In the "Winterized Mollusks" thread, Paul Monfils cites some interesting
observations on mass mortality (death) of mollusks, which can often be of
particular species. I'd like to hear from people who have witnessed such
events, on land, sea, or freshwater. What species were involved in the mass
mortality? What was the cause of death, if known? In what season or month
did this occur?
