the story of the tortoise

I really wanna share the story of a small desert inhabitant with hard crust but soft inside. Theses tortoises live up to 80 years and are capable of surviving without water for more than a year. This is possible due to their uberbladder, which retains liquid and makes it reaccessible for the tortoise's metabolism. Isn't that amazing? However, not everything in their life is as easy as it sounds like. Desert tortoises suffer from a mean enemy, know as man. Such one approaching a tortoise or even touching it, can terrify the latter in such a way, that it urinates, loosing too much liquid to survive until the next rain. Poor thing.
