Another champion of biodiversity, even if it does not do as well as tardigrade:

Extract from his wiki page: http://fr.wikipedia.org/wiki/Proteus_%28Amphibien%29
When food is scarce, it reduces its activity and its metabolism. It can even reabsorb its own tissues in the most critical cases. Experiments have shown that he can survive up to ten years without food.
The average lifespan of a protea is estimated at around 58 years [25]. Some individuals have nevertheless been kept in artificial tanks in semi-natural conditions for almost 70 years [26].
There is a 2 page article in the latest S&V that details these survivability and anti aging performance, I will scan it.
So "telomerization" (modification of telomeres to slow down aging, or even cancel it ??) soon available thanks to Olm?
Not even worth it, it has already been identified:

In 1971, Russian biologist Alekseï Olovnikov hypothesized for the first time that the maximum lifespan of cells in culture (Hayflick limit) is correlated with the progressive loss of telomeric sequences. Indeed, during each cell division, the telomeres erode until reaching a critical size which then triggers an entry into senescence of the cell. Telomeres act like a biological clock governing the lifespan of cells. This theory is known as the telomeric theory of aging. He also predicted the existence of an enzyme capable of reversing the process by synthesizing new telomeric DNA sequences: it is called telomerase. The identification of telomerase was made in 1985 by Elizabeth Blackburn and Carol Greider [1]. This work was awarded the Nobel Prize in physiology or medicine in 2009.
