"Life can exist on orders of magnitude lower power and sustain their living cells for orders of magnitude more years than previously thought possible. This means that many of these living beings bump up against the energetic limits of life, and in the process seem to have cracked the code for near-immortality. These types of intraterrestrials have such extremely long lifespans that we need a new term to describe the type of extremophiles that they are. The word aeonophiles fits, since they like (-phile) long periods of time (aeon-)."
