er zijn naar het schijnt dieren die NIET sterven van ouderdom en dus eeuwig leven tot ze worden opgegegeten of door 1 of ander ongeluk in de natuur

What?? Animals that are Immortal you ask.
What is Negligible Senescence? Can you believe this has some scientists wondering if human aging can somehow be prevented? This information really brought me to a stand still...
There is an Emerging Area of Aging Research: Long-lived Animals with "Negligible Senescence".
Scientists have found that in some animals their aging process is so slow that it is either nonexistent or too slow to be measured reliably in the laboratory.
Negligible Senescence is what Caleb Finch, a scientist at USC studying this process, has decided to call this slow-aging or non-aging process.
***The animals, that exhibit Negligible Senescence, don’t have a finite life span like other animals. Which means they don’t have a maximum age of life where they would die of old age. They also seem to resist the diseases of old age. They have a life expectancy, or live to an age to which they die of disease, predators, or starvation- but not old age. In this sense, these animals can be considered immortal.***
Perhaps just as interesting, these animals do not have a fixed body size (such as some lobsters, flounders, sturgeons, sharks, alligators. turtles, and whales) they simply increase in body size with time while showing no noticeable sign of aging.
I know what you are thinking. Let me put your mind at ease... The reason why we don’t see 500-year-old alligators the size of houses prowling about is because they have succumbed to the perils of living in the wild.
However, when these animals are kept in zoos free from the external factors that would kill them, they simply grow indefinitely, with almost no decrease of their physical functions- even after reaching full sexual maturity.
Interestingly enough, as these creatures get older, they also become more fertile. The egg laying females actually produce more eggs the older they get. Where as in animals that have a fixed body size, fertility diminishes with age as do the number of offspring they produce.
These animals usually die soon after becoming infertile as nature has little use for an aging animal well past the vital, offspring bearing age. Such an animal is a drain on the rest of the herd or pack.
Classic examples of species exhibiting both of these traits (mortality and immortality) are the Flounder and the Rockfish.
The male Flounder reaches a fixed body size and ages normally, as most animals do, and dies soon thereafter.
***However, the female Flounder grows indefinitely and shows no signs of aging or loss of function with time.***
The Rockfish have both short-lived and long-lived members in the same genus. They range from 12 years for the calico rockfish to 205 years for the rougheye rockfish.

The existence of animals with no fixed life span seems to indicate that “age genes” do exist. Apparently, the cells of these animals never lose their vigor or their ability to reproduce.
It is the cellular structure and functioning, and the DNA and chromosomes of these non-aging animals that some scientists are beginning to research in hopes of finding the "Fountain of Youth" for human beings.

of die effe google search voor Negligible Senescence
de rockfish of flounder fish dus als je die in een bokaal zet en zorgd dat die niet ziek word of word gedood door een andere vis zal die dus NIET sterven van ouderdom
HOW COOL IS THAT???
is nu onderzoek aan de gang om te proberen of men dat ooit op de mens zal kunnen toepassen hehe
