Talk:Salmon shark

Maximum age of salmon sharks
I just removed the claim "The average salmon shark lives approximately 40 years" from the article. It was not cited, and I could find no real verification for it. I am unaware of any attempt to estimate the average salmon shark lifespan, but Goldman's thesis (cited in refs) gives a leslie matrix which ends at 30 years (and indicates the vast majority of animals are dead by then). Goldman and Musick's data in their 2006 paper show no animals older than approx. 20 years. If a source for the 40 year claim can be found, I would love to know about it. But as it is, I went ahead and removed the claim from the article. Thoughts or clarifications? --TeaDrinker (talk) 05:21, 24 March 2009 (UTC)

 * I wrote a good chunk of the article in this edit, based on multiple source (including Fishbase) as cited. I would be happy to revise out the sections Graham added originally, but suggest Fishbase is still a reasonable source for the article.  --TeaDrinker (talk) 00:08, 30 March 2009 (UTC)
 * Hmm, it looks like such a revision was already done. --TeaDrinker (talk) 00:54, 30 March 2009 (UTC)

Shark predation
I removed a note about salmon sharks being preyed upon by killer whales. While it is certainly possible (killer whales have been known to take large sharks, although it is very rare--see Fetyl et al 1997, and Pyle et al 1999, both in Marine Mammal Science), I have not come across something demonstrating salmon shark specifically (and given the rarity of marine mammal stomach contents analysis these days, find it fairly surprising). Since they are, in any event, likely a minor source of salmon shark mortality (although the details of salmon shark mortality are not really well known), I have taken the liberty of removing it. --TeaDrinker (talk) 07:21, 29 January 2010 (UTC)

i actually think it should be noted that shark is not an apex predator as it can be a meal to an Orca, as it is well documented fact that Orcas feed on large shark, Great White being very popular among Orca whales for its liver. Therefore salamon shark is not an apex predator. —Preceding unsigned comment added by 188.220.53.72 (talk) 01:21, 17 September 2010 (UTC)
 * I am unaware of any evidence that white shark make up any significant portion of the killer whale diet. Everything I have seen suggests these are rare or chance encounters (a point made in Pyle 1999).  I would be interested to know of evidence of more frequent predation events, however, if you're aware of something I am not.  In general, apex predator refers to species which have no substantive predators in their habitat (rather than theoretical or rare pairings).  In the case of salmon shark, absent evidence they are substantively depredated by killer whales, I suggest that they are indeed an apex predator (I will have to see if they are commonly referred to as such in the literature, although I don't think it would be a controversial claim among Alaskan fisheries scientists).  --TeaDrinker (talk) 03:41, 17 September 2010 (UTC)

Eastern vs. western
"Age and sex composition differences have been observed between populations in the eastern and western North Pacific. Eastern populations are dominated by females, while the western populations are predominantly male...It has been widely speculated that the difference between population differences may be a result of the Japanese fishermen harvesting the male population." This does not quite make sense as Japan is in the western North Pacific, while the coast of North America is in the eastern North Pacific. Should the wording of the sentence be switched? I'm not a salmon shark expert so don't feel that confident doing so. Akwdb (talk) 21:34, 5 June 2016 (UTC)

No mention made of their parasites
These sharks commonly have parasites on their fins that look like strings. These parasites should be described or at least linked to. Will (Talk - contribs) 00:41, 25 March 2018 (UTC)

Image isn't very good
I think the image on this article is pretty poor. Can anyone find a usable one of better quality? 137.70.12.60 (talk) 18:22, 30 May 2023 (UTC)
