Nonnative invasive mollusks degrade aquatic ecosystems and induce economic losses worldwide. Extended air exposure through water bodydrawdown is one management action used for control. In North America, the Chinese mystery snail (Bellamya chinensis) is an invasiveaquatic snail with an expanding range, but eradication methods for this species are not well documented. We assessed the ability ofB. chinensis to survive different durations of air exposure, and observed behavioral responses prior to, during, and following desiccationevents. Individual B. chinensis specimens survived air exposure in a laboratory setting for > 9 weeks, and survivorship was greater amongadults than juveniles. Several B. chinensis specimens responded to desiccation by sealing their opercula and/or burrowing in mud substrate.Our results indicate that drawdowns alone may not be an effective means of eliminating B. chinensis. This study lays the groundwork forfuture management research that may determine the effectiveness of drawdowns when combined with factors such as extreme temperatures,predation, or molluscicides
