> Q: 2: If desert species can last a long time during "unhealthy" times, can fresh water and Marine species also estivate to bypass bad situations?
Some freshwater species can; others cannot. Uniomerus species (which are freshwater mussels) seem able to live for at least two years on a shelf; or, in nature, in a dry creek bed for extended periods.
