I have a lof of doubt about naked mole- rats immortality. As you mentioned at the age of six month they become mature and female remains fertile all the time. So it means a lot of naked mole-rats around us but we don't see much. This doesnot make it true that these species are biologically immortal. Any way its my 2 cent opinion. Any way amazing creature with unique ability to have no change in DNA. Thanks for sharing about naked mole-rats and its characteristic.

While they might be immortal in theory (meaning they don't die from being too old), they could still be killed be predators, falling rocks in their caves, and a lot of other things, so they are not at all immoral in a way we often like to think of immortality :)
Yes that was the thing which i was missing. Thanks for pointing out this scenario. I was missing this valid point but still difficult to digest immortal theory, even though every thing is possible. I think all you want to say their DNA donot chane with their growth and they remain superfit.
Yeah, that is pretty much what biological immortality is. Think of it as a 1000-year old human being as fit as a 30 year old, and both of them having the exact same chance to die from other causes. In normal situations older people have a much higher chance to die than those who are younger.
