, and nothing for the basking shark. Since the spiny dogfish is the only known range I think we should use this. Something like : Dogfishes have the longest recorded gestation period of any shark, at between 18 24 months". I've only answered this so quickly as I was looking at it in the shark article earlier. Yomanganitalk 15:51, 8 September 2006 (UTC)

[edit] Problems with images

Thats a blacktip reef shark isn't it. The only other one i could think it of being is the blacktip shark but they don't have quite an obvious black mark on the top of the dorsal fin chris_huh 09:44, 8 September 2006 (UTC)
That's what I thought too, but the shape seemed a bit off, so I wanted to confirm. Yomanganitalk 09:48, 8 September 2006 (UTC)
Looks like blacktip reef shark to me, but I will ask an expert, will get back. Stefan 13:19, 8 September 2006 (UTC)
My 'expert' says that it probbaly is a blacktip, but it is not the best of pictures so he is not 100% sure, the fact that it is a picture from a tank also implies that it is a blacktip which is more common than the alternatives in tanks. Stefan 00:08, 9 September 2006 (UTC)
I made it worldwide due to this reference. I'm not sure which is correct, I have read that there is speculation that they go deep and off shore during sesons that they are not costal and shallow, but I really do not know. Stefan 13:19, 8 September 2006 (UTC)
It appears to be referred to as coastal in every source I can find, and while they are migratory I don't think the migration route is normally counted as part of their range. Just looks a bit strange if anybody compares the text to the range map, but I listed it here as there are more range maps that need doing before we start going back to ones that need refining.

See [5] for ref for dist map that matches very well with the one we have, except that it also have red sea. Stefan 14:46, 8 September 2006 (UTC)
I can add Red Sea. I copied the map from a book, which doesnt show it in the red sea, which is strange. I think a lot of the maps need to be checked since a lot of the maps are different when coming from different sources. chris_huh 16:16, 8 September 2006 (UTC)
FAO catalogue doesn't show it in the Red Sea - maybe I'll have to splash out on the updated version. Yomanganitalk 16:45, 8 September 2006 (UTC)
If the picture Image:Grey_reef_shark2.jpg is a gray then they exists in the red sea, I took the picture and it for sure was in the red sea! When I have made some distribution maps all the source I have found have been different, so I think it is very clear that shark distribution is very unknown. Stefan 00:05, 9 September 2006 (UTC)
