Other long-lived organisms
I understand that for certain freshwater fish -- for example,
- sturgeons -- if they manage to live past a certain age, they, in effect, become immortal & can only die from accident or the intervention of man. (Sorry, no cite)
- Oliver Rackham claims that the Queen's Oak at Huntingsfield, Suffolk is "about a thousand years old" -- as well as "the wonderful pollards of Winsdor Great Park -- while some coppice stools in the Bradfield Woods, Suffolk, are "among the oldest living things in Britain (at least a thousand years)". (Trees and woodland in the British landscape [London: Phoenix Press, 2001], pp. 14f.)
- I've also seen mention that Baobab trees are very long-lived, easily over a thousand years. Does anyone have more information? -- llywrch 00:53, 14 December 2006 (UTC)
Lobster, crab can both live practically eternally - i'll try to find a cite
Since the Turritopsis nutricula is the only known immortal species, it's likely that the oldest continuously living animal on the planet is a jellyfish of this species (I would have thought). Can we have some coverage of this in the article, please. --Wragge 16:30, 1 November 2007 (UTC)
- It is not known to be immortal, according to the reference given in the article. Just because an animal can switch between a "mature" and "immature" state does not mean it can do so indefinitely. The individual cells may still age continuously. --Roentgenium111 (talk) 22:25, 30 July 2009 (UTC)
Clone colony one plant?
In a discussion on the science ref desk someone pointed out that clones are no more alike than identical twins. In which case the clonal colonies can hardly be regarded as one plant. I don't suggest removing them, but if the comparison makes sense it might make sense to make it in the article because it rather puts things in perspective. DirkvdM 19:15, 2 October 2006 (UTC)
- Clonal colonies are one plant. They are physically contiguous, like your body. So it's more like conjoined twins, although in the case of plants there is no meaningful distinction between two and one if they're connected and genetically identical. In animals there is.
No meaningful distinction between plant clones and plant individual
All plants are modulary organisms (as well as lower animals such as sponges). Therefore the distinction in the article between plant clones and individual plant specimens is actually irrelevant.
Also in a single plant 'individual', there will be no cells living throughout the life-time of the plant. Leaves are shed, of course (also needles), and in the stem, the cells making of the xylem and phloem are only functional as young (and dead already in the case of xylem). The same token applies to major roots whereas the smaller ones are shed or withered away.
Hence, in a way the clones (like Pando) are just as modulary as is a single maple.
Our way to think of 'individuals' is (too) heavy influenced of ourselves being eumetazoans. Plants simply aren't like that. That's why they might be immortal (also having high activities in the meristems of the telomerase enzyme).
I'm not a botanist, but the Norway Spruce don't strike me as colonies like Pando. The oldest root has itself been dated to about 8000 years old. I would call a root a part of an individual organism, even if the trunks are more temporary. What defines a tree? Granted, the trunk is what we supra-surface organisms notice most of the time, but isn't a root an important part of a tree? And so wouldn't a root that has been growing and maturing for 8000 years represent a single organism rather than a colony? In the case of Pando, by contrast, I don't think anyone's claiming that any given root has persisted for thousands of years. Jbening (talk) 04:36, 19 April 2008 (UTC)
- Each and every clonal organism can, in itself, be considered an individual organism - it'd just be a really really big individual organism. Whether or not it remains a continuous cell mass, isn't of massive importance (as trees can be divided and fused and still survive perfectly well); what is important is how genetically identical the trees are - supra-surface stems that are identical must have been born of the same 'flesh'. 126.96.36.199 (talk) 04:56, 26 April 2008 (UTC)
List of Long-lived species?
Is there a comparable list for long-lived species? I can't find one but it would surely be of interest & would add relevant context for this list. --lquilter 01:22, 23 January 2007 (UTC)
Autochthony writes - 2009 August 25 at 2010z - if you can access a copy of the Guinness Book of Animal Records, 2nd edition, by - oe Ed. - Gerald Woods, FZS, it lists speeds and ages [maxima] by species, in the end covers.
oldest domesticated animal examples
why isn't there a page for common longest lived species such as cats, dogs, pigs, goats, cattle, etc? i would have thought that would have been first on your list of things to do...
It strikes me as remarkable that we have so much information on (fascinating, but of very narrow relevance) Guiness-Book-ish "world records" for animals, yet we seem to have no articles listing, or even discussing in any detail, the average lifespans for any organisms (ideally with separate listings for animals in the wild and in captivity). Surely the norm is much more important than the extreme exception. In addition to there being no centralized location for such information on Wikipedia that I can find, our treatment of lifespan also seems to be inconsistent (e.g., wild vs. captive ages), well-hidden, or entirely absent in the individual species' articles; and I haven't been able to find any reputable sources online which list many lifespans either. Does anyone know of where one might find such reputable, sourced information? Is there any centralized hub of such data, at the very least for certain subgroups of organisms (e.g., all mammals, or all amphibians, etc.) if not for all life? -Silence (talk) 17:10, 6 August 2009 (UTC)
It is mentioned on the black choral page that a subspecies of black coral was found to be 4,265 years old. It should be added at the top of the section as the oldest living animal. — Preceding unsigned comment added by 188.8.131.52 (talk) 14:54, 21 October 2011 (UTC)
According to http://www.agelessanimals.org/ the Rougheye rockfish can reach 205 years "In a very intriguing analysis, the project's Fish Ecologist, Gregor M. Cailliet, determined that rockfish have both short-lived and long-lived members in the same genus (Cailliet 2001). He found that maximum rockfish longevity ranges in age from 12 years for the calico rockfish to 205 years for the rougheye rockfish." This research group is currently studying the reasons for the longevity and has so far examined telomerase and protein turnover. Star A Star (talk) 06:54, 27 November 2011 (UTC)
great white shark - based on two sketches, apparently, over a century apart. Note that I feel this is plausible, but it would be nice to have some comparatives; like a couple of interim sketches, or some research on - say - mother-daughter dorsal similarities. But mighty interesting . . . Autochthony has written. —Preceding unsigned comment added by 184.108.40.206 (talk) 20:08, 25 August 2009 (UTC)
- Methuselah (tree) is clearly the oldest organism, and doubtless Kama Chinen is the oldest mammal, but doesn't sound right that Man has surmounted Chordata. 220.127.116.11 (talk) 17:21, 23 January 2010 (UTC)
Not sure if I'm putting my problem in the right place, but on the page it says that 'Tu'i Malila, a Radiated tortoise, died at an age of 188 years in May 1965, the oldest verified vertebrate'. Surely a Bowhead whale that lived to 211 years old and Koi that lived to 226 (cited as legitimate a few entries above) are older living vertebrates? — Preceding unsigned comment added by 18.104.22.168 (talk) 21:15, 20 October 2012 (UTC)
Mammalian cell line
I'd argue that the canine transmissible venereal tumor deserves some mention on this page, but I'm not really sure what would be the best way to do that. It's not really a mammal or even an animal in most traditional senses of those words, but it's still mammalian in some sense and it's certainly quite old. Thoughts, anyone? 22.214.171.124 (talk) 20:23, 7 June 2013 (UTC)
Noah's dove's olive tree?
"They are also known to be the worlds oldest olive trees as well as the source of Noah's dove olive peace branch." Is it really known? /: — Preceding unsigned comment added by 126.96.36.199 (talk) 21:15, 11 December 2012 (UTC)
- This offended my brain too, so I modified the language. People can believe what they like, but they can't claim it to be fact. — Preceding unsigned comment added by 188.8.131.52 (talk) 22:10, 11 December 2012 (UTC)
Why was most of this page deleted?
- No idea. :) No explanation was given by User:Erforever88 for his removals. I've restored the content. --Kurt Shaped Box (talk) 03:25, 8 March 2010 (UTC)
Multiple issues tag
I've added this after coming to the entry while researching this issue for a project. I believe it is justified because (1) many of the references are low-quality and potentially untrustworthy (2)There is no proper discussion of the key issue of dormancy with bacteria (3) there's insufficient references to the recent work on eg actinobacteria, which appear to be the oldest organisms at around 500 kyr.
