> in the case of rotifers, if they are alive, either they are hibernating or suspended, or reanimation really is the instantiation of a new rotifer.
It is not a new rotifer. Firstly, any life is a continuation of a previous life. Tree grows from a seed, and the seed was grown on a tree. There is one likely exception of abiogenesis a few billions of years ago, but I think it will be hard to claim that roftier's reanimation is a case of abiogenesis.
Secondly, it is the same rotifer, made of the very same molecules roughly in the same places of its body. Some molecules were damaged and they are repaired, but it is the inherent property of life is the striving for homeostasis, life always do that. Cells spend ~30% of their metabolism budget on ion transport through their membranes to keep required differences in concentrations of ions between inside and outside.
