Bdelloids, although aquatic animals, not only are efficient in tolerating desiccation, but are somehow dependent on anhydrobiosis, a circumstance that might represent a key event in their life cycle. If this is true, life in unpredictable habitats should not be seen as the result of competitive exclusion from more 'easy' habitats, but a necessity for long-term survival of a bdelloid rotifer.
