(Alternatively, they have left in search of a better host.) This may be a reproductive strategy, a defensive reaction to the worms turning on and feeding upon the sponge, or a response to environmental stress.  -Assessment: unclear how long the donut can survive without its primary food supply. Terrestrial corals survive only days to weeks after bleaching.+**Assessment:** unclear how long the donut can survive without its primary food supply.
