(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.   *Source: Scan a Donut, No Worms*   ## Gallery  -![The two Donut Raion (Donut, No Worms) in the foreground have removed their population of worms.
