Thirteen-lined ground squirrels can survive in hibernation for over six months without food or water and special physiological adaptations allow them to do so. [6] During torpor, these squirrels maintain hydration by redistributing and storing osmolytes like sodium, glucose, and blood urea nitrogen in different body compartments (to be ...
