Life history[edit]

For shark lifespans strange the Greenland shark's not mentioned as possibly longest lifespan it is believed to live 200years, even the wikipedia entry for that shark says that. Suggest that gets edited. — Preceding unsigned comment added by 2.123.88.97 (talk) 11:53, 12 July 2016 (UTC)

Not just 200 years. Researchers have calculated that the greenland shark may actually live up to 512 years! (references at https://en.wikipedia.org/wiki/Greenland_shark) — Preceding unsigned comment added by 84.215.120.113 (talk) 15:53, 15 August 2016 (UTC)

In the section Shark#Life history, please change:

  • The spiny dogfish has the longest lifespan at more than 100 years

to

  • The spiny dogfish has one of the longest lifespans at more than 100 years

Then add the following (just after "Whale sharks (Rhincodon typus) may also live over 100 years"):

  • Earlier estimates suggested the Greenland shark (Somniosus microcephalus) could reach about 200 years, but a recent study found that a 5.02-metre-long (16.5 ft) specimen was 392 ± 120 years old (i.e., at least 272 years old), making it the longest-lived vertebrate known.[1][2]

Edits by LumaP15[edit]

Have twice reverted edits made by LumaP15 as there was no reason specified for changes and ignores evidence cited by the Curtis article. Rather than continuing an edit war I have modified LumaP15 edits to bring some balance to the section. The issue of shark control is controversial, however it is incorrect to say there is no evidence that drumlines and shark nets do not work. They do work (as evidnced by the Curtis and Dudley articles) but at a cost in killing sharks Ilenart626 (talk) 10:31, 23 August 2017 (UTC).

Advanced Immune Systems?[edit]

Research still goes on. This article (cached because of the popups) implies from this paper that sharks have robust adaptive immune systems.
"This higher proportion of genes involved in adaptive (antibody) immunity function could be a key reason behind the infection-fighting and fast wound-healing abilities of sharks and rays," concluded co-senior study investigator Michael Stanhope, Ph.D., professor in the department of population medicine and diagnostic sciences at the Cornell University College of Veterinary Medicine"
"Could"! So all the snake oil merchants will have to continue waiting for the much anticipated forthcoming affirmation (if any). --Lmstearn (talk) 05:19, 21 November 2017 (UTC)
