All times are listed as the local time in Willemstad, Curaçao (Atlantic Standard Time; AST). Observation windows are presented as minutes after sunset (MAS) and represent the window of time during which divers were directly observing D. cylindrus colonies. *Note that in Curaçao, the full moon on 31 August 2012 occurred early in the day (0959 AST), thus some researchers would choose to count 2 Sept 2012 as the third night after the full moon rather than the second.
