Spawning times of male and female D. cylindrus colonies in Curaçao relative to local sunset time. Blue rectangles depict the window of observation. Blue lines denote the time period when males were seen spawning. Yellow lines denote observations of females spawning. Dotted lines indicate probable spawning that was not observed because a diver arrived at or departed from a colony while it was spawning heavily. All times are presented as minutes after sunset (MAS) relative to the Willemstad, Curaçao sunset time on the night of observation.
