The cycles arise from the different tidal properties of the moon when it is frozen and when it contains an ocean. The implications for life on Enceladus don't seem particularly good.

But I think that maybe life is possible on the surface. Obviously it won't be anything like Earth, because such organisms would live at 90atm pressure, use liquid sulfur as solvent or merely for transportation of substances and they won't be made of the same carbon-based substances we are made, like carbohydrates and proteins. They would be based on liquid sulfur ...
